Perrin Air Oil Separator Kit (AOS) Neon Yellow 2022-2024 WRX

The PERRIN Air Oil Separator prevents oil from entering the intake by capturing it from the crankcase vents. This reduces carbon-up, improves intercooler efficiency, and lowers the risk of performance degrading detonation. 

FEATURES:

• Not A Catch Can - The air oil separator separates the oil from the air while draining it back to the engine which eliminates the need for constant attention and draining of oil.
• Swirl Pot Technology - The multi-layer baffle design forces incoming engine blow-by to move rapidly across the baffles to separate oil from the engine blow-by
• Heated By Coolant - The base plate of the air oil separator is heated by coolant drawn from the engine which heats the entire air oil separator to the same temperature of the engine blow-by to reduce condensation
• Increased intercooler efficiency by Reducing the amount of oil deposited into the intercooler and intake system.
• Reduces carbon buildup
