Supertech Performance HYEVI-5532 Inconel Racing Exhaust Valve

The Supertech Performance HYEVI-5532 is a high-performance Inconel racing exhaust valve engineered for Hyundai engines operating under extreme heat and high-boost conditions. Designed for street performance and competition use alike, this valve delivers superior durability and sealing where stock valves fall short.

Key Features:

• Inconel Construction: Manufactured from a nickel-based superalloy (Inconel 751 or Nimonic 80A) specifically chosen for its ability to withstand extreme exhaust gas temperatures
• One-Piece Forged Design: The valve head is forged in a slow two-step process to maintain optimal material grain flow for maximum strength and reliability
• Hardened Tip: Features a hardened valve tip for long-term wear resistance under continuous valve train load
• Superfinish Stem: Supertech's proprietary stem superfinishing treatment reduces surface roughness and friction for smooth operation and extended valve guide life
• Black Nitride Coating: Optional black nitride surface treatment provides harder surfaces, smoother finishes, less friction, and longer service life
• CNC Machined to Strict Tolerances: Precision-machined seat geometry and runout tolerances ensure optimal sealing and consistent performance
• Optimized Valve Angles: Application-specific back cut, undercut, and head angles maximize exhaust flow rates for each engine application
• Single Groove Design: Single-groove keeper configuration provides superior valve stem protection against uncontrolled movement and accelerated wear

Supertech Performance brings over 30 years of motorsport engineering experience to every valve they manufacture. Advanced quality control methods including ultrasonic testing, X-ray inspection, laser measurement, and Finite Element Analysis (FEA) ensure consistent, race-proven quality. The HYEVI-5532 exhaust valve is the ideal upgrade for turbocharged Hyundai builds seeking long-term reliability at elevated power levels.
