Supertech Honda K20/K24 Black Nitrided Exhaust Valves

Supertech’s valve design prioritizes durability, offering higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc for maximum longevity. With strict dimensional tolerances and precision-finished seats, Supertech intake valves provide an unmatched sealing and performance solution. The valves also feature a Superfinished stem, reducing surface roughness to one-third of that of chrome-coated valves, resulting in superior performance and durability. This meticulous production process, from forging to Superfinishing, ensures that Supertech valves are free of imperfections and precisely dimensioned for peak performance.
