Supertech Performance NIVN-1007-GTIR Intake Valve

The Supertech Performance NIVN-1007-GTIR is a high-performance intake valve engineered for demanding applications. Built on over 20 years of manufacturing expertise, this valve delivers exceptional flow characteristics, durability, and precision quality for engine builders and performance enthusiasts.

Construction and Materials:

• One-piece forged stainless steel design for maximum strength and reliability
• Manufactured primarily from EV8 (21-4N) stainless alloy with application-specific heat treatment
• Precision-engineered valve stem and head geometry for optimal flow
• Available with advanced surface treatments for enhanced performance

Surface Treatment Options:

• Chrome Coating: Proven performance valve coating widely used in high-output applications
• Black Nitride: Advanced hardening treatment that creates a smoother surface than chrome, reducing friction between the valve stem and guide while improving wear resistance

Application Notes:

Supertech designs each valve with specific engine requirements in mind, ensuring proper metallurgy and geometry for the intended application. For extreme temperature applications such as turbocharged or supercharged engines, Supertech also offers Inconel 751 nickel-base alloy exhaust valves.

Important: This valve is sold individually. When ordering for a complete engine, calculate the total number of intake valves required and order accordingly (e.g., for a 16-valve engine with 8 intake valves, order quantity of 8).
