Breather Kits & Parts

9 products

Complete crankcase breather systems and individual replacement parts for Twin Cam, Milwaukee-Eight, Evolution, and Sportster engines. Correct breather operation keeps oil out of the airbox and helps the intake make consistent power. We stock Feuling, Drag Specialties, and S&S — names well respected across the Softail, Dyna, Touring, and Sportster communities. From a simple reed-valve upgrade to a full head-breather kit, these are a proven way to clean up the motor.
