Supertech Performance BMEVI-1030S High-Performance Engine Intake/Exhaust Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Developed through intensive testing and close collaboration with professional engine builders, Supertech valves are engineered for high flow rates, exceptional durability, and consistent quality across a wide range of performance applications.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. EV8 stainless is Supertech's primary alloy for both intake and exhaust valves, with additional alloys and heat treatment options available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Designed for extreme-heat exhaust applications such as turbocharged and supercharged engines, where standard stainless steel alloys may be insufficient.

Available Coatings:

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

Sold individually — one valve per unit. When ordering for an engine requiring multiple valves (e.g., 16-valve engine), set your order quantity accordingly.
