This is the Bosch 0986441028, an N3 electronic unit injector remanufactured by Bosch for the Detroit Diesel Series 60. It is the exchange version of Bosch 0414703002, which Detroit sells as R414703002. Catalogs list the N3 injector for DDEC V engines, and Detroit’s own part name and seller catalogs put 0414703002 on the 12.7L. It is sold each, and the engine takes six.

The N3 is the later Series 60 unit injector, a different design from the earlier DDEC III / IV injectors such as Detroit 5235575 or 5237821. There is also a 14.0L N3, Bosch 0414703003 (remanufactured 0986441029), which is a separate part number. A miss under load, a rough idle, white or black smoke, fuel in the oil or a cylinder cutout test that points at one hole are the usual reasons these get replaced. A refundable core applies.
