Upgrade the exhaust side of your Mitsubishi 4B11T engine with this set of eight GSC Power Division 23-8N Exhaust Valves. These valves are engineered to provide the perfect balance of strength, heat resistance, and flow for your Lancer Evolution or Ralliart build. Manufactured from high-grade 23-8N material, these valves are designed to withstand the extreme exhaust gas temperatures associated with high-boost turbo setups.
When increasing boost pressure, the exhaust valves are subjected to the highest thermal stress in the engine. Standard factory valves can often suffer from fatigue or burning, leading to catastrophic engine failure. GSC Power Division's 23-8N valves offer a significant upgrade in durability, ensuring that your engine can handle increased power levels reliably. The precision-machined 29mm head ensures a perfect fit with your existing valve seats, while the chrome-polished finish minimizes drag within the valve guide, promoting smoother operation at high RPMs. Whether you are preparing for a track day or a street-strip build, these valves provide the peace of mind you need. Optimize your engine's performance with quality components from GGCRACING.
