Specs At A Glance

Good To Know

Q: Do I need to replace valve seals at the same time? A: Yes, valve seals and guide checks are commonly done with an exhaust valve job, since the head is already apart. Reusing worn seals can cause oil consumption after the repair.

Q: Is this valve sold as a single unit? A: Yes, this listing covers one exhaust valve unless otherwise noted. Confirm your engine's cylinder count to order the correct quantity.

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