Good To Know

Q: How many gaskets come with this listing? A: This listing is for the exhaust manifold gasket as described, so confirm the quantity you need against your machine before ordering. Ordering the correct count avoids a second trip when you reassemble the exhaust.

Q: Can I reuse my old manifold gasket? A: Exhaust manifold gaskets are not meant to be reused once compressed and heated, so replace it whenever the manifold is removed. A fresh gasket gives the best chance of a leak-free seal.

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