GSC P-D Honda B/K/H Viton 6mm Exhaust Valve Stem Seal Set

GSC Power Division is known for making solid valvetrain components for performance builds. This set of exhaust valve stem seals is designed for Honda B-series, K-series, and H-series engines. Their main job is to prevent oil from leaking down the valve guide into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.

These seals are made from Viton, a material that holds up well to heat and the stresses of engine operation. They feature a 6mm stem size, which is common for many Honda performance applications. Replacing old, hardened, or cracked valve seals is a key step when you're rebuilding the top end of your engine to ensure it runs cleanly and efficiently.
