Product Details

The Supertech Performance VWEVI-1034F is a high-performance exhaust valve engineered for demanding applications. Built on over 20 years of manufacturing expertise, this valve delivers exceptional flow rates, durability, and quality through intensive testing and collaboration with professional engine builders.

Construction and Materials:

  • One-piece forged stainless steel design for maximum strength and reliability
  • Premium EV8 (21-4N) stainless alloy construction with application-specific heat treatment
  • Precision-engineered valve stem and face geometry for optimal flow characteristics

Advanced Coating Options:

  • Chrome Coating: Widely used in performance applications for enhanced wear resistance
  • Black Nitride Treatment: Advanced hardening process that creates a smoother surface than chrome, reducing friction between stem and guide for improved performance and longevity

For extreme high-temperature applications such as turbocharged or supercharged engines, Supertech also offers Inconel 751 nickel-base alloy valves that withstand elevated exhaust temperatures.

Important: This valve is sold individually. When ordering for a complete engine rebuild, multiply the required quantity by the number of exhaust valves needed for your application.
