Bosch 0445120304 Common Rail Fuel Injector 5272937 for Cummins ISC ISL 8.9

1. Product Overview

Brand new Bosch 0445120304 common rail fuel injector for Cummins ISC / ISL 8.9L engines (ISLe / ISL9, QSL8.9 direction; Dongfeng Cummins DCEC applications), Cummins OE number 5272937. The pairing is confirmed by two technical files, a parts catalogue and dealer listings. No Bosch exchange number could be confirmed for this injector, so none is shown. Warning: some marketplace titles bundle the number 5283275 with this injector — 5283275 belongs to 0445120134 (Foton Cummins ISF3.8) and is NOT a cross number for this injector. This injector shares its control valve F00RJ02806 with 0445120292, but the OE numbers and applications are completely different (0292 is a Yuchai injector) — the two are not interchangeable.
