Exclusive to Boise , Idaho based HardDrive , the Moroso air-oil separator / catch can system keeps the H-D cylinder head breather system fully functional by filtering out the crankcase vapors , oil mist and condensation that normally vent to the intake system . This will keep the air filter , throttle body , intake , pistons and valves free of excessive oil and carbon build-up . Headquartered near New Haven , Ct ., and with a specialty ignition wire manufacturing facility in Pa .,
Moroso Performance Products have been manufacturing oiling systems and oil system accessories for over 50 years . One of the world ' s most respected suppliers of automotive equipment for racing and street performance applications , Moroso manufactures over 4,000 products , from oil pans and oiling systems to ignition wire and
components , valve covers , fuel system equipment , air cleaners , hard core racing tools , chassis and suspension equipment and numerous other performance parts . The company has an impressive list of customers , ranging from grassroots racers to top level NASCAR and NHRA / IHRA race teams . Their air-oil separator / catch can system for Harley applications is different than others on the market . It separates the vapors breathing from the engine , collecting them in their air-oil separator / catch can system while clean , filtered air ( rather than contaminated air ) recirculates back into the intake . The system plumbs inline of the breather system . Once the air-oil separator system fills , it is simply drained as a service item . This can be done at oil changes and normal service intervals . The two-piece design simply unscrews for easy cleaning and service . The system does not vent into the atmosphere like other breather kits on the market - keeping the oil in the canister . It is available with a polished or black body for most H-D Twin Cam and M-8 Touring models and works with the stock and Screamin ' Eagle air cleaners and selected Vance & Hines V02 and S & S teardrop air cleaner and filter applications . For other and custom applications ( including 1991 - 2013 Sportsters ), Moroso offers a universal air-oil separator for air cleaners that do not bolt to the cylinder heads , or when factory breather bolts are not used with an air cleaner backing plate . All kits include the Moroso billet air-oil separator / catch can , mounting bracket and hardware , 6 ft of 3 / 8 " PCV compliant breather hose , two 3 / 8 " barbed inlet fittings and installation instructions . Moroso also offers high performance Ultra 40 spark plug wires as a stock upgrade for selected Touring ( 1980 to present ), Softail ( 1984 to present ), Dyna , FXR , XL ( 1986 to present ), Shovelhead and Street models .
