Good To Know

Q: Should I replace this gasket every time the exhaust manifold is removed? A: Yes, exhaust manifold gaskets are single-use crush gaskets and should be replaced any time the manifold is unbolted to ensure a proper seal.

Q: Does this gasket require sealant during installation? A: This gasket is designed to seal on its own when the manifold is torqued to spec, though checking the mating surfaces for flatness before install is recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
