About This Product
S&S standard steel breather valve. It fits 1948 to early 1977 Big Twin engines. The breather holes are elongated. They pull more oil from the cylinder heads by increasing vacuum duration. Use it with steel breather valve spacers only. Never mix steel and plastic breather parts. It suits Panhead and Shovelhead motors. It replaces OEM 25313-73. Check your spacer material before fitting. Sold individually.
Manufacturer part number: 33-4246.
