PerformancePartsNOW presents…… Supertech Performance Valves and Components! This listing is for a complete set of 8 STD Supertech Black Nitride Exhaust Valves for Subaru Impreza WRX STi EJ20 EJ25 EJ257 EJ255 applications This listing includes Supertech part numbers: SEVN-1010-8 (Exhaust) SPECS Head Diam: 32.00mm(std) Material: Stainless Steel 23-8N Groove Type: Single Groove Length: 104.7mm(std) Stem Diam: 5.96mm Key Features One Piece Valves Durability Strict Dimensional Tolerances Superfinish Higher Flow Rates Materials Used One Piece Valves are not finished from generic blanks rather they are specifically designed for each and every application. Supertech strives to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. Stricter dimensional tolerances combined with finished seats with equally strict run out tolerances for better sealing, better performing and easier to install solution anywhere. In 2006, Supertech introduced stem Superfinishing as a standard addition to all valves at no additional cost. Superfinish combined with a Black Nitrided valve reduces the surface roughness to 1/3 of the chrome coated valve for unsurpassed performance and durability. Optimum high flow rates are achieved through manufacturing with the best angles for each application. Back cut, under cut and valve head angles per application are considered to produce the optimum high flow rates for each application. Supertech manufactures their racing valves using only the highest quality materials available. They 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. Steel, black nitride, sodium fill, iconel/nimonic alloy, titanium, titanium coating and molybdenum coating are all used in the production of Supertech valves. Valve Springs are computer designed and manufactured from Superclean Chrome Silicon Vanadium alloy for most applications. Chrome Silicon Vanadium Molybdenum+Ni are used in high stress applications. Beehive Springs are also available. Item images are representative and for reference only; images of actual product may differ. Product information, specifications and fitment should be verified with the manufacturer before purchasing. Supertech Performance Supertech Performance applies 30 years of experience in the development of each and every Supertech racing valve we sell. Combine this experience with state of the art equipment such as ultrasonic tests, x-rays, laser measurement equipment, and applications like computerized Finite Element Analysis (FEA) and it is no wonder why Supertech has some of the best performance products on the market. While this is more than most manufacturers, they do not stop there. They also do extensive testing working very closely with many of today’s top engine builders in order to continuously improve their products. All of this is meant to insure Supertech’s industry leading reputation for high flow rates, durability and uncompromising quality. **** International Customers are welcome **** FREE Shipping within the Continental 48 States Domestic We will ship anywhere in the United States, including Hawaii, Alaska and Puerto Rico.
