Tomei Racing Valves for FA20DIT VA Subaru WRX (TA303A-SB04A)
The Tomei racing valve set for the VA WRX are designed to withstand high horsepower and allow greater flow of the FA20DIT engine. The oversized head diameter is tailored for each application, significantly enhancing flow rate. The waisted stem allows more air and gases to move in and out of the combustion chamber as the valve opens. Each valve is precision machined for its specific engine/application. The head, face, stem, and lock groove designs are optimized to improve sealing performance, efficiency, and durability.
