Moroso 85723 Air/Oil Separator for Harley-Davidson Milwaukee Eight Touring - Black

The Moroso 85723 air/oil separator maintains the Harley-Davidson cylinder head breather system while filtering out crankcase vapors, oil mist, and condensation that would otherwise contaminate the intake system. This keeps your air filter, throttle body, intake, pistons, and valves free of excessive oil and carbon buildup.

Key Features:

• Separates engine vapors and collects them in the catch can while clean filtered air recirculates back into the intake
• Does not vent to atmosphere like other breather kits - keeps oil in the canister, off your bike, and off the ground
• Two-piece body unscrews for easy cleaning and service
• Round separator tank with 2.25-inch diameter
• Black finish complements most motorcycle aesthetics
• Proudly Made in the U.S.A.

The system plumbs inline of the breather system and filters excess crankcase vapors, residual oil, and moisture before it re-enters the engine, reducing detonation and knock while helping eliminate deposits in the intake tract. The catch can needs to be drained periodically as a service item, which can be done at oil changes and normal service intervals.

Application: Designed for Harley-Davidson Milwaukee Eight Touring models equipped with stock or Screaming Eagle air cleaners. Does not fit Heavy Breather air cleaners.
