Blox Racing High Compression Intake Valve Set For D-series SOHC VTEC (D16Z, D16Y) - BXPT-20250 NPT to BSPT The matte-black powder coat finishBlox Racing High Compression Intake Valve Set For D series SOHC VTEC (D16Z Y) BLOX Racing high compression standard size 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. Black nitride provides the valve head with superior protection against wear and corrosion and greatly reduces the
