Made from stainless steel with a nitride coating
The Supertech intake valves are engineered to exact tolerances, and are made with nitride coated stainless steel. The nitride coating makes the valves have better lubricity, an increased surface hardness for advanced wear resistance, and increased resistance to higher cylinder temperatures.
