Supertech Mazda/Ford Duratec 2.0L/2.3L Black Nitrided Exhaust Valve - Set of 8

This set includes eight Supertech black nitrided exhaust valves, specifically made for Mazda and Ford Duratec 2.0L and 2.3L engines. These valves are a direct replacement for your stock exhaust valves, helping to restore proper engine function 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 and pressures. This treatment also helps to improve the valve's sealing capabilities. These valves are well-built and designed to handle the demands of daily driving and more spirited use.

If you're rebuilding the top end of your Duratec engine, this set of eight valves is a solid option to consider. Ensure you have the correct tools and follow manufacturer guidelines for installation to get the best results.
