    The Moroso Air-Oil Separator is plumbed into a vehicle's PCV system and captures the excess crankcase vapors and the residual oil mist. These excess crankcase vapors and residual oil are re-entered right back into the intake manifold from the factory, which could cause detonation and oil deposits to form in the intake tract, including the valves themselves.

    Manufacturer's Part Number:

    These Moroso Air-Oil Separator Tanks are plumbed into a vehicle's breather/PCV system to capture excess crankcase vapors and the residual oil mist from re-entering the intake track. There are versions available for factory configurations, vacuum pumps, and universal installations.

    Vehicles from the factory vent these excess crankcase vapors and residual oil right back into the intake manifold, which could cause detonation and oil deposits to form in the intake track. Moroso's polished billet aluminum bodies complement any engine compartment and can be chromed or powdercoated for a custom look.
