Ferrea Mitsubishi 4G63/4G63T 6.55mm Viton Hi-Temp Exhaust Valve Stem Seal - Set of 8

These 6.55mm Viton exhaust valve stem seals from Ferrea are built to handle the high temperatures found in Mitsubishi 4G63 and 4G63T engines. Viton is a well-known material for its excellent resistance to heat and oil, which is crucial for keeping oil from leaking past the valve guides and into the combustion chamber.

When you're rebuilding the top end of your 4G63 or 4G63T, replacing these seals is a smart move to ensure proper engine sealing and prevent oil consumption. Ferrea is a popular name in performance engine components, and these seals are made to fit right into your stock or modified cylinder head.

This set includes eight seals, enough for a full set of exhaust valves on your engine. Make sure to check your specific application's requirements, but these are designed for the common 6.55mm valve stem size found on these Mitsubishi engines.
