Supertech Performance MEVI-1012-12 Inconel Exhaust Valve Set +1mm Oversize 6G72

These racing valves feature a +1mm oversize design with precise dimensions of 31.50mm head diameter, 6.54mm stem diameter, and 105.5mm overall length.

Inconel Construction for Extreme Heat:

• Manufactured from Inconel 751 nickel-base superalloy material specifically engineered for high-temperature exhaust applications
• Superior heat resistance makes these valves ideal for turbocharged and supercharged engines that experience extreme exhaust gas temperatures
• One-piece forged construction ensures maximum strength and durability under demanding racing conditions
• Special heat treatment process optimized for the correct hardness levels for performance motor applications

Performance Features:

• Precision-ground seat faces provide repeatable sealing and optimal combustion efficiency
• Hardened valve tips exceed 52 HRC for extended valve train component life
• Controlled stem finish ensures consistent stem-to-guide clearance and reduced friction
• Swirl-polished valve heads deliver stable flow characteristics
• Superfinishing process guarantees perfect surface finish on every valve

Perfect for high-performance builds requiring the ultimate in exhaust valve durability and heat resistance.
