Supertech Performance BMEVN-1009 Engine Intake/Exhaust Valve

Supertech Performance brings over 20 years of precision manufacturing experience to their engine valve lineup. The BMEVN-1009 is engineered through intensive testing and close collaboration with professional engine builders, resulting in a valve that delivers exceptional flow rate, durability, and dimensional consistency for demanding performance applications.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. The EV8 alloy is the primary choice for both intake and exhaust valves, with additional alloy and heat treatment options available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Designed for extreme-heat exhaust applications, including turbocharged and supercharged engines where conventional stainless steel reaches its thermal limits.

Protective Coatings:

• Chrome Coating: A proven, widely-used finish in performance valve applications offering excellent wear resistance.
• 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 — one valve per unit. Order the quantity equal to the total number of valves required for your engine (e.g., order 16 for a 16-valve engine).
