The WIX air oil separator measures 14-3/4 " by 14-7/8 " in outer diameter. This component is designed to separate oil mist from the air, contributing to improved engine performance. It plays a crucial role in protecting engine components by preventing oil contamination. Additionally, it enhances air quality through the removal of fine oil particles, ensuring optimal airflow for efficient engine operation. By capturing oil droplets, it helps to minimize environmental pollution, making it a vital part of engine maintenance and environmental responsibility.
