Supertech Toyota 4AGE 16V Black Nitrided Exhaust Valve - Set of 8

If you're rebuilding the top end of your Toyota 4AGE 16V engine, you'll want to make sure your exhaust valves can handle the heat and pressure. These Supertech valves are specifically made for that engine, designed to be a direct replacement for your stock ones. They're built to keep your engine breathing efficiently, especially if you're pushing the limits or just want reliable performance.

What sets these apart is the black nitriding treatment. This process hardens the surface of the valve, making it more resistant to wear and corrosion. It also helps improve the sealing surface over time. Each valve in this set of eight is well-built and ready to be installed in your 4AGE cylinder head. They are designed to fit right into the stock valve guides and seats, simplifying the installation process for your engine build.
