Maximize the exhaust flow of your Mitsubishi 4G63T engine with the GSC Power Division Chrome Polished Exhaust Valve. Designed specifically for the Evo 1-9 platform, these valves feature a 30.5mm head diameter, matching the standard size while offering significant improvements in surface finish and heat resistance. The chrome-polished surface reduces friction and helps prevent carbon buildup, ensuring consistent performance under high-load racing conditions.
In a high-performance 4G63T build, the exhaust valves are subjected to extreme thermal stress. GSC Power Division utilizes high-quality alloys that maintain structural integrity even when exposed to high exhaust gas temperatures (EGTs). The polished finish not only aids in flow efficiency but also provides a smoother surface that resists heat absorption better than standard cast valves. Whether you are building a stock-turbo setup or a high-horsepower big-turbo monster, these valves provide the durability and flow characteristics necessary to make power reliably. Replace your worn or damaged valves with these premium GSC components to restore your engine's performance. Find all your 4G63T engine internals at GGCRACING.
