Good To Know

Q: Can I reuse my old exhaust manifold gasket? A: No, exhaust manifold gaskets are single-use and should be replaced any time the manifold is removed. Reusing one risks exhaust leaks.

Q: Does this require any sealant? A: Most exhaust manifold gaskets install dry with no sealant needed. Always torque manifold bolts to the manufacturer specification.

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