2004.5-2007 Dodge Ram 2500 & 3500 5.9L Cummins Common-Rail Fuel Injector (325 hp) | Bosch 0445120238 New
Bosch 0445120238 is a new Bosch common-rail injector, not a rebuild, for the 5.9L Cummins ISB in 2004.5 to 2007 Dodge Ram 2500 and 3500 trucks. That is the 325 hp engine, often called the Cummins 600, from late-production 2004 through 2007. It replaces Cummins 5263316, Mopar 5135790AD and R5135790AF, and the earlier Bosch numbers 0445120032, 0445120103, 0445120114 and 0445120208. Sold as one injector; the engine takes six.
The remanufactured version of this injector carries Bosch number 0986435505. We list that one separately as a Bosch Authorized Remanufactured injector rebuilt by Valley Fuel Injection & Turbo, and both fit the same trucks. The 2003 to early 2004 engine (305 hp) takes a different injector, Bosch 0445120255, so check a 2004 truck before you order. Hard starting, a rough idle, a miss under load or white smoke are the usual complaints. Dirt and water in the fuel are what kill these injectors, so change the filters and plan on new connector tubes when the injectors go in.
Confirm Fitment Before You Order
2004 is a split year. Early-production 2004 trucks with the 305 hp engine take Bosch 0445120255, and late-production 2004 trucks with the 325 hp engine (sold as 2004.5) take this one. They are not the same injector. Send us your VIN, or the engine serial number and CPL from the engine data plate, and we will match it. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
