About This Product
This standard-size S&S steel breather valve is a high-quality replacement for 1948 to early 1977 Big Twin engines. S&S has engineered this valve with elongated breather holes to increase the duration of the vacuum, which helps pull more oil from the cylinder heads—a benefit for both stock and high-displacement builds. Because this is a steel component, it must be used with steel breather valve spacers; never mix steel and plastic breather parts. It is an excellent choice for maintaining proper crankcase pressure and oil scavenging in vintage Panhead and Shovelhead motors. This part is sold individually and corresponds to OEM number 25313-73.
Manufacturer part number: 33-4246.
