This is a INTAKE KIT of 8 intake valves of your specification.

Supertech's stainless valves are made of SAE EV8 stainless steel, a grade of austenitic stainless with high chromium and manganese content that has been developed specifically for high-temperature valve use. The slight necking-down of the valve stem means there's less blockage of incoming airflow, and the black nitrided finish provides a hard, smooth exterior while the underlying steel structure retains ductility.
