PERRIN PERFORMANCE AIR OIL SEPARATOR: 2022+ SUBARU WRX

PSP-ENG-611

Improve performance and maintain peace of mind for the 2022+ Subaru WRX platform by utilizing the PERRIN Performance Air Oil Separator (AOS). PERRIN's AOS functions by trapping oil from the crankcase vents before it enters the intake, reducing carbon buildup and increasing intercooler efficiency, reducing the chance of performance-degrading detonation. 

The PERRIN Performance AOS is not a catch-can. Catch-cans capture engine blow-by and store it in a container, requiring constant attention and oil removal every few hundred miles. The AOS separates the oil from the air, draining it back to the engine, eliminating the need for constant attention and draining of oil. Simultaneously it reduces carbon buildup in the combustion chamber, intake valves, and intake tract. As crankcase blow-by gets recirculated back to the intake to be ingested by the engine, it gets stuck and builds up over time which causes a loss in power and extra wear and tear on the valves. The AOS prevents this blow-by from accumulating in the intake tract, providing long-lasting performance. 

PERRIN Performance manufactures and supplies the finest Subaru products on the market today. From suspension to the engine, It makes products that will boost any Subaru's performance to the next level.

• Increases intercooler efficiency by reducing the amount of oil deposited into the intercooler and intake system
• Reduces carbon buildup in the combustion chamber, intake valves, and intake tract
• Features CNC machined fittings
• Powder Coat Finish: Black, Red, Neon Yellow
