The WIX 17-1/2" x 13-5/16" OD air oil separator effectively separates air and oil to enhance engine performance and protection. It reduces the ingress of oil vapors and contaminants into the intake system, delivering improved filtration when compared to compact separators. Its optimal size plays a crucial role in preventing premature wear by maintaining cleaner engine components. Additionally, it contributes to lower oil consumption rates by effectively trapping excess oil vapor, supporting a cleaner engine operation.
