Supertech Toyota Supra 1JZGE/1JZGTE Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

Made from Inconel, a high-nickel alloy, these Supertech exhaust valves are built to handle the extreme temperatures found in performance 1JZGE and 1JZGTE engines. The material choice is key here; Inconel is known for its excellent resistance to heat and corrosion, which is crucial for exhaust valve longevity under demanding conditions. This particular valve is a +1mm oversize option, meaning it's slightly larger than the stock valve. This can help improve airflow into the cylinder, especially if you're rebuilding or modifying your engine's top end and looking for a bit more performance.

When you're working on a 1JZ engine, especially a performance build, the details matter. Using valves made from a material like Inconel ensures they can withstand the heat cycles without deforming or degrading. The +1mm sizing is a common upgrade when porting cylinder heads or installing larger camshafts, as it allows the valve to seal better in a slightly enlarged valve seat. This helps maintain compression and ensures efficient combustion.

This is a single valve, so be sure to order the correct quantity for your engine build. It's a solid option for anyone looking to replace worn valves or upgrade their 1JZ's valvetrain with a component that's built for high heat and performance.
