Supertech Performance BMIVN-1006-L Engine Intake/Exhaust Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Engineered through intensive testing and direct collaboration with professional engine builders, Supertech valves deliver exceptional high-flow performance, long-term durability, and precision quality for a wide range of applications.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. Supertech primarily uses EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloys and heat treatments available for specialized engine applications.
• Inconel 751 Nickel-Base Alloy: Designed for extreme-duty exhaust valves in high-heat environments, including turbocharged and supercharged applications where standard alloys may not withstand sustained temperature exposure.

Coating Technologies:

• Chrome Coating: A widely adopted finish in performance valve applications, providing a hard, protective surface layer.
• 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 — Per Valve. Please order the exact quantity required for your engine build. For example, a 16-valve engine requires a quantity of 16.
