Supertech Performance VWIVN-1027 Engine Intake or Exhaust Valve

Supertech Performance brings over 20 years of manufacturing expertise to the VWIVN-1027, a precision-engineered engine valve designed for demanding performance applications. Developed through intensive testing and close collaboration with professional engine builders, Supertech valves deliver exceptional flow rates, long-term durability, and consistent quality across a wide range of builds.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. Supertech primarily uses EV8 (21-4N) stainless for both intake and exhaust valves, with additional alloys and heat treatments available for specialized applications.
• Inconel 751 Nickel Base Alloy: Designed for extreme-heat exhaust applications, including turbocharged and supercharged engines where standard stainless alloys may be insufficient.

Coating Technologies:

• Chrome Coating: A widely used finish in performance valve applications, providing added surface hardness and heat resistance.
• Black Nitride Treatment: A surface-hardening process that produces a smoother finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Sold individually — one valve per unit. Order the quantity equal to the number of valves required by your engine. For example, a 16-valve engine requires a quantity of 16.
