Unlock the full potential of your Mitsubishi 4G63 or 4G63T engine with these Ferrea Competition Plus exhaust valves. Engineered for high-RPM stability and extreme heat resistance, these 30.5mm valves are the gold standard for turbocharged performance builds. Whether you are running a street-strip setup or a dedicated track car, these valves ensure consistent flow and reliability.
The Competition Plus series features a specialized heat-treated alloy that resists deformation under high boost pressures. The 22-degree Flo design optimizes exhaust gas scavenging, reducing backpressure and allowing your turbocharger to spool faster. These valves are precision-machined to meet strict tolerances, ensuring a perfect seal against your cylinder head seats. By upgrading your valvetrain, you prevent valve float and potential engine damage during high-load conditions. Trust your engine's longevity to the best in the industry.
