Supertech Performance NIVN-1042 Performance Valve for Nissan RB20DE/RB20DET Skyline

Supertech Performance NIVN-1042 is a high-performance engine valve designed specifically for Nissan RB20DE and RB20DET engines found in Skyline models. Engineered with over 20 years of manufacturing expertise, this valve delivers enhanced flow rates, superior durability, and exceptional quality for demanding performance applications.

Key Features:

• One-piece forged stainless steel construction for maximum strength and reliability
• EV8 (21-4N) stainless alloy material with application-specific heat treatment
• Available with chrome coating or black nitride surface treatment for reduced friction
• Engineered for optimal flow characteristics and high-temperature performance
• Precision-manufactured to OEM specifications with performance enhancements
• Suitable for naturally aspirated and forced induction applications

Supertech offers advanced coating options to address high-heat environments: chrome coating for proven performance durability, or black nitride hardening treatment that provides a smoother surface finish and reduced stem-to-guide friction compared to chrome. Each valve is manufactured to exacting tolerances to ensure proper fitment and longevity in high-performance RB-series engine builds.

Important: Valves are sold individually. Calculate total quantity needed based on your engine configuration (typically 16 valves for a complete RB20 engine).
