Supertech's Black Nitride exhaust valves are manufactured from premium EV8 (21-4N) stainless steel and finished with a proprietary Black Nitride surface treatment. This coating provides superior hardness, reduced friction, and enhanced corrosion resistance compared to standard stainless valves.
Each valve is precision-machined to OEM tolerances and undergoes rigorous quality control including dimensional inspection, hardness testing, and surface finish verification. The result is a valve that delivers consistent, reliable performance in both street and competition applications.
Ideal for naturally aspirated, turbocharged, and supercharged engines where exhaust valve durability is critical. The Black Nitride coating excels in high-EGT environments and is particularly well-suited for engines running lean air-fuel ratios or aggressive ignition timing.
