When you increase your intake flow, you must balance it with an equally capable exhaust system. The Ferrea +1mm Competition Plus Exhaust Valve set for the Mitsubishi 4G63/4G63T is the perfect match for your high-performance cylinder head. With a 31.5mm diameter, these valves allow for rapid evacuation of exhaust gases, reducing backpressure and helping your turbo spool faster.
These valves are precision-engineered to operate under the intense heat and pressure found in high-boost 4G63 engines. The Competition Plus alloy offers superior heat dissipation, preventing valve burning and ensuring a long service life even under extreme racing conditions. The 20-degree Flo design is optimized to maintain high gas velocity, which is essential for maintaining power in turbocharged applications. By pairing these with our +1mm intake valves, you create a balanced, high-efficiency valvetrain that can handle significantly more power than stock components. Don't compromise your engine build with stock-sized valves when you can have the performance of Ferrea. Enhance your engine's reliability and power potential today. Find all your performance engine parts at GGCRACING.
