Walker Exhaust Oxygen Sensor Gasket P/N:31564
Keep exhaust gas flowing through the intended path with the AP Exhaust Oxygen Sensor Gasket (MPN 9291), a direct-fit replacement for a wide range of applications including the 2010-2013 Acura MDX, 1990-1997 Geo Prizm, 2016-2019 Honda HR-V, 2017-2020 Honda Ridgeline, and dozens of Toyota trucks and cars — see the Buyer's Guide tab for the full list. This gasket seals the exhaust joint at the oxygen sensor connection, helping prevent exhaust leaks at that flange.
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.
