Perrin Performance
PERRIN Air Oil Separator for 2002-2021 Subaru WRX / 2004-2021 STI - Black (PSP-ENG-620BK)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2002-2021 Subaru WRX and 2004-2021 Subaru WRX STI.
Protect your turbocharged boxer engine from the harmful effects of oil vapor with the PERRIN Air Oil Separator (AOS). This system solves the common issue of blow-by gases entering the intake tract, which can coat intercooler fins, reduce effective octane levels, and lead to power-robbing detonation. Unlike standard catch cans that require constant monitoring and manual draining, the PERRIN AOS features a maintenance-free design that separates oil from air and returns it directly to the engine crankcase.
- Engine Longevity: Prevents carbon buildup on intake valves and maintains combustion efficiency by keeping oil out of the air-fuel mixture.
- Heated Canister: Integrates into the vehicle's coolant system to heat the AOS body, preventing water vapor and oil from emulsifying into sludge during cold weather operation.
- Baffled Design: Utilizes a multi-stage separation process to ensure clean air is recycled into the intake while oil is recovered.
- Premium Construction: CNC machined from 6061 aluminum and finished in a durable black texture powder coat.
- MPN: PSP-ENG-620BK
