Moroso 85481 1999-2018 GM Truck Air/Oil Catch Can Separator

• Plumbed into a vehicle's PCV system to capture the excess crankcase vapors, residual oil mist and moisture from reentering the intake tract
• Vehicles from the factory vent these excess crankcase vapors, residual oil mist and moisture right back into the intake manifold which could cause detonation, oil deposits to form in the intake tract including the valves themselves and from lowering the efficiency of the intercooler in intercooler equipped vehicles
• Increases engine performance from cleaner intake air
• Air-Oil Separators have billet aluminum bodies with internal baffling and mesh media
• Includes heavy duty brass inlet and outlet fittings, Fuel/Emission/PCV Vapor hose, stainless steel mounting bracket and billet aluminum mounting clamp for the body of the separator
• Some Vehicle crankcase ventilation systems require that 2 Air-Oil Separator bodies be used to properly capture and ventilate the system
