This high quality nozzle is manufactured in Italy and fits all 1994-2003 7.3L Powerstroke Diesels and DT444 engines. Combine these nozzles with our deluxe rebuild kit and rebuild tool for a seamless repair.

Larger nozzles do not increase the fuel capacity of the injector. Larger nozzles are to be installed in modified injectors to reach the desired HP goals.
