Moroso 85713 Air Oil Separator Harley Twin Cam Stock Air Cleaner Polished

Moroso Performance Products has been manufacturing oiling systems and oil system accessories for over 50 years, and the 85713 air-oil separator/catch can system is specifically engineered for Harley-Davidson Twin Cam engines equipped with stock air cleaners. This polished aluminum separator fits 1999-2017 Harley Twin Cam models with stock air cleaners, providing superior crankcase vapor management and engine protection.

Key Features:

• Keeps the H-D cylinder head breather system fully functional while filtering out crankcase vapors, oil mist and condensation
• Two-piece body unscrews for easy cleaning and service
• Does not vent to atmosphere like other breather kits, keeping oil in the canister and off your bike
• Separates vapors from your engine while clean filtered air re-circulates back into the intake
• Polished billet aluminum construction for premium appearance
• Proudly made in the U.S.A.

This system keeps your air filter, throttle body, intake, pistons and valves free of excessive oil and carbon build up. By plumbing in-line of the breather system, it filters excess crankcase vapors, exhaust vapors, residual oil and moisture before re-entering the engine, reducing detonation and knock. The separator should be drained as a service item at oil changes and normal service intervals.
