GSC P-D Mitsubishi 4G63T Evo 1-9 Polished Super Alloy Exhaust Valve - 31.5mm Head (+1mm) - Single

This is a single GSC Power Division exhaust valve designed for Mitsubishi 4G63T engines found in Evo 1-9 models. It features a 31.5mm head, which is 1mm larger than stock, and is made from polished super alloy for improved durability and performance in high-stress engine builds. If you're rebuilding the top end of your 4G63T, these valves are a solid option for handling increased cylinder pressures and temperatures.

The super alloy construction offers better resistance to heat and wear compared to standard valves, especially important when pushing the limits of a turbocharged engine. The polished finish helps reduce friction as the valve moves within the guide, contributing to better sealing and overall engine efficiency. This specific valve is for the exhaust side and is a direct replacement for the stock size, but with the larger head diameter for potentially improved flow.
