Why Choose Mishimoto?
Unlike traditional air-oil-separator (AOS) systems that can introduce heated vapors back into the engine, the Mishimoto Baffled Oil Catch Can does not rely on heat. It ensures that all blow-by, including low-octane oil and contaminated fuel vapors, condenses effectively within the can. Our catch can traps this harmful material and keeps it from circulating back into your oil system, ultimately safeguarding your engine's integrity.
Upgrade your engine protection and performance with the Mishimoto 18+ Audi B9 S4/S5 Baffled Oil Catch Can – because your vehicle deserves the best!
