Good To Know

Q: Do I need to replace this gasket every time the exhaust cover is removed? A: Yes, gaskets are single-use sealing components and should be replaced each time the cover is removed to prevent leaks. Reusing an old gasket risks exhaust and water leaks at the mating surface.

Q: Is this gasket sold as a single piece? A: This listing is for one outer exhaust cover gasket. Check your parts diagram if your service requires additional gaskets or seals for the same job.

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