The WIX air oil separator measures 18-13/16 " by 3-1/8 " in outer diameter and is engineered to prevent oil mist from recirculating into the engine. This mechanism supports a cleaner air intake, which effectively reduces emissions, contributing to a more environmentally friendly vehicle. It enhances engine performance by maintaining a clean air-fuel mixture, which is vital for optimal engine function. Additionally, it maximizes the engine lifespan by minimizing abrasive oil wear on internal components. The compact design allows for integration into tight under-the-hood spaces.
