Supertech Toyota 2JZ Sodium Filled Inconel Exhaust Valve - +1mm Oversize - Set of 8

This is a set of eight Supertech +1mm oversize exhaust valves for the Toyota 2JZ engine. These valves are constructed from Inconel, a strong nickel-chromium alloy known for its high-temperature strength and resistance to corrosion, making them a solid choice for performance builds where exhaust temperatures can get extreme. The sodium-filled stems help to dissipate heat away from the valve face and into the cylinder head, which can improve valve longevity and performance under demanding conditions. If you're rebuilding the top end of a 2JZ, especially for boosted applications or track use, these valves offer improved durability over stock components.

The Inconel material is crucial for handling the intense heat generated by high-performance 2JZ engines. Combined with the sodium-filled stems, these valves are built to withstand the rigors of sustained high RPMs and significant cylinder pressures. The +1mm oversize dimension means these valves have a slightly larger diameter than stock, which can help improve flow and sealing when used with appropriately sized ports and seats. This set includes all eight exhaust valves needed for a complete engine build.
