Feuling - Red Cylinder Head Breathers fits '18 & Up M8 Harley Models

These cylinder head breathers are constructed from billet 6061 aluminum with square surfaces, guaranteeing outstanding umbrella valve sealing and longer main breather exit nipples with dual O-rings to deliver improved breather system sealing. The location of the properly sized breather inlets make for optimum engine breathing, and the special design strengthens breather volume and allows for easy serviceability. The breather bodies have multiple drain ports located on the inside floor. These ports are chamfered on ID to allow easy drainage but are squared off on exits to deter filling from splash oil. They come to you in an anodized fueling red and feature billet breather housings, billet covers, breather filter elements, umbrella valves and quality hardware. Fueling breathers will hold an engine vacuum; testing shown on a healthy engine will see a 3-4 oz. of oil in the sump. Once the dipstick is removed, another 3-4 oz will drain. Made in the U.S.A.

NOTES: The test procedure mentioned above can only be performed with a sealed engine meaning no external venting via dipstick or trans top cover. Breathers CAN be used with external venting via dipstick, trans cover and air cleaner. 1 Year warranty with option for an additional year if warranty form is filled out on website.
