What this gasket helps address

• Exhaust leaks at the pipe-to-manifold joint
• Leakage at a worn or damaged flange seal
• Noise from escaping exhaust gases
• Soot marks around the exhaust connection
• Loss of sealing after gasket heat cycling

Installation notes and tips

Confirm the flange style, bolt-hole count, inside diameter, and application notes before installation. Clean both sealing surfaces thoroughly and inspect the mating flange for warping, corrosion, or pitting that could affect the seal. Verify the replacement against the OE reference 97188685 and the vehicle-specific exhaust connection location before assembly.
