The WIX 9-1/2" x 8-3/8" OD air oil separator efficiently separates oil from air, contributing to enhanced engine performance. It is constructed with durable materials designed to withstand harsh engine environments. It reduces emissions by capturing oil mist, which helps maintain a cleaner air output. It protects the engine's intake system by preventing oil contamination and buildup, thereby increasing engine lifespan by reducing wear caused by contaminated air intake.
