Supertech Toyota 1GRFE Black Nitrided Exhaust Valve- +1mm Oversize - Set of 12

This set includes 12 Supertech black nitrided exhaust valves, each measuring 1mm oversize. These valves are specifically made for the Toyota 1GRFE engine, a common V6 found in many Toyota and Lexus trucks and SUVs. If you're rebuilding or upgrading the top end of your 1GRFE, these valves are a key component for ensuring proper sealing and performance.

The black nitriding process hardens the surface of the valve, making it more resistant to wear and heat. This is especially important for exhaust valves, which operate under high temperatures. The +1mm oversize dimension means these valves are slightly larger than stock, which can be beneficial for engines that have had their valve seats re-machined or for those looking to maximize flow potential after a porting job. They are well-built to handle the demands of the exhaust side of the engine.
