Supertech Performance FEIVC-330-209 High-Performance Intake Valve

The Supertech Performance FEIVC-330-209 is a high-performance intake valve engineered with over 20 years of manufacturing expertise. Developed through intensive testing and close collaboration with professional engine builders, this valve delivers exceptional flow rate, durability, and precision quality for demanding performance applications.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. Supertech primarily uses EV8 (21-4N) alloy for intake and exhaust valves, with additional alloys and heat treatments available for specific application requirements.
• Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating under extreme heat conditions, including turbocharged and supercharged applications where conventional materials would fail.

Protective Coating Technologies:

• Chrome Coating: A widely used treatment in performance valve applications, providing an additional layer of surface protection and durability.
• Black Nitride Treatment: A surface-hardening process that produces a smoother finish than chrome, resulting in reduced friction between the valve stem and guide — ideal for high-RPM and high-heat environments.

Supertech recognizes that every engine has unique demands, which is why their valve lineup spans a broad range of materials and specifications to suit any build. Valves are sold individually (per valve) — order the exact quantity required for your application.
