This Supertech intake valve is a single black‑nitrided valve for Mazda and Ford Duratec 2.0L and 2.3L applications. Offered as an individual replacement, the nitrided finish improves surface hardness and wear resistance while maintaining original valve form. It suits rebuilds or performance valve train refreshes where direct replacement intake valves are required for Duratec 2.0/2.3 engines.
