Designed for high-performance engine builds, this set of eight Supertech Black Nitrided exhaust valves is engineered for Mazda and Ford Duratec 2.0L and 2.3L engines. These +1mm oversize valves offer increased flow capacity over stock components, making them a critical upgrade for builds targeting higher horsepower through forced induction or high-RPM naturally aspirated tuning.

Supertech utilizes a specialized Black Nitriding process to enhance the valve's surface hardness and reduce friction within the valve guide. This treatment improves wear resistance and fatigue life, allowing the valves to withstand the extreme thermal loads found in racing environments. Please note that +1mm oversize valves require professional machining of the valve seats for proper fitment and sealing.
