Bosch 0445120250 Common Rail Fuel Injector for Cummins

1. Product Overview

Brand new Bosch 0445120250 common rail fuel injector (type CRIN1-14/16, 1600 bar) for Cummins engines. The OE number 5263321 and the exchange number 0986435533 both rest on a single technical-file source and are marked to be confirmed (Cummins’ own store does sell a remanufactured injector under the number 5263321, which confirms the number exists, but its pairing with this Bosch number is single-source). The same technical file lists 0445120060 as a compatible part number — a related Cummins injector, NOT the same model. Family warning: the numbers 0250–0256 sit in one Cummins OE segment with near-identical OE numbers (0250 = 5263321, 0251 = 5263314, 0252 = 5263315, 0256 = 5263319) — one digit apart and easily cross-posted, so always order by the engraved Bosch number.
