Supertech Performance GIVN-0012S High-Performance Engine Valve

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup, delivering products refined through intensive testing and close collaboration with professional engine builders. The GIVN-0012S is engineered for high flow rate, exceptional durability, and precision quality, making it a trusted choice for performance and racing applications. Supertech valves are sold individually (per valve) — order the exact quantity your engine requires.

Material Options:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. Supertech primarily utilizes EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloy and heat treatment options available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Designed specifically for exhaust valves subjected to extreme temperatures, such as those found in turbocharged or supercharged engines where heat management is critical.

Coating Technologies:

• Chrome Coating: A widely adopted finish in high-performance valve applications, providing excellent surface hardness and wear resistance.
• Black Nitride Treatment: A surface-hardening process that produces a smoother finish compared to chrome, resulting in reduced friction between the valve stem and guide for improved longevity and performance.

Supertech Performance designs each valve to meet the unique demands of individual engine builds, offering material and coating combinations to suit naturally aspirated, turbocharged, and supercharged powerplants. Order quantity should match the exact number of valves your engine application requires.
