Supertech Mazda Miata 1.6L Black Nitrided Exhaust Valve - Set of 8

Supertech is known for making well-built engine components, and this set of eight black nitrided exhaust valves for the Mazda Miata 1.6L is a great example. If you're rebuilding the top end of your Miata's engine, these valves are designed to handle the heat and stress of everyday driving and performance use. The black nitriding process hardens the surface of the valve, which helps improve wear resistance and durability over time.

These valves are a direct replacement for your stock exhaust valves, meaning they fit right into your existing valve seats. The black nitriding not only adds a layer of protection against wear but also helps the valve seal better within the cylinder head. This can lead to improved compression and overall engine performance. They are built to be a solid option for anyone looking to refresh their Miata's engine internals.
