Supertech Nissan RB26 30.15X6.94X101.60mm Inconel Exhaust Valve - Set of 12

Crafted from Inconel, a high-nickel, high-chromium superalloy, these Supertech exhaust valves are built to withstand the extreme temperatures found in high-performance Nissan RB26 engines. The material choice is critical here; Inconel offers superior resistance to heat and corrosion compared to standard stainless steel, making it ideal for applications where the exhaust gas temperatures can reach punishing levels. Each valve measures 30.15mm in diameter with a 6.94mm stem and a 101.60mm overall length, precisely matching OEM specifications for a direct fit within the RB26 cylinder head.

This set includes 12 valves, enough to replace all exhaust valves in your RB26 engine. The Inconel construction not only handles heat better but also provides a solid foundation for consistent sealing under pressure and high RPM operation. When you're pushing an RB26 to its limits, whether for track use, serious street performance, or a full-blown build, components like these valves are essential for reliability and longevity. They are designed to maintain their shape and integrity even when subjected to prolonged high heat cycles, which can cause lesser materials to warp or fail.

For builders and tuners working on a performance-oriented RB26, these Supertech Inconel valves are a smart investment in the engine's durability. While they are a direct replacement for the stock valves, it's always recommended to consult the manufacturer's installation guide or a trusted mechanic to ensure proper seating and valve spring compatibility for your specific build. This attention to detail ensures that these high-performance valves will perform as expected and contribute to the overall health of your engine.
