Killer B FA20 WRX Air/Oil Separator w/ Plumbing

The Killer B Motorsports Complete Air Oil Separator System is designed to prevent harmful oil contaminants from entering the intake system of the FA20 engine. It removes oil in both liquid and vapor form from vented crankcase gases using a vacuum source from the turbo inlet. The function is not affected by turbo size. It features billet and TIG-welded 6061-T6 aluminum construction. The collected oil drains back into the crankcase. It applies vacuum to the crankcase, improving ring seal, reducing oil consumption, and improving power potential. No media to clean or replace, and no baffles to inhibit crankcase flow. Includes Killer B Motorsport push-lock barb fittings and motorsport-grade hoses. Made in the U.S.A. with a lifetime warranty.
