Supertech Performance BMEVI-1045S-LC Inconel Sodium Filled Exhaust Valve BMW - S54

The Supertech Performance BMEVI-1045S-LC is a premium Inconel sodium-filled exhaust valve engineered specifically for BMW M3 S54B32 engines. This high-performance valve combines advanced materials and innovative cooling technology to deliver exceptional durability in demanding turbocharged and naturally aspirated applications.

Key Features:

• Inconel 751/Nimonic alloy construction for superior high-temperature resistance
• Sodium-filled hollow stem design reduces valve head temperatures significantly
• +1.0mm oversized head diameter (31.5mm) for improved flow characteristics
• 5.95mm stem diameter with single groove keeper design
• 119.6mm overall length for precise fitment
• One-piece forged construction for maximum strength and reliability
• Black nitride coating reduces friction and increases wear resistance
• Approximately 10% lighter than standard valves while offering superior cooling

Supertech sodium-filled valves transfer heat more efficiently from the valve head to the cylinder head, improving material strength and durability while allowing tuners greater flexibility with spark timing advances. The combination of Inconel alloy and sodium filling makes this valve ideal for high-boost turbo applications, high-RPM naturally aspirated builds, and engines running aggressive fuels. Each valve undergoes precision CNC machining, specialized heat treatment, and rigorous quality control including ultrasonic testing to ensure optimal performance and longevity.

Application: BMW M3 E46 (2000-2006), BMW Z3M E36 (2001-2003), BMW Z4M E85/E86 (2006-2008) with S54B32 engine. Sold individually.
