This gasket seals the exhaust joint at the oxygen sensor connection, helping prevent exhaust leaks at that flange.

  • Inside diameter: 3/4 in
  • Bolt-to-bolt length: 1-11/16 in
  • Packaging: boxed; one gasket per application on the listed vehicles

Signs the original gasket may need replacing include a ticking or hissing exhaust noise and the smell of exhaust fumes near the joint. If a failed gasket at this connection is the cause, this part replaces it. Replacing the gasket whenever the joint is opened helps restore a clean seal.
