Supertech Black Nitride Exhaust Valves - Set of 4 | Multiple Volkswagen Fitments (VWEVN-1024-4)

Volkswagen 1.8L Black Nitride Exhaust Valves 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.
