GSC P-D 4G63T Evo 1-9 / 90-98 DSM Viton 6.6mm Valve Stem Seal - Set of 500

This is a set of 500 Viton valve stem seals from GSC Power Division, specifically made for the 4G63T engine found in Mitsubishi Evo 1-9 and DSM models from 1990-1998. These seals are crucial for preventing oil from leaking past the valve guides and into the combustion chamber, which can cause blue smoke on startup, increased oil consumption, and fouled spark plugs.

Crafted from Viton, a high-performance fluoroelastomer, these seals are built to withstand the high temperatures and harsh conditions found in performance engines. The 6.6mm stem size ensures a precise fit on the valves for these specific applications. Having a full set of 500 means you'll have plenty for a complete engine rebuild, ensuring every valve guide is properly sealed for optimal engine performance and longevity.
