The WIX air oil separator is designed with a 11-1/8" x 13-13/16" outer diameter to efficiently separate air and oil, promoting cleaner intake air. By minimizing contaminant buildup, it reduces engine wear and tear, thus maintaining engine health. Its large surface area is effective in capturing more contaminants, supporting consistent lubrication while preventing oil mist recirculation. This helps in maintaining a clean air-fuel mix, ensuring better engine function. The separator plays a crucial role in maintaining overall engine health and functionality.
