Supertech Performance VWIVN-1011 Performance Engine Valve

Supertech Performance brings over 20 years of precision manufacturing experience to their engine valve lineup. Each valve is developed through rigorous testing and close collaboration with professional engine builders, ensuring continuous refinement and real-world performance gains. The result is a valve engineered for high flow rates, exceptional durability, and consistent quality across a wide range of applications.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. Supertech primarily utilizes EV8 (21-4N) alloy for both intake and exhaust valves, with additional alloy grades and heat treatment options available for specific application demands.
• Inconel 751 Nickel-Base Alloy: Engineered for extreme-heat exhaust applications, including turbocharged and supercharged engines where conventional stainless steel may fall short.

Coating Technologies:

• Chrome Coating: A proven, widely-used surface treatment for performance valves, adding hardness and resistance to wear.
• Black Nitride Treatment: A hardening process that produces a smoother surface finish than chrome, reducing 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 (e.g., 16 valves for a 4-cylinder), enter the required quantity at checkout accordingly.
