Air Oil Separator M8 W/stock & Se Air Cleaners Polished

The moroso air-oil separator/catch can system keeps the h-d cylinder head breather system fully functional.It filters out crankcase vapors, oil mist & condensation that normally vent to the intake system.This will keep your air filter, throttle body, intake,pistons & valves free of excessive oil and carbon build up.Our system is different than others on the market.It separates the vapors breathing from your engine, collecting them in our air-oil separator/catch can system while clean filtered air re-circulates back into the intake.Once the air oil separator/catch can system fills, it will need to be drained as a service item.This also can be done at oil changes and normal service intervals.
