Tomei Racing Valves for 4G63 Evo/ DSM (TA303A-MT01A)
The Tomei racing valve set for the 4G63 DSM and Evo 1-9 models are ideal for high horsepower and racing. The oversized head diameter is tailored for each application to significantly improve flow rate. The waisted stem increases the volume of air and gases entering and exiting the combustion chamber as the valve extends. Each valve is precision-machined for the specific engine or application. The head, face, stem, and lock groove designs are optimized to enhance sealing performance, efficiency, and durability.
