Supertech Black Nitrided Dish Exhaust Valve - Single | Multiple Fitments (MAEVN-2301D)

Mazda MZR / Ford Duratec Black Nitride Exhaust Valve by Supertech

Supertech exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Some applications call for us to harden certain areas such as the tips and or the seats. For these applications we will often times weld other hard metal alloys to the valve for increased durability.
