Bosch 0445120210 Common Rail Fuel Injector 5254686 for Dodge Ram 2500 3500 5.9 Cummins 2003-2004

1. Product Overview

Brand new Bosch 0445120210 common rail fuel injector for Dodge Ram 2500/3500 trucks with the 5.9L ISB Cummins engine, 2003 to early 2004, 250/305 hp (engine CPL 8213 / 8228 / 8412), Cummins OE number 5254686. It belongs to the 2003–2004 group with 0445120018 / 0113 / 0255, which shares the eXchange number 0986435503 and a set of group Cummins and Mopar numbers. ⚠ Two warnings: (1) Year/power split — trucks from 2004.5 onward (325 hp) use the other group (0445120032 / 0103 / 0114 / 0208 / 0238); the two groups are mutually exclusive. (2) Serial-number trap — 5263307 is NOT this injector’s OE number; it belongs to the neighbouring 0445120212, and the two part numbers are frequently mixed up in catalogues and listings. The nozzle and control valve for this part number could not be verified from Bosch parts data, so those fields are left blank rather than guessed.
