MIA's Description

Supertech black nitride intake and exhaust valves for 6G72 3000GT and Stealth. These valves are available in various sizes to match your head diameter. Sold as a set of 12 or individually as needed. Black nitride valves are made from one piece forged stainless steel then go through a special hardening process to lessen the friction between the valve and guide. The microhardness is 800HV minimum, and the surface finish is smoother than chromed stems, reducing friction and power loss at higher engine speeds.
