Bosch 0445120516 Common Rail Fuel Injector for Caterpillar C7.1 (Universal Number for 0445120347 / 0445120348)

1. Product Overview

Brand new Bosch 0445120516 common rail fuel injector — the compatible / universal counterpart of Bosch 0445120347 and 0445120348. The manufacturer’s technical files for both main numbers list 0445120516 as their compatible number, so this page follows the main numbers’ settled application: Caterpillar C7.1 engines and Caterpillar OE number 371-3974, which are additionally confirmed by multiple market listings for the main numbers. The three pages are linked. This number’s own nozzle, control valve and exchange number have no per-number source and are left blank — nozzle data documented for the main numbers is not transferred to this universal number. This universal number and the two main numbers are different models: always order by the exact Bosch number engraved on your old injector.

2. Specifications

3. Fitment

Caterpillar C7.1 engines, including 320D2 machines — the settled application of main numbers 0445120347 / 0445120348, for which this number is the documented universal counterpart. 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 number itself, so none is listed. 371-3974 is a Caterpillar OE number — do not confuse it with unrelated Perkins T-prefix part numbers, which have nothing to do with this injector.
