Oil Catch Cans for Enhanced Engine Performance

What This Category Covers

Oil catch cans intercept oil vapor and blow-by gases from the PCV system before they recirculate into the intake tract, reducing carbon buildup on intake valves and preventing oil-fouled sensors and intercoolers on turbocharged and supercharged engines.

Mild Versus Wild Capacity

Mild catch can kits use a smaller AN fitting size, typically 6AN or 8AN, sized for stock to moderately modified engines. Wild catch can kits step up to 8AN or 10AN fittings rated for 800 to 1000-plus horsepower builds where oil vapor volume is significantly higher.

Supercharged HEMI Platforms

The Dodge Challenger and Charger Hellcat, Jeep Grand Cherokee Trackhawk, and Dodge Durango Hellcat share the supercharged 6.2L HEMI engine and are among the most popular catch can applications in this collection, with billet radiator and fender-mount designs engineered around each platform's specific engine bay layout.

Ram 1500 TRX Applications

The Ram 1500 TRX shares the same supercharged 6.2L HEMI and uses a strut brace mounting design for its catch can, available in both mild and wild AN fitting configurations to match the truck's power level.

GM Platforms

Chevrolet Corvette C7, Camaro Gen 6, and Cadillac CTS-V and ZL1 catch cans mount to the radiator support or water pump area depending on platform, with mild and wild capacity options covering everything from stock LT engines to boosted or built applications.

Non-Supercharged HEMI Applications

Standalone 5.7L and 6.1L HEMI catch cans serve Dodge and Chrysler platforms without the supercharged Hellcat engine, addressing the same PCV blow-by and carbon buildup concerns on the naturally aspirated HEMI family.

Jeep Grand Cherokee and Durango V6 and V8 Applications

The Jeep Grand Cherokee and Dodge Durango share catch can fitment across their 3.6L V6 and 5.7L or 6.4L V8 engine options, with model-year-specific brackets to account for engine bay differences between generations.

Direct-Fit Versus Universal Mounting

Direct-fit catch cans use platform-specific brackets that mount to the radiator, fender, water pump, or strut brace without drilling, while universal catch cans require custom bracket fabrication for platforms outside the direct-fit lineup.

Materials and Construction

Billet aluminum construction resists corrosion and provides a durable mounting point for AN fittings, with most premium catch cans including a sight gauge or drain valve for easy oil level inspection and drainage.

AN Fitting Sizing by Horsepower

Higher horsepower and higher boost applications move more crankcase blow-by volume, which is why wild kits step up to larger AN fittings. Undersizing a catch can's fitting on a high-horsepower build restricts PCV flow and can cause crankcase pressure issues.

How to Choose the Correct Oil Catch Can

• Confirm the exact year, make, model, and engine displacement
• Choose mild capacity for stock to moderately modified engines
• Choose wild capacity for engines producing 800 horsepower or more
• Verify AN fitting size matches your PCV line routing
• Confirm mounting bracket location clears your specific engine bay layout
• Check for a sight gauge or drain valve for easier maintenance
• Verify billet aluminum construction for long-term corrosion resistance
• Confirm hose and fitting inclusion versus separate purchase requirements
• Check local emissions requirements before modifying PCV routing
• Plan a regular drain interval based on your driving and boost level

Common Questions

What does an oil catch can actually do?

An oil catch can intercepts oil vapor and blow-by gases from the PCV system before they recirculate into the intake tract, reducing carbon buildup on intake valves and protecting sensors and intercoolers from oil contamination.

How do I know if I need a mild or wild catch can?

Mild kits with 6AN or 8AN fittings suit stock to moderately modified engines. Wild kits with 8AN or 10AN fittings are sized for engines producing 800 horsepower or more where oil vapor volume is significantly higher.

How often do I need to drain a catch can?

Drain intervals depend on driving style and boost level, but most owners check and drain their catch can every oil change or every 3,000 to 5,000 miles for boosted applications.

Are oil catch cans legal?

Catch can legality depends on local emissions regulations and how the PCV system is routed. Confirm your local requirements before modifying factory PCV routing.

Will a catch can void my warranty?

Modifying factory PCV routing may affect warranty coverage on the affected components depending on manufacturer policy. Check with your dealer or warranty provider before installing.

Do I need one catch can or two?

Some V8 and V6 platforms route PCV from multiple points and use a dual-can setup, while others consolidate blow-by into a single line served by one catch can. Check your specific platform's kit configuration.

Can I install a catch can myself?

Most direct-fit catch can kits are DIY friendly for enthusiasts comfortable with basic hand tools, since brackets are pre-made for the specific mounting location on your platform.

What is the difference between billet and universal catch cans?

Billet aluminum catch cans with platform-specific brackets mount without drilling or fabrication, while universal cans require the owner to fabricate a custom mounting bracket.

Does a catch can improve performance?

A catch can does not add horsepower directly, but it reduces carbon buildup on intake valves over time, which helps maintain factory airflow and combustion efficiency on direct-injection engines.

What AN fitting size is standard for a Hellcat catch can?

Most Hellcat, Trackhawk, and Durango mild kits use 8AN fittings, while wild capacity kits for the same platforms step up to 10AN for higher-horsepower builds.
