Supertech Hi-Comp Flat Valve Set for H22A/H23A VTEC

Unlock the true potential of your H-series VTEC engine with the Supertech Black Nitrided Hi-Comp Race Flat Valve Set - a high-performance upgrade designed specifically for the H22A and H23A engines. Manufactured by Supertech, a trusted name in engine components, these valves are crafted from one-piece forged stainless steel using SAE EV8 (UNS S63008) for both intake and exhaust applications. The result is a robust valve set that stands up to intense pressure and high temperatures, ensuring consistent, reliable performance.

Supertech enhances these valves with tailored heat treatments to achieve the right balance of hardness and ductility, whether your focus is on street performance or heavy-duty racing. This means you can push your engine to its limits with confidence, knowing that your valves are engineered to handle the stress. If you own any JDM or US variants of the H22A, or the JDM H23A VTEC, this is your go-to valve upgrade to enhance air intake, optimize exhaust flow, and ultimately boost your engine’s efficiency and power output.

The two variants are split between Intake and Exhaust, so if you're looking for a full set, be sure to purchase both to have all 16 necessary for full assembly.
