This is the Bosch 0432133888, a new nozzle and holder assembly, not a rebuild, for the first-generation Dodge 5.9L Cummins 12-valve without the factory intercooler. Catalogs list it for 1988 to 1991 trucks. Some print 1988 to 1993, but the intercooled engine took over partway through 1991. It is the 9 mm tip injector with the Bosch KDAL59P2 holder, and it crosses to Cummins 3909522 and 3905454, Cummins exchange number 3802038RX and Mopar R4429238. Opening pressure is 245 to 259 bar. It is sold outright, with no core to return.

Check the tip size before you order. Where the head takes 7 mm injectors, catalogs list Bosch 0432133874 instead, and the intercooled engine is listed with another 7 mm injector, Bosch 0432133877. A 7 mm injector does not seat in a 9 mm head without a chamber adapter, so match what the head takes. The 1994 to 1998 trucks with the inline pump take 0432133859, 0432133860 or 0432133844. Worn nozzles on these engines show up as black smoke, hard starting, a rough idle or fuel knock. Replace all six together.
