GSC P-D Mitsubishi 4G63T Evo 1-9 Chrome Polished Exhaust Valve - 30.5mm Head (STD) - Single

This GSC Power Division exhaust valve features a 30.5mm head diameter, which is the standard size for many Mitsubishi 4G63T engines found in Evo 1 through 9 models. The valve itself is chrome polished, a finish that helps reduce friction as it moves within the valve guide and also offers some resistance to corrosion. These valves are built to handle the demands of performance engines, ensuring reliable operation under high temperatures and pressures.

When you're rebuilding the top end of your 4G63T, choosing the right valves is important for both performance and longevity. The chrome polishing on this particular valve not only contributes to a smoother operation but also helps maintain its surface integrity over time. It's a well-built component designed to be a direct replacement for your stock exhaust valve, making installation straightforward if you're already working on the cylinder head.
