Moroso Air/Oil Separator (GM Truck 4.8/5.3/6.0 1999+ and Hummer H2 03-09) Moroso

The air/oil separator is plumbed into a vehicle’s PCV system to capture the excess crankcase vapors and the residual oil mist from reentering the intake track. 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 including the valves themselves.

• Polished Billet Aluminum body compliments any engine compartment and can be chromed or powder coated for a custom look
• Includes 3/8″ 90º inlet & outlet fittings, 36″ of 3/8″ rubber hose for plumbing the Air-Oil Separator inline, and a billet aluminum mounting clamp for the body of the Separator
• Features a bottom drain with elbow that makes draining the collected oil virtually mess-free
