Bosch 0445120121 Common Rail Fuel Injector 4940640 for Cummins ISLe EU3

1. Product Overview

Brand new Bosch 0445120121 common rail fuel injector for the Cummins ISLe engine (EU3), Cummins OE number 4940640 (a Cummins catalogue volume and multiple market listings agree). Headline claims in some listings attaching other engine families to this number are keyword stuffing and are not adopted — the catalogue application is ISLe EU3. Only a China-region Bosch remanufactured number is published for this part (0986AD1047); no international 0986435xxx eXchange number has been confirmed, so that field is noted rather than filled. The same ISLe engine is also served by 0445120122 with a different OE number and different internals — the two pages are linked and the engraved number decides.
