Bosch 0445120103 Common Rail Fuel Injector 4937700 for Dodge Ram 2500 3500 Cummins 5.9L 2004.5-2007

1. Product Overview

Brand new Bosch 0445120103 common rail fuel injector for the Dodge Ram 2500/3500 with the Cummins 5.9L engine, model years 2004.5–2007. Cummins OE number 4937700. The Bosch eXchange number 0986435505 is the family number for the whole 2004.5–2007 group (0445120032 / 0103 / 0114 / 0208 / 0238): aftermarket remanufactured kits converge the group onto one kit, but the brand-new injectors are not interchangeable with each other. Twin warning: 0445120114 is this injector’s twin — both share nozzle 0433175470, but the control valves differ (this one F00RJ00339, the 0114 F00RJ01945) and the Cummins OE numbers differ (4937700 vs 4940051); the two pages are linked and the engraved number decides. This is not the 2003–2004 injector family (0445120018 / 0445120113, eXchange 0986435503).
