Product Overview
Set of 6 high performance single groove 39mm standard intake valves manufactured by SuperTech
Supertech primarily uses enhanced versions for EV8 (21-4n). Valves are fully CNC machined, with a hard chrome treatment, and hard tips. Stainless steel valves are widely used in dragsters and funny cars due to their high-temperature properties.
The CNC process eliminates any imperfections from the forging. They undergo a heat-treatment to ensure proper molecular integrity and uniform grain structure throughout the valve. The hard chrome plating reduces wear and provides optimum anti-friction performance. Excellent for high-performance or racing applications. stronger and lighter than stock valves, better heat resistance. The valve stem design near the head allows for more air flow. Improved rpm and hp.
