1-Liter Baffled Air Oil Separator

This unit maintains OEM PCV system functionality while adding capacity, drawing on years of testing in both standard and competition applications. The AOS features a 1-liter, cast aluminum swirl pot canister that effectively separates oil from PCV gasses before they return to the intake system. Its fully heated cast aluminum housing, superior venting capabilities, and unique patent-pending baffle design distinguish it from other systems. This AOS is compatible with all fuel types and standard ECU calibrations, contributing to extended engine life and improved crankcase ventilation. By preventing oil from entering the intake tract, it helps avoid premature mechanical failure, hose degradation, detonation, and other issues associated with oil contamination. The V3 Street Series AOS offers an upgraded heating system with coolant lines relocated to the bottom of the body for a cleaner installation and reduced condensation buildup. It includes a true 360-degree rotating breather port and dual breather ports for enhanced pressure stream oil separation. The product is made from cast aluminum and comes in a black finish.
