Supertech VW R32 VR6 24V Black Nitrided Intake Valve - Set of 6

R32 24V VR6 engines include four sets of six valves, each engine has one set of long intake, one set of short intake, one set of long exhaust, and one set of short exhaust. This is for one set of six SHORT Supertech Intake valves for R32 24V VR6 engines. All Supertech stainless steel valves begin with a one piece forging, the valve head undergos a two step forging process for excellent material grain flow. Each valve is then CNC machined to ensure exact final dimensions. Next, another heat treatment and nitride hardening treatment for final stress relieving to ensure valve strength. The valve recieves one final grinding, followed by Supertech's patented Superfinishing of the entire surface. This ensures each valve is free of any imperfections and the dimensions are precise.
