Supertech Performance HIVN-1003 High-Performance Engine Valve

Supertech Performance brings over 20 years of precision manufacturing experience to their engine valve lineup. Through intensive testing and close collaboration with professional engine builders, Supertech continuously refines their valves to deliver superior flow rates, durability, and quality for every application. The HIVN-1003 is sold per valve — order the exact quantity your engine requires.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for maximum strength and reliability. Supertech primarily uses EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloy grades and heat treatments available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Designed for exhaust valves subjected to extreme heat, making this material ideal for turbocharged and supercharged engine builds where temperatures exceed the limits of standard stainless steel.

Coating Technologies:

• Chrome Coating: A widely used treatment in performance valve applications, providing a hard, wear-resistant surface finish.
• Black Nitride: A surface-hardening treatment that produces a smoother finish than chrome, resulting in reduced friction between the valve stem and guide for improved longevity and performance.

Supertech Performance valves are engineered to meet the unique demands of each engine configuration. Whether building a naturally aspirated street engine or a high-boost forced induction application, Supertech offers the material and coating combination to match the job.
