Protect your engine’s efficiency and prevent costly emissions system contamination with this premium Volvo D13 Mack MP8 Separator by FleetPro Parts & Tires. Specifically engineered for Mack MP8 and Volvo D13 engines, this crankcase oil separator (also known as a centrifuge) plays a vital role in removing oil mist from crankcase gases before they are recirculated. A failing separator can lead to oil carry-over, which clogs your aftertreatment system and reduces overall engine performance.
