The Mishimoto WRX oil catch can system is designed and engineered to work on your WRX to eliminate harmful blow by vapors from re-entering your engine. The EJ25 in the WRX is known for producing blow-by gases during normal to severe driving, especially when more boost and horsepower is added to the engine. This oil blow-by can work its way into your intake system, reducing the octane rating of your fuel and potentially causing detonation.
The WRX oil catch can system uses our two-port compact baffled catch can and three-port compact baffled catch can with bronze filters and internal baffles to better separate the oil from the crankcase vapors. The turbo inlet side of the kit utilizes our three-port baffled catch can to catch as much oil vapors as possible. The system also includes two direct-fit mounting brackets that are extremely easy to install and also fit right hand drive vehicles!
The WRX catch can system comes with six direct fit black hoses that fit as if they were stock. The hoses are designed to fit right onto the PCV valve ports and into the turbo inlet ports. Plastic, barbed fittings connect the hoses to the can. And, like every Mishimoto baffled catch can system, this WRX oil catch can system comes with our Mishimoto Lifetime Warranty!
Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.
