Feuling Cylinder Head Breathers for 2017-2023 Harley M8

Factory plastic OEM breathers can be problematic, we find the material easily distorts, especially after seeing excessive heat then the internal umbrella valve struggles to seal, causing oil carry over. FEULING Cylinder head breathers for M8 engines are machined from billet 6061 aluminum with square surfaces, promoting excellent umbrella valve sealing, longer main breather exit nipples with dual O-rings to promote better breather system sealing. Made in the USA
