Supertech Performance FIVN-1035 High-Performance Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to their line of high-performance engine valves. Developed through intensive testing and close collaboration with professional engine builders, the FIVN-1035 delivers exceptional flow rates, durability, and precision quality for demanding applications.

Supertech recognizes that every engine has unique performance requirements. To meet those needs, their valves are available in a range of premium materials:

Stainless Steel (EV8 / 21-4N Alloy)

• One-piece forged construction for maximum strength and reliability
• Primarily uses EV8 (21-4N) alloy for both intake and exhaust valves
• Additional alloys and specialized heat treatments available for specific applications

Inconel 751 Nickel Base Alloy

• Designed for exhaust valves operating at extreme temperatures
• Ideal for forced-induction applications including turbocharged and supercharged engines

Protective Coatings

To combat the effects of high heat, Supertech applies one of two industry-proven coatings:

• Chrome Coating — Widely used in performance valve applications for enhanced surface hardness and wear resistance
• Black Nitride Coating — A precision hardening treatment that produces a smoother surface finish than chrome, reducing friction between the valve stem and guide for improved longevity

Sold individually — per valve. Please order the exact quantity required for your engine build. For example, a 16-valve engine requires a quantity of 16.
