Feuling External Breather Kit For Harley Big Twin 1993-2026

Feuling External Breather Kit For Harley

This kit allows the Feuling air cleaner backing plate to be converted from standard intake breathing to external breathers. In house testing, at Feuling shows venting the air cleaner to atmosphere may be problematic resulting in oil carry over/misting out of the breathers. When air filter venting is accompanied with the use of oil tank venting such as the Feuling vented dipstick and or a vented transmission top cover the oil carry over/misting can be increased. The overall health of the engine including the internal cylinder head breathers, oiling system and piston ring/cylinder seal play a major role with oil blow by, carry over and misting out of the breathers. Feulings testing shows the M-Eight engine has limited internal vacuum and the cylinder head breathers prefers the vacuum pull of the intake.
