Supertech Honda NSX 30.00 x 5.46 x 111mm Inconel Chromed Exhaust Racing Valve - Set of 12

These Supertech Inconel exhaust valves are built with a specific material choice in mind: Inconel. This high-nickel, high-chromium alloy is chosen for its exceptional strength and resistance to extreme temperatures, making it ideal for the demanding environment inside a high-performance engine's exhaust ports. Each valve in this set measures 30.00mm in diameter, has a 5.46mm stem, and a total length of 111mm, precisely matching the specifications for the Honda NSX. This set includes 12 valves, enough to service a complete engine.

The choice of Inconel isn't just about heat resistance; it also offers superior durability under high cylinder pressures and aggressive combustion cycles. The valves are also chromed, which adds another layer of surface hardness and helps reduce friction against the valve guides. This combination of advanced material and surface treatment aims to ensure consistent performance and longevity, even when your NSX is pushed to its limits. When rebuilding or upgrading the top end of your Honda NSX, using valves specifically designed for its engine architecture and built from materials that can handle the heat and stress is crucial for reliability and performance.

This set is intended for performance applications where engine internals are being upgraded. Ensure you consult your engine builder or a qualified mechanic to confirm compatibility with your specific build and to obtain the correct installation procedures, as these are performance parts and may require specific clearances or assembly techniques.
