Description
Stainless Steel Intake Valves:
All Supertech stainless steel intake valves begin with a one piece forging, the valve head undergoes 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 receives 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
Supertech Valves are available in either stock replacement standard size, or +1mm oversized valve head diameter. Oversized valves have a larger skirt area, providing increased flow at a lower lift.
