Description
The Mishimoto Baffled Oil Catch Can, PCV Side (MMBCC-WRX-22P) is a direct-fit, billet 6061 aluminum catch can engineered specifically for the 2022+ Subaru WRX and its FA24DIT direct injection engine. Unlike heated air-oil separator systems that drain blow-by back into the oil pan, this catch can traps oily, low-octane vapor permanently in a removable canister, keeping it out of your engine oil for good.
Blow-by is an unavoidable byproduct of forced induction, and when pressurized gasses recirculate through the PCV system, oil particles ride along in that air, coating the intake system and intake valves. Over time this leads to carbon buildup on valves and can reduce octane levels in the combustion chamber by introducing oil into the air/fuel mixture. As air enters this Mishimoto catch can, it passes through a 50-micron bronze filter and an internal air diverter baffle, which creates turbulence to help capture oily particles and let them condense until they’re heavy enough to drip into the canister below. The result is cleaner air flowing back into your intake system and less carbon buildup on intake valves during combustion. For anyone researching parts of a car engine, components of an automobile engine, or how car engine parts manage blow-by and automobile combustion byproducts, a baffled oil catch can like this one is a practical, serviceable addition to a modern turbocharged car engine.
Vehicle Applications
This catch can kit is designed as a direct fit for the Subaru WRX equipped with the FA24DIT engine (chassis code VB).

Frequently Asked Questions
What vehicles is the Mishimoto MMBCC-WRX-22P catch can designed for?
It is a direct fit for the Subaru WRX with the FA24DIT engine (chassis code VB), covering the WRX Base for 2022–2024, the GT, Limited, Premium, Sport, and Sport-tech trims for 2022–2026, and the 2026 WRX High, Series.Yellow, Sportwagon, TS, and tS Performance trims.
How does this catch can filter oil from PCV blow-by?
Air entering the can passes through a 50-micron bronze filter and an internal air diverter baffle, which creates turbulence that helps oily particles condense and drip into the canister, leaving cleaner air to flow back into the intake system.
Is the Mishimoto catch can serviceable and washable?
Yes, the filter and can are fully serviceable and washable, and the can uses a twist-off design with a drain plug (3/8 – 18 NPT thread) included.
Does this catch can drain oil back into the engine oil pan?
No. Unlike heated AOS systems that drain blow-by back into the oil pan, this Mishimoto catch can is not heated, so blow-by condenses and is trapped in the can and kept out of the engine permanently.
What is included with the MMBCC-WRX-22P kit?
The kit includes one compact baffled oil catch can, one application-specific mounting bracket, two direct-fit hoses, two 1/2-IN aluminum barbed fittings, four worm gear clamps, mounting hardware, and the Mishimoto Lifetime Warranty.
What material is the catch can made from?
The can is made from 6061-T6 billet aluminum (listed as 6061 Aluminum in specifications) with a black anodized finish and CNC-machined aluminum fittings.
