Perrin Air Oil Separator Kit Black 2013-2023 BRZ / 2022-2023 GR86 / 2013-2016 FRS

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

The PERRIN Air Oil Separator is not a catch can. Catch cans capture engine blow-by and stores it in a container, which requires constant attention and removal of oil every few hundred miles. The air oil separator separates the oil from the air, draining it back to the engine, which eliminates the need for constant attention and draining of oil. As oil drains from the bottom of the PERRIN Air Oil Separator, clean oil-free air vents out of the top to rejoin the intake tract.

FEATURES:

• Not A Catch Can - The air oil separator separates the oil from the air while draining it back to the engine
• 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
