What This Part Helps Address

Installation Notes and Tips

Clean both mating surfaces before installation and remove all old gasket material, carbon buildup, and corrosion. Verify the gasket style against the vehicle-specific notes in the fitment data, since some applications use a valve-to-adapter design while others use a 2.875-inch bolt center-to-bolt center EGR tube gasket. Confirm the vehicle year, make, and model before ordering, especially on Chevrolet and GMC trucks, vans, and compact cars.
