789138 O Ring 017 676 ID X 816 OD Black

This black O-ring is a vital sealing component for the S&S X-Wedge intake system, specifically designed for use with the single bore tuned induction setup. Measuring .676 inches ID by .816 inches OD, it provides a precise seal for the intake runners and adapter brackets. It is compatible with the entire X-Wedge engine family, including the X114, X117, and X121, as well as the larger big bore upgrades. These engines are frequently found in custom motorcycles like the Big Dog and Morgan 3 Wheeler. A high-quality O-ring is essential to prevent vacuum leaks, which can lead to poor throttle response and decreased performance. Sold individually, this O-ring ensures your tuned induction system maintains the airtight seal required for maximum torque and horsepower gains.
