Supertech Performance MIVN-1017 High-Performance Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to the design and production of their high-performance engine valves. Developed through intensive testing and close collaboration with professional engine builders, Supertech valves deliver continuous improvements in high flow rate, durability, and quality for every application.

Supertech recognizes that every engine has unique requirements and demands. To accommodate this, valves are available in a range of premium materials suited to any build — from naturally aspirated street engines to high-output forced-induction applications.

Available Materials:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Supertech primarily uses EV8 (21-4N) alloy for both intake and exhaust valves, with additional alloys and specialized heat treatments available for specific applications.
• Inconel 751 Nickel-Base Alloy: Used for exhaust valves subjected to extreme temperatures, making it ideal for turbocharged or supercharged engine builds where heat resistance is critical.

Surface Coatings:

• Chrome Coating: A widely used treatment in performance valves, providing excellent surface hardness and wear resistance.
• Black Nitride Coating: A hardening treatment that produces a smoother surface finish than chrome, resulting in reduced 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, order the exact quantity needed (e.g., order 16 for a 16-valve engine).
