Description
Oil carryover from your breather is more than just a mess—it’s a sign your crankcase ventilation can’t keep pace with your Twin Cam engine. The S&S CYCLE Breather Valve eliminates this problem at the source, allowing your stock oil pump to breathe properly without coating your bike in oil. If you’re running a stock or upgraded cam setup, this bolt-on solution installs easily during routine maintenance and delivers the reliability you need.
