Bosch 0445120445 Common Rail Fuel Injector for Sinotruk HOWO T7H / A7 (Universal Number for 0445120321)

1. Product Overview

Brand new Bosch 0445120445 common rail fuel injector — the compatible / universal counterpart of Bosch 0445120321. The manufacturer’s technical file for 0445120321 lists this number as its compatible number, so this page follows the main number’s settled application: Sinotruk OE 200V10100-6126 and the HOWO T7H / A7 fitment below, which rest on two independent sources for the main number. The two pages are linked. This number’s own nozzle, control valve and exchange number have no per-number source: the nozzle and control valve documented for 0445120321 itself belong to that number and are deliberately NOT transferred to this page. Neighbour warning: the 0445120444 / 0445120415 pair uses OE 200V10100-6127 — one digit apart from this page’s 200V10100-6126, for a different calibration of the same Sinotruk MC platform. Order by the engraving on your old injector, never by the near-identical neighbour number.

3. Fitment

Sinotruk HOWO T7H / A7 and Sitrak trucks with MC11 / MC13 engines — the settled application of main number 0445120321, 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. NOT this number’s OE — 200V10100-6127 belongs to the 0445120444 / 0445120415 pair; it differs by one final digit. A claim found elsewhere labelling the main number 0445120321 a Cummins ISLe injector was checked against the Sinotruk evidence and rejected — this family is Sinotruk MC only.
