Bosch 0445120255 Common Rail Fuel Injector for Dodge Ram Cummins 5.9 2003-2004.5

1. Product Overview

Brand new Bosch 0445120255 common rail fuel injector for Dodge Ram 2500 / 3500 trucks with the Cummins 5.9L engine, model years 2003–2004.5 (early build only, CPL 8213 / 8228 / 8412, 250/305 hp) — three independent US dealer sources agree on this application. This Bosch number is the successor number in the same application family as 0445120018: the application and the Bosch exchange number 0986435503 are the same, but the nozzle is different (0433175519) — the two pages cross-reference each other, and you should order by the engraved Bosch number. Year boundary: for 2004.5–2007 trucks the correct injector is 0445120238 — it is NOT interchangeable with this one. No single model-specific main OE has been settled for this number: dealer cross-references list a family pool of Cummins and Mopar numbers for this application instead (see Cross-Reference), so no one number from that pool is presented as this injector’s own OE.
