Bosch 0445120123 Common Rail Fuel Injector 4937065 for Dongfeng Cummins ISDe

1. Product Overview

Brand new Bosch 0445120123 common rail fuel injector for Dongfeng Cummins engines, Cummins OE number 4937065 (a Cummins catalogue volume, a dealer cross-reference table and multiple market listings agree). On the engine designation the sources are not fully aligned: the catalogue volume and most listings say ISDe, while one dealer table lists this number under ISLe — the ISDe reading is used as the main designation here, and buyers should check the engine nameplate before ordering, as noted in the Fitment section. No Bosch eXchange number is reliably published for this part number.
