The WIX 9-7/8" x 12" OD air oil separator efficiently removes oil mist, enhancing engine air quality and performance. It boosts engine longevity by keeping oil residue out of the intake system. It is designed for high airflow, ensuring minimal pressure drop and smooth engine operation. Its robust construction resists wear and tear from thermal stress. Additionally, it reduces emissions by preventing oil aerosols from re-entering engine air, making it a vital component in maintaining engine efficiency and environmental standards.
