DETAILS

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
  • Increases intercooler efficiency
  • Reduces carbon buildup
  • Includes CNC machined fittings
  • Includes PERRIN Turbo Sump Pump Restrictor
  • Includes a custom purpose built crankcase fitting
  • Includes all necessary hardware

Best possible reliability mod

I this will keep your car running reliabily in the long term especially when adding power. The inclusion of the turbo sump restrictor makes running aftermarket exhausts less prone to burnning a slight amount of oil. Overall recommended for anyone and everyone. Even if installation can be a little tricky.

Neat product

Haven't had any issues. The install was a bit difficult or more like frustrating. Wish the hoses came with adequate fitting so it didn't look like such a backyard jimmy rigg setup. No leaks so far and pretty satisfied with the product.
