Supertech Nissan VQ35 Inconel Exhaust Valve - Set of 12

Supertech sodium-filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures, which is required for modern turbo engines. A cooler valve improves material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. This combined with an average weight reduction of 10% makes it a high-performance valve. The Inconel 751 Nickel Base Alloy material is specifically used for exhaust valves in engines that reach very high temperatures, and its use is growing with the application of turbos and superchargers.
