What It Helps Address

Installation Notes and Tips

Confirm the flange pattern, inside diameter, and bolt spacing before installation. Clean both mating surfaces thoroughly so the gasket seats evenly, and inspect the flange for warping, corrosion, or pitting that could affect sealing. Verify the vehicle position listed for your application, since this gasket is cataloged for front, rear, front left, and front right locations depending on the vehicle.

Quality Assurance

AP Exhaust 8480 is cataloged with exact dimensional data to support proper exhaust fitment on the listed applications. Use the part number 8480 and the vehicle position details to confirm the correct gasket before installation.
