This is the Bosch 0432191740, a new mechanical fuel injector (nozzle and holder assembly) made by Bosch, not a rebuild. It is for the Cummins 6CTA 8.3L, the mechanical C Series six cylinder with the in-line Bosch injection pump. It replaces Cummins 3919058 and 3802288, and Case lists the same injector as J919058.

Some sellers file this number under ISC 8.3L. The catalogs that tie it to an engine build put it on the mechanical 6CTA, so order it by the Cummins number on your old injector, not by engine name alone. Electronic ISC 8.3L engines are listed with other injectors, such as Bosch 0432191426 (Cummins 3948529). A miss, white or gray smoke, a fuel knock or hard starting point at worn nozzles. The engine takes six injectors.
