Supertech Performance SIVN-1014-2 High-Performance Engine Intake/Exhaust Valve

Supertech Performance brings over 20 years of precision manufacturing expertise to the SIVN-1014-2 engine valve. Engineered through intensive testing and close collaboration with professional engine builders, this valve delivers the high flow rates, durability, and dimensional consistency demanded by performance and racing applications.

Material Options & Construction:

• One-Piece Forged Stainless Steel — Manufactured primarily from EV8 (21-4N) stainless alloy for superior strength and long-term reliability. Additional alloys with specialized heat treatments are available for application-specific requirements.
• Inconel 751 Nickel-Base Alloy — Used for exhaust valves subjected to extreme temperatures, making this material the preferred choice for turbocharged and supercharged engine builds where heat resistance is critical.

Protective Coatings:

• Chrome Coating — A widely adopted finish in performance valve manufacturing, providing enhanced surface hardness and wear resistance.
• Black Nitride Treatment — A surface-hardening process that produces a smoother finish than chrome, reducing friction between the valve stem and guide for improved longevity and performance.

Sold Per Valve. Order the quantity that matches your engine's total valve count. For example, a 16-valve engine requires a quantity of 16.
