Supertech Performance VWEVN-1034 Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Developed through rigorous testing and close collaboration with professional engine builders, Supertech valves deliver continuous improvements in flow, durability, and quality — making them a trusted choice for a wide range of performance applications.

Supertech recognizes that every engine has unique demands. To meet those demands, their valves are available in multiple materials and finish options suited to both street and high-performance builds.

Available Materials:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. Primarily used for intake and exhaust valves, with additional alloy options and heat treatment variations available for specific applications.
• Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating under extreme heat conditions, such as those found in turbocharged or supercharged engines.

Coating Options:

• Chrome Coating: A widely used finish in performance valve applications, offering proven durability and 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 that matches your engine's total valve count (e.g., order 16 for a 16-valve engine).
