Description

Supertech exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. They feature a black nitride treatment for superior hardness while maintaining core ductility. The valve stem has a “Superfinish” with a surface roughness of about 1/3 of a regular valve. These features result in less friction, better flow rates, better sealing, improved durability, and reduced carbon buildup.
