Bosch 0445120212 Common Rail Fuel Injector 5263307 for Cummins ISBe ISB 3.9 4.5 5.9 6.7

1. Product Overview

Brand new Bosch 0445120212 common rail fuel injector (type CRIN1-14/16, 1600 bar) for Cummins ISBe / ISB engines, Cummins OE number 5263307. This OE number belongs to this Bosch number only — one major catalogue mis-files 5263307 under 0445120112; that filing is wrong and has been rejected after cross-checking against dealer cross-reference tables. The remanufactured exchange number is disputed between two sources (0986435571 vs 0986435508) and is therefore not stated as settled — check the engraving on your old injector. Family note: 0445120007 and 0445120273 belong to the same CRIN1-14/16 Cummins ISBe family and share some OE / remanufactured numbers; 0445120211 shares this injector’s control valve but uses a different nozzle and is NOT interchangeable. Always order by the Bosch number engraved on your old injector.
