Bosch 0445120366 Common Rail Fuel Injector for Cummins ISF2.8 / ISF3.8

1. Product Overview

Brand new Bosch 0445120366 common rail fuel injector with Cummins OE number 5271684, for Foton Cummins ISF2.8 / ISF3.8 engines. The OE pairing and application are supported by several independent supplier listings that agree with each other. One listing’s QSB 6.7 attribution for this number rests on that single source, conflicts with the consistent ISF evidence, and is not adopted. Important distinction: the ISF3.8 also uses another Bosch number on this site, 0445120297 (Cummins OE 5264272) — 0445120366 and 0445120297 are different calibrations and are NOT interchangeable, so order strictly by the Bosch number engraved on your old injector. No Bosch exchange number has been confirmed, and nozzle / control valve values could not be retrieved in this round, so those fields are left blank.

3. Fitment

Foton Cummins ISF2.8 and ISF3.8 engines. Fitment data is for reference only — please confirm by the number engraved on your old injector or send us your VIN before ordering.

4. Cross-Reference

Note: no Bosch exchange number, nozzle or control valve could be confirmed for this injector, so none is listed. Two different Bosch numbers serve the ISF family — the engraved Bosch number and OE number on your old unit decide which one you need.
