Increases engine performance from cleaner intake air

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
