Supertech Nissan RB26 30.15 x 6.94 x 102.70mm - +1mm Oversize- Inconel Exhaust Valve - Set of 12

Crafted from Inconel, a high-nickel alloy known for its exceptional heat resistance, these Supertech exhaust valves are built to handle the demanding conditions found in high-performance Nissan RB26 engines. Each valve measures 30.15mm in diameter with a 6.94mm stem and a 102.70mm overall length, and this set includes 12 valves, precisely what you need for a complete engine rebuild. The Inconel material is crucial for exhaust valves because it can withstand the extreme temperatures generated during combustion, especially in turbocharged or modified engines, helping to prevent valve distortion or failure.

These valves are also +1mm oversize, meaning they are slightly larger in diameter than stock. This is a common upgrade when rebuilding an engine, especially if the valve seats have been reconditioned or if you're looking to improve sealing and flow. The precise dimensions and the robust Inconel construction ensure they will fit right into your RB26 cylinder head, providing a solid foundation for your engine's top end. Supertech is a well-known name in performance engine components, and this set reflects their focus on using appropriate materials for critical engine parts.

When undertaking a rebuild of your RB26's cylinder head, using valves made from a material like Inconel is a smart choice for longevity and performance under stress. This set provides all 12 exhaust valves needed for the engine, ensuring consistency across all cylinders. Always refer to your engine's service manual for specific installation procedures and torque specifications.
