We manufacture our racing valves using only the highest quality materials available. We have spent countless hours studying these different materials as well as your 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 tests new materials to provide valves with unsurpassed fatigue resistance. These Inconel valves are a nickel-base superalloy material that is used for exhaust valves in engines that reach very high temperatures, such as applications with turbo and superchargers.
