S&S Cycle Replacement Crankcase Breather Hose for 1991-2006 Harley-Davidson Big Twin Sportster Buell
When crankcase pressure builds unchecked, engine performance suffers and longevity pays the price. A deteriorating breather hose quietly undermines everything your S&S carburetor was built to deliver. Swapping in a direct-fit S&S Cycle replacement restores proper crankcase ventilation so your engine runs cleaner, breathes free, and stays protected mile after mile.
