Supertech Performance HIVN-1022F High-Performance Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup, engineering each valve through rigorous testing and close collaboration with professional engine builders. The result is a product line built around high flow rates, exceptional durability, and consistent quality — designed to meet the precise demands of any performance application.

Supertech recognizes that every engine has unique requirements, which is why their valves are available in a range of materials and coatings to suit everything from naturally aspirated street engines to forced-induction race builds.

Available Materials:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. EV8 is Supertech's primary alloy for both intake and exhaust valves, with additional alloy options and heat treatments available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Used in exhaust valves subjected to extreme temperatures, making it the ideal choice for turbocharged and supercharged engine builds where heat management is critical.

Protective Coatings:

• Chrome Coating: A widely used finish in performance valve applications, providing a hard, wear-resistant surface layer.
• Black Nitride Treatment: A hardening process that creates a smoother surface finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Sold individually — one valve per unit. When ordering for an engine that requires multiple valves (e.g., 16 valves for a 4-cylinder with 4 valves per cylinder), order the exact quantity needed.
