BLOX Racing D-series SOHC VTEC (D16Z6/D16Y8) exhaust valves are forged from EV8 stainless steel. Each valve then undergoes a heat treatment process to increase strength then coated using black nitride to provide superior wear resistance and minimize power-robbing friction. BLOX Racing valves are specially designed to increase intake and exhaust airflow through the cylinder head.

BLOX Racing valves are flat -- which increases compression by approximately 0.3 points.

For maximum results, use with BLOX Racing valve springs and Ti retainers.

Set includes 8 exhaust valves.
