Supertech Exhaust Valve 30.15mm Nissan RB26DETT

We manufacture our racing valves using only the highest quality materials available. We have spent countless hours studying these different materials as well as you applications to create just the right valve. Because of thermal fatigue the proper choice of material will greatly determine the valve performance and reliability. Supertech relentlessly test new materials to provide valves with unsurpassed fatigue resistance. These Inconel valves are a nickel base super alloy material that are used for exhaust valves in engines that reach very high temperatures, such as applications with turbo and superchargers.
