Race Spec +1mm Intake/Exhaust Valve Set Mitsubishi Evo 8/9 2003-2006 | TOMTA303A-MT01A

These are the Tomei Racing Valves designed to handle the perils of high-performance driving conditions. Tomei has designed these valves with waisted stem which allows a greater volume of air and gases to enter and exit the combustion chamber as the valve extends.

Each valve has been designed and precision machined specifically for your application. The head, face, stem, and the lock groove have been optimized to ensure proper sealing, efficiency, and durability. Tomei manufactures their intake valves from SUH35 heat-resistant steel, and they are coated to improve resistance to heat, wear, and corrosion. The exhaust valves are made from Inconel 751 nickel-based alloy materials and can withstand temperatures of up to 1000° C.
