Supertech Performance BMIVN-1045S High-Performance Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Built through rigorous testing and close collaboration with professional engine builders, the BMIVN-1045S delivers the high flow rates, durability, and precision quality that demanding applications require.

Material Options:

• 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 alloy options and heat treatment variations available for specific engine applications.
• Inconel 751 Nickel Base Alloy: Engineered for exhaust valves operating under extreme heat conditions, including turbocharged and supercharged applications where standard materials would be insufficient.

Coating Technologies:

• Chrome Coating: A widely used surface treatment for performance valves, providing enhanced durability and heat resistance.
• Black Nitride Coating: A hardening surface treatment that produces a smoother finish than chrome, resulting in reduced friction between the valve stem and guide for improved longevity and performance.

Important: Supertech valves are 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.
