About this part

Product Details

These Supertech exhaust valves are black nitrided, a surface treatment that hardens the valve face and stem. This makes them more resistant to wear and heat, which is crucial for exhaust valves that see high temperatures. This set includes eight +1mm oversize valves, designed specifically for the 1.6L Mazda Miata engine.

When you're rebuilding the top end of your Miata's 1.6L engine, using valves that can handle the heat and stress is important. The black nitride finish helps improve durability and can contribute to a better seal. The +1mm oversize dimension means these valves are slightly larger than stock, which can be beneficial for engines that have been ported or modified to improve airflow, helping to restore or even enhance compression and sealing.

If you're working on a performance build or a thorough engine overhaul for your 1.6L Miata, these valves are a solid option. They are well-made and designed to fit right into the factory valve seats, assuming the seats have been machined to accept the +1mm size. Always refer to your engine's service manual for proper installation procedures and specifications.
