S&S Cycle Stock Manifold O-Ring 10-Pack for 1990-1999 BT and 1986-2003 Sportster

A deteriorated manifold O-ring allows air into the intake tract downstream of the carburetor, leaning out the mixture and producing surging, rough idle, or a hesitation that no jetting change will resolve. The S&S Cycle Stock Manifold O-Ring ten-pack keeps a supply of genuine replacement seals on hand so any air leak at the manifold interface can be corrected immediately.
