Bosch 0445120144 Common Rail Fuel Injector 4944476 for Cummins ISLe QSL9

1. Product Overview

Brand new Bosch 0445120144 common rail fuel injector (type CRIN1) for Cummins L-series engines — ISLe / QSL9, 8.9L; some sources describe this engine family in 8.3L terms, so please confirm against your engine nameplate before ordering. The confirmed Cummins OE number for this injector is 4944476. A second OE number is disputed between this part and 0445120237 in market and catalogue material, so it is deliberately not printed here — if your old injector carries a different Cummins number, send us a photo of the engraving and we will match it before you order. No Bosch eXchange number is published for this part. Its control valve F00RJ01941 is shared by many numbers in this family — a shared valve does not make them interchangeable.
