The PERRIN Air Oil Separator traps oil from the crank case vents before it enters the intake, reduces carbon build-up, increases intercooler efficiency, which reduces the chance of performance-robbing detonation.
FEATURES:
Not A Catch Can - Theair oilseparator 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 theair oilseparator is heated by coolant drawn from the engine which heats the entireair oilseparator to the same temperature of the engine blow-by toreduce condensation
