Bosch 0445120241 Common Rail Fuel Injector 4930485 for Cummins ISLE

1. Product Overview

Brand new Bosch 0445120241 common rail fuel injector for Cummins ISLE engines, Cummins OE number 4930485. The pairing of this Bosch number with 4930485 is evidenced model-by-model in dealer listings; a DS catalogue cross-cluster that includes this Bosch number lists the same OE pool as supporting evidence (the cluster by itself is not a per-model assignment, and the OE is not rested on it alone). The in-family cross number 5263304 also belongs to this injector — listings that hang 5263304 on 0445120070 are bundle errors and have been rejected. No Bosch exchange number could be confirmed for this injector, so none is shown. Family warning: 0445120236 and 0445120237 share this injector’s control valve F00RJ01941 but use different nozzles (0241 = 0433172199, 0236 = 0433172203, 0237 = 0433172201) — they are NOT interchangeable. Always order by the Bosch number engraved on your old injector.

4. Cross-Reference

Note: 5263304 belongs to this injector — do not use it for 0445120070. The number 3976631 appears alongside this Bosch number in one listing title, but no source attributes it to this injector, so it is not listed as an OE or cross number here. No Bosch exchange number could be confirmed.
