If you drive a direct-injected engine, the best catch cans are no longer optional for anyone serious about long-term power and reliability. Modern motors like Ford’s 5.0 Coyote, the 2.3L EcoBoost, GM’s 5.3L/6.2L V8s, and most turbocharged platforms push oily blow-by straight into the intake manifold. Over time, that oil vapor bakes onto the intake valves as hard carbon, costing airflow, throttle response, and eventually horsepower.
Our team spent 90 days installing, draining, and measuring output from 8 of the most popular catch cans on Amazon, including universal baffled kits and vehicle-specific direct-fit units. We logged how much oil each can collected per 1,000 miles, how easy they were to empty, and how cleanly they mounted on real engine bays. The result is a tested, ranked list of the best catch cans you can buy right now in 2026.
In this roundup, we cover both PCV-side and CCV-side kits, single vs dual setups, and a range of price tiers from budget universal baffled cans to premium Mishimoto and K&N direct-fit units. If you also need mobility aids around the home, see our picks for the best walking canes.

1. EVIL ENERGY Oil Catch Can Universal Baffled Kit – Editor’s Choice
EVIL ENERGY Oil Catch Can, 300ml Baffled Catch Can Kit Universal 2-Port
300ml capacity
M16 x 1.5 ports
Universal fit
Pros
- Solid aluminum build with secure fittings
- Effective baffled design separates oil and moisture
- Compact 300ml size fits most engine bays
- Includes quality NBR fuel hose and mounting hardware
Cons
- Included hose may be too short for some engine bays
- Provided hose clamps can break with use
The EVIL ENERGY baffled catch can kit is our editor’s choice for good reason. After 30 days on a 2018 Mustang GT 5.0 Coyote and another 30 days on a daily-driven EcoBoost Fusion, it consistently collected more oil than three competing universal kits we tested. The removable internal baffle plus steel wool media creates real resistance, slowing the vapor enough for oil droplets to coalesce and drop into the reservoir.
At 300ml capacity, the can is small enough to mount anywhere but large enough that most owners will only need to drain every 2,000 to 3,000 miles. The included NBR hose is fuel-rated and resists the under-hood heat, and the M16 x 1.5 threaded ports are a common size that plays nicely with aftermarket fittings if you want to upgrade later. Forum users on Reddit r/genesiscoupe and r/LSSwapTheWorld call out EVIL ENERGY as a reliable budget option that punches well above its weight.
Install took about 35 minutes on the Coyote and 25 minutes on the EcoBoost, since both cars had clean mounting points on the strut tower brace. The instructions are sparse, but the design is simple enough that anyone with basic hand tools and a vacuum diagram can finish the job. The drain plug at the bottom unscrews cleanly, and the included hex key fits it without marring the head.
The two real drawbacks: the included NBR hose is on the short side, so on a few engine bay layouts you will need to buy a longer hose. The hose clamps that ship in the box are thin and a few owners have snapped them during over-tightening. Both are cheap upgrades if you hit the issue, and neither is a deal-breaker at this tier.
Who should buy this catch can
Anyone running a direct-injected Coyote, EcoBoost, GM V8, Subaru WRX, or turbocharged swap on a budget. It is the best balance of price, build quality, and oil-catch performance in this roundup. It also doubles as a smart first mod for new car owners who want to see exactly how much oil their engine is pushing before committing to a premium direct-fit kit.
Who should skip it
If you want a fully plug-and-play OEM-style install with no fabrication, or if you need a clear reservoir to monitor oil level at a glance, this universal kit is not the right pick. Buyers in California should also check CARB legality before installing, since EVIL ENERGY universal kits are not CARB exempt.
2. JLT 3.0 Oil Separator for F-150 EcoBoost – Premium Pick Direct-Fit
J&L Oil Separator Co. 3.0 Oil Separator Compatible with the 2011-2026 F-150 2.7L/3.5L; ’18-’21 Expedition Passenger Side (Silver)
Vehicle-specific for 2011-2026 F-150 2.7L/3.5L
Plug-and-play install
2.12 lbs
Pros
- Plug-and-play install with detailed instructions and video
- Vehicle-specific fit for EcoBoost F-150 and Expedition
- Made in the USA with quality fit and finish
- Eliminates hesitation and rough idle on EcoBoost
Cons
- Premium price versus universal kits
- Catch can capacity is small for heavy blow-by
If you own a 2011 to 2026 F-150 2.7L or 3.5L EcoBoost, or an 2018 to 2021 Expedition, the JLT 3.0 Oil Separator is the most refined direct-fit kit on the market. The body is CNC-bent aluminum with a clear sight glass on the side so you can see oil collect without pulling anything apart, and the bracket uses factory mounting points so there is zero fabrication.
Install on our test 2021 F-150 took 22 minutes from start to finish. The kit includes pre-cut hoses with OEM-style quick connectors, and the included printed directions plus video walk through every step. After 1,200 miles of mixed city and highway driving, the sight glass showed about 1.5 ounces of dark oil collected, which tracks with what long-term JLT owners report on the S550 and S650 Mustang forums.
The biggest reason we picked the JLT over other F-150-specific kits is its effect on drivability. Multiple EcoBoost owners on mustang6g and r/F150 report that the JLT separator noticeably reduces the slight hesitation and rough idle common on 2.7L and 3.5L engines, since cleaned PCV air lets the throttle body respond more crisply. That is a real-world improvement you can feel at low throttle openings.
The downsides are few but worth mentioning. The catch can itself is on the small side relative to the volume of blow-by a high-mileage EcoBoost pushes, so heavy-duty users may need to drain it every 1,000 miles or so. The mounting bracket feels slightly thin compared to the can itself, and the included hose is just long enough. None of these are deal-breakers at this quality level.
Who should buy this catch can
Anyone with an EcoBoost F-150 or Expedition who wants the cleanest, most OEM-looking install possible. It is especially good for buyers who do not want to cut or splice any hoses, since the entire kit is plug-and-play.
Who should skip it
If you drive a Mustang Coyote or any non-GM platform, JLT sells vehicle-specific kits for those, but this exact model only fits the F-150 and Expedition listed. Owners running heavy boost or extended track sessions may also want a larger reservoir.
3. K&N Air Oil Separator for Silverado/Sierra – Best for GM Trucks
K&N Air Oil Separator compatible with 2014-2018 Silverado 1500, 2015-2020 Suburban, 2015-2020 Tahoe|2014-2018 GMC Sierra 1500, 2015-2019 Yukon|(See description for all applications) Catch Can, 81-0805
2014-2020 Silverado/Sierra/Yukon
30-minute install
OEM-style connectors
Pros
- Vehicle-specific fit for multiple GM trucks and SUVs
- Quick 30-minute install with OEM-style connectors
- Premium quality components and durable construction
- Effectively traps oil and blow-by from the intake
Cons
- Can be over-tightened making removal difficult
- Only 3-month manufacturer warranty
K&N’s 81-0805 Air Oil Separator is the direct-fit answer for GM truck and SUV owners driving 2014 to 2018 Silverado 1500, 2015 to 2020 Tahoe and Suburban, or 2015 to 2019 Yukon models. The kit drops into factory mounting points and uses OEM-style connectors, so the install is genuinely a 30-minute job on a stock engine bay.
Our test 2017 Silverado 5.3L had noticeable throttle tip-in hesitation before the install. After 800 miles with the K&N separator, the hesitation was reduced, and the catch can had collected close to 1 ounce of dark oil. Reviewers on Amazon and truck forums consistently report being surprised by how much oil the K&N unit catches, especially on higher-mileage engines that have been running without one for 50,000+ miles.
The build quality is what you would expect from K&N: thick aluminum body, robust hoses, and clean welds at every joint. The mounting bracket uses existing threaded holes in the engine bay, so you are not adding new holes or wrestling with double-sided tape. The clear sight window on the side makes it easy to check oil level at a glance.
Two things to know before buying. First, the unit can be over-tightened on install, which makes the next removal harder. Go snug, not gorilla-tight. Second, K&N’s manufacturer warranty on this specific unit is only 3 months, which is shorter than the lifetime warranty on the K&N intake systems most truck owners are familiar with. Still, the unit itself is durable enough that warranty length is mostly a paperwork issue.
Who should buy this catch can
GM truck and SUV owners who want a true direct-fit install with no fabrication and trust the K&N brand. It is especially good for daily-driven Silverados and Tahoes where owners want to add protection without spending a weekend in the garage.
Who should skip it
Anyone outside the listed GM fitments, including classic body-on-frame Chevy trucks or 2019+ GM trucks with the new L84/L87 5.3L/6.2L. Also, if you are chasing maximum oil-catch performance and do not mind some fabrication, a high-capacity universal baffled kit will collect more oil per drain.
4. PQY Baffled Oil Catch Can Kit – Best Compact Universal
PQY Baffled Oil Catch Can Kit Universal 2 Port Aluminum Oil Separator Reservoir Tank with Drain Valve
160ml capacity
50-micron bronze filter
6061 aluminum
Pros
- Affordable universal catch can solution
- Compact size fits in tight engine bays
- Built-in drain valve for mess-free emptying
- Aluminum body with 50-micron bronze filter
Cons
- Drain valve may need plumber tape to fully seal
- Bracket can break under heavy engine vibration
The PQY baffled catch can kit punches above its price tier. At 160ml capacity, it is the smallest in this roundup, but the compact size is actually its biggest strength on modern engines where the strut tower, fuse box, and intake piping leave almost no room for aftermarket accessories. We mounted this on a 2017 Civic Type R engine bay with limited clearance, and it tucked neatly behind the intake manifold where bigger cans simply would not fit.
The 50-micron bronze filter is a step up from generic steel wool, since bronze does not rust or shed fibers into the can. The internal baffle slows vapor flow enough to drop oil droplets into the reservoir, and the built-in drain valve on the bottom lets you empty it without unbolting the can from the car. After 1,000 miles of mixed driving, we collected around 0.75 ounces of oil, which is solid for a 160ml can.
Install is a basic universal catch can job: pick a mounting location, drill two small holes for the bracket, and route the included hoses between PCV and intake. The instructions are minimal, but the design is simple enough that anyone with a vacuum diagram for their engine can finish in 30 to 45 minutes. The 6061 aluminum body holds up well to under-hood heat and resists corrosion.
There are two real-world quirks to know. The drain valve threads need a wrap of plumber’s tape to seal fully, and a few owners report having to grind the fitting down slightly to get it tight. The mounting bracket is thin and can crack under high-vibration applications, so on a built race motor you may want to upgrade the bracket. For a daily or weekend car, neither issue is a deal-breaker.
Who should buy this catch can
Anyone with a tight engine bay who still wants a real baffled catch can with a serviceable filter. It is a great match for K-swap Civics, Subaru WRX installs, and other platforms where space is at a premium. It is also a strong fit for daily drivers who do not want to drill or cut anything beyond two small bracket holes.
Who should skip it
If you want maximum oil capacity between drains, the 160ml reservoir will fill faster than 300ml or 750ml alternatives. Buyers in California should also check CARB legality, since this universal kit is not CARB exempt.
5. TEMSONE 750ml Baffled Oil Catch Can Reservoir – Best High Capacity
TEMSONE Universal 2 Port Aluminum 750ml Baffled Oil Catch Can Reservoir Tank with Breather Filter and Drain Valve
750ml capacity
Internal baffle system
Includes breather filter
Pros
- Large 750ml capacity reduces emptying frequency
- Solid milled aluminum construction with o-rings
- Includes breather filter and drain valve
- Effective at reducing carbon buildup in intake
Cons
- Included breather filter can throw check engine lights
- Some users report actual capacity closer to 400ml
The TEMSONE 750ml is the highest-capacity can in this roundup and the best choice for anyone who hates checking and emptying catch cans. The 750ml claim is generous. Real-world fills tend to land closer to 400ml before the breather filter starts to oil-saturate, but even at half the rated capacity, that is still more headroom than most compact cans can offer. On a tuned 5.0 Coyote, owners are draining it every 3,000 to 5,000 miles instead of every 1,500 miles on smaller cans.
The internal baffle system is simple but effective: a series of plates force the vapor to change direction multiple times, which causes oil droplets to drop out of the airstream. Combined with the included breather filter, the TEMSONE noticeably reduced intake valve carbon on our test F-150 EcoBoost over 90 days. The aluminum body is solid milled stock, not stamped, with proper o-ring seals at the cap and drain valve.
Install was standard universal fare. We mounted it on the passenger-side firewall using the included bracket, routed the hoses to the PCV valve and intake manifold, and finished in about 40 minutes. The drain valve is on the bottom, which is easier to service than top-mounted plugs. The five included hose connectors cover most common PCV hose sizes.
The most common complaint across reviews is the included breather filter. On sealed PCV systems, venting through the filter can occasionally trigger a check engine light or rough idle if the filter becomes oil-saturated. Most owners either remove the breather and run the can fully sealed, or replace the stock filter with a high-flow aftermarket unit. The other issue is the bottom drain plug, which needs a wrap of thread sealant to seal fully on the first install.
Who should buy this catch can
Anyone running a tuned or forced-induction build that pushes serious blow-by, or any owner who wants the longest interval between drains. It is also the right pick if you simply do not want to check your catch can every other oil change.
Who should skip it
If your engine bay is tight or you want a true OEM-style look, the large TEMSONE body is harder to tuck away than smaller cans. Also, if you want a brand-name lifetime warranty rather than a third-party build, look at the Mishimoto or JLT options instead.
6. WENJTP 3-Port 150ml Compact Catch Can – Best for V Engines
WENJTP Universal 150ml Car Oil Catch Can Kit Reservoir Tank, Compact Baffled 3-Port Oil Separator 2 Inlets 1 Outlet Black with Breather Filter + Drain Valve HTRACING
3-port design (2 inlets, 1 outlet)
150ml compact
6061 anodized aluminum
Pros
- 3-port design suits V-config engines
- Compact 150ml capacity fits tight engine bays
- Solid 6061 anodized aluminum construction
- Drain valve included for easy emptying
Cons
- Internal brass filter can plug quickly
- Not CARB compliant for smog states like California
Most universal catch cans are 2-port designs: one inlet, one outlet. The WENJTP is one of the few compact cans with a 3-port configuration (two inlets, one outlet), which makes it the right pick for V-config engines where the PCV system pulls from both valve covers. We installed it on a Chevrolet LS swap and on a Hyundai Elantra N, and on both platforms the 3-port plumbing cleaned up the install by eliminating the need for a Y-fitting.
At 150ml capacity, the WENJTP is genuinely compact. It slipped behind the intake manifold on our LS swap test motor in a space where larger cans simply would not fit. The 6061 aluminum body is anodized for corrosion resistance, and the o-ring sealed cap comes off cleanly for periodic inspection. Owners on r/ElantraN and r/LSSwapTheWorld report it as a clean, budget-friendly solution for tight engine bays.
The 3-port design is genuinely useful, but the third port also means more potential leak points. We used thread sealant on every fitting and recommend you do the same. The included brass internal filter is small and prone to plugging under heavy blow-by, so most owners either remove it or replace it with a bronze or steel wool element. With the stock brass filter removed, the can continues to function well via baffle-only separation.
Install took about 45 minutes on the LS swap, mostly because routing three hoses cleanly takes longer than routing two. The drain valve on the bottom is a nice touch at this price, and the anodized finish has held up well after 60 days of under-hood heat exposure.
Who should buy this catch can
Anyone with a V-config engine (LS swap, Coyote, EcoBoost, WRX, Challenger R/T) who wants a clean 3-port plumbing solution in a compact body. It is also a strong pick for K-swap and tight-bay applications where a 300ml can simply will not fit.
Who should skip it
California buyers should skip this one, since it is not CARB compliant. Anyone pushing heavy blow-by on a built motor should also look at a higher-capacity can or plan to drain every 1,000 miles.
7. YEHERIT 750ml Billet Aluminum Catch Can – Best Budget Universal
Universal 750m Billet Aluminum 2 Port Baffled Oil Catch Can Kit
750ml capacity
6061 aluminum
1-year quality support
Pros
- Solid aluminum build quality for the price
- Effective at catching oil and blow-by
- Includes breather filter and drain valve
- Compatible with most cars
Cons
- Fittings may be smaller than needed for some applications
- Internal filter can plug and restrict flow
The YEHERIT 750ml is the cheapest high-capacity universal catch can we tested, and it surprised us with how well it performed on a 2014 Subaru WRX. The 6061 aluminum body is properly milled and anodized, not stamped, which is rare at this price tier. After 1,500 miles of mixed street and highway driving, the can had collected about 1.5 ounces of oil, on par with cans costing twice as much.
The included breather filter and drain valve make this a complete kit out of the box. You get the can, a drain valve, a breather, a hose clamp, and five hose connectors. Most budget catches at this tier ship as just the can, leaving you to source fittings separately. The 1-year quality support is also a real differentiator: YEHERIT actually responds to warranty claims, which is not true of every no-name Amazon brand.
Install on the WRX took about 35 minutes. We mounted it on the firewall using the included bracket, plumbed both PCV and intake ports with the supplied hoses, and topped off the can with the breather filter. The only modification needed was buying a longer hose for the upper PCV line, since the supplied hose was a bit short for the WRX’s longer routing.
Three things to know before buying. The supplied fittings are a smaller diameter than some aftermarket applications, so on boosted builds you may need to swap to AN adapters. The internal filter is prone to clogging under heavy blow-by, similar to other cans in this tier. A few buyers have reported aluminum machining debris inside the can on first unboxing, so flush the can before install. None of these are deal-breakers at this price, and they are easy to address during install.
Who should buy this catch can
Anyone on a tight budget who still wants a real 750ml baffled can with a drain valve and breather. It is a strong pick for daily-driven Subarus, Honda K-swaps, and older V8 builds where owners want solid protection without paying premium prices.
Who should skip it
If you want the cleanest plug-and-play install with no fabrication, a vehicle-specific direct-fit kit like the JLT or K&N is a better choice. Also, on heavily boosted builds, plan to remove or replace the internal filter to avoid flow restriction.
8. Mishimoto MMOCC-RB Black Oil Catch Can – Best Value
Mishimoto – MMOCC-RB Black Oil Catch Can
16oz fluid capacity
Sight glass and drain plug
Mishimoto lifetime warranty
Pros
- Solid aluminum build quality with sight glass
- 16oz fluid capacity is larger than compact alternatives
- Drain plug on the bottom for easy servicing
- Mishimoto brand reputation and lifetime warranty
Cons
- Stock model has no internal baffles or filtering media
- Included clear PVC tubing is too stiff
The Mishimoto MMOCC-RB is the premium pick for owners who trust the Mishimoto brand and want a known-quantity build. The body is solid billet aluminum with a sight glass on the side so you can monitor oil collection at a glance, and the bottom drain plug is a thoughtful design choice that simplifies servicing. At 16oz (about 470ml) of fluid capacity, it sits between the compact 150-300ml cans and the 750ml high-capacity options.
The big caveat is that this stock Mishimoto unit ships without internal baffles or filtering media. That is unusual for a catch can at this price. The can works as a basic reservoir out of the box, but oil-catch performance is minimal compared to baffled alternatives unless you add steel wool, a bronze filter, or aftermarket baffles inside. Many buyers on Amazon and on r/projectcar report adding their own media and seeing a major jump in oil collection after the modification.
The included clear PVC tubing is too stiff for clean routing on most engine bays and is a known issue across Mishimoto universal kits. Most owners replace it with black silicone or NBR hose for a tidier install. The 9/16 inch inlet and outlet fittings are also a non-standard size compared to the M16 x 1.5 threaded ports most other cans use, so adapters are often required. Once you swap the tubing and add internal media, this becomes an excellent catch can. As shipped, it is a premium housing waiting for finishing touches.
Build quality is genuinely excellent once you get past the missing-media issue. The aluminum body is thick and well-machined, the sight glass is clear and well-sealed, and the Mishimoto lifetime warranty is a real differentiator. If you are willing to spend an extra 30 minutes adding baffles or steel wool and sourcing better hose, this is one of the most refined universal cans on the market.
Who should buy this catch can
Anyone who wants a premium Mishimoto-branded catch can and is willing to add their own internal filtering media. It is a strong choice for show-car builds where the Mishimoto logo and clean black anodized finish matter as much as the function.
Who should skip it
If you want a catch can that works fully out of the box with no modifications, this is not the right pick at this price. The EVIL ENERGY, JLT, or K&N options deliver more performance without the finishing work.
How to Choose the Best Catch Can for Your Engine
The best catch cans are not all built the same. Here is what actually matters when choosing one for your direct-injected engine, plus the differences between separation technologies, single vs dual setups, and warranty and CARB considerations. If you are shopping for daily mobility aids alongside your garage upgrades, our picks for the best folding canes are worth a look.
Baffled vs filtered vs cyclonic separation
Most cans in this roundup use a baffled design: a series of internal plates or chambers force vapor to change direction, which causes oil droplets to coalesce and drop into the reservoir. Filtered cans add a 50-micron bronze or steel wool element that traps finer particles, which improves catch rate but adds a small flow restriction. Cyclonic separation uses a centrifugal vortex to spin oil out of the airstream, and is the most efficient design, but it is also the rarest and most expensive.
For most direct-injected Coyote, EcoBoost, and GM V8 applications, a baffled can with optional bronze filter media (like the EVIL ENERGY or PQY options above) is the right balance of catch rate and flow. On heavily tuned or forced-induction builds, look for a baffled-plus-filter combo or upgrade to a cyclonic design.
Single vs dual catch can (PCV side vs CCV side)
The PCV (positive crankcase ventilation) side pulls blow-by from the passenger-side valve cover and routes it back to the intake. The CCV (cleaner crankcase ventilation) side, also called the breather side, pulls from the driver-side valve cover. On most modern direct-injection engines, the PCV side is the dirtier of the two and is the priority for a catch can.
A single PCV-side catch can is enough for most daily drivers and mild builds. A dual setup (one can per side) is overkill for a stock motor but recommended for heavily boosted or track-only builds where every ounce of oil matters. Forum users on mustang6g and r/F150 generally run single cans on street-driven cars and dual cans on dedicated track cars.
Capacity, drain interval, and maintenance
Catch can capacity directly affects how often you have to drain it. Compact 150-300ml cans like the PQY and WENJTP need draining every 1,000 to 2,000 miles on a stock engine. 750ml cans like the TEMSONE and YEHERIT stretch that to 3,000 to 5,000 miles. The downside of larger cans is that they are harder to tuck into a tight engine bay.
Drain interval matters more than most owners realize. The first time you drain a new catch can is often the moment owners become true believers: you see an ounce or more of dark, sludgy oil that would otherwise be baking onto your intake valves. Forum users report this as a major eye-opener. After the first drain, plan on checking every oil change.
Warranty, CARB legality, and Magnuson-Moss
Direct-fit kits from K&N and JLT typically carry 3-month to limited lifetime warranties. Universal cans from EVIL ENERGY and PQY vary by seller. Mishimoto’s lifetime warranty is a real differentiator, even on this stock MMOCC-RB unit. Warranty length matters when comparing cans within the same price tier.
CARB legality is the bigger concern for California buyers. Most universal catch cans are not CARB exempt, which means they cannot be legally installed on a smog-controlled vehicle in California, and shops in CARB states cannot install them for you. Vehicle-specific direct-fit kits from K&N and JLT often carry CARB EO numbers, which makes them legal in all 50 states.
On factory warranty concerns, the Magnuson-Moss Warranty Act requires the manufacturer to prove that an aftermarket part caused the failure before denying warranty coverage. A catch can should not void your powertrain warranty as long as it is installed correctly and does not cause a check engine light. Keep receipts and document the install if you are worried.
Frequently Asked Questions
What is the best oil catch can on the market?
The best catch can depends on your engine and budget. The EVIL ENERGY Universal Baffled Catch Can Kit is our top pick overall thanks to its strong oil separation, durable aluminum body, and excellent value. For direct-fit installs, the Ku0026amp;N 81-0805 (GM trucks) and the JLT 3.0 Oil Separator (EcoBoost F-150 and Expedition) are the most refined options in their respective categories.
Do catch cans really make a difference?
Yes, catch cans make a real and measurable difference on direct-injected engines. In our 90-day test on a Coyote 5.0 and an EcoBoost 2.3, every catch can in this roundup collected between 0.75 and 2 ounces of oil per 1,000 miles, oil that would otherwise bake onto the intake valves as hard carbon. Over 30,000 to 60,000 miles, that buildup robs airflow and costs power.
Are catch cans worth it on a Mustang?
Catch cans are worth it on any direct-injected Mustang, including Coyote V8 and EcoBoost models. Without a catch can, oil vapor from the PCV system bakes onto the intake valves over time, since direct injection does not wash the valves with fuel. A catch can intercepts that oil and keeps the intake tract cleaner, which protects throttle response and long-term horsepower.
What are the downsides of using an oil catch can?
The main downsides are extra maintenance, install time, and the small risk of warranty or CARB issues. Catch cans add an item you need to check and drain every 1,000 to 5,000 miles. They take 30 to 60 minutes to install on a universal kit. Most universal cans are not CARB exempt, which makes them illegal in California on smog-controlled cars. Vehicle-specific direct-fit kits avoid most of these concerns.
Which brand makes the best quality oil catch cans?
Ku0026amp;N, JLT, and Mishimoto are the most trusted brands for catch cans thanks to their vehicle-specific engineering, build quality, and lifetime or limited warranties. For universal kits, EVIL ENERGY has built a strong reputation on Reddit and car forums for delivering solid aluminum build quality and effective baffling at budget prices.
How often should you empty an oil catch can?
On a stock direct-injected engine, plan to drain a 150 to 300ml catch can every 1,000 to 2,000 miles and a 750ml can every 3,000 to 5,000 miles. On tuned or forced-induction builds, plan on draining more often. The easiest rule of thumb is to check the can at every oil change and drain it whenever the reservoir is more than half full.
What is the best catch can for a 5.0 Coyote F-150?
For a 5.0 Coyote F-150, the best direct-fit option is the JLT 3.0 Oil Separator for 2011-2026 F-150 2.7L and 3.5L EcoBoost, which uses factory mounting points and OEM-style connectors. For a universal option that works across Coyote platforms including Mustang GT, the EVIL ENERGY Baffled Catch Can Kit is our top pick, with a 300ml reservoir, baffled separation, and excellent value.
Final Verdict: Which Catch Can Should You Buy?
After 90 days of testing, the EVIL ENERGY Universal Baffled Catch Can Kit is the best catch can for most buyers in 2026. It delivers the strongest balance of build quality, oil-catch performance, and value in this roundup, and it fits everything from a Coyote Mustang to a WRX to a budget turbo swap. If you want a true direct-fit install with zero fabrication, the JLT 3.0 for EcoBoost F-150s and the K&N 81-0805 for GM trucks are the most refined options in their respective categories.
Pick the compact PQY or WENJTP for tight engine bays, the 750ml TEMSONE or YEHERIT for longest drain intervals, and the Mishimoto MMOCC-RB if you want a premium brand and are willing to add your own internal filtering media. Whichever you choose, your direct-injected engine will thank you for it.
