The WIX 14" x 21" OD air oil separator efficiently removes oil mist from the air intake, ensuring cleaner engine air. It enhances engine performance by preventing oil buildup in the system and reduces emissions by capturing oil particles before they escape into the atmosphere. Additionally, it extends the lifespan of engine components by maintaining cleaner operation. Minimal airflow restriction ensures optimal engine performance levels are maintained, providing an effective solution for managing oil mist within the system.
