Bosch 0445120332 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120332 common rail fuel injector (type CRIN3-18, 1800 bar), supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Bosch parts data records nozzle 0433172326 and two control-valve versions (F00RJ02004 / F00RJ01714) for this number. A single technical-file source attributes it to Cummins and gives the candidate OE number 5262128 — but that OE reading comes from a partially legible code with no second source to confirm it, so it is shown as a candidate only, not as this injector’s confirmed OE. No Bosch exchange number has been confirmed. Neighbouring numbers in the same Cummins range are easy to mix up: 5267035 belongs to 0445120329 and 5273750 to 0445120328 — check every digit. This number’s neighbour 0445120333 is a Yuchai injector of a completely different application; the two must never be merged.

3. Fitment

To be confirmed — a single technical-file source indicates Cummins (no specific engine model given), but the application and the candidate OE number are not confirmed by a second source; contact us with the engraved number or VIN. 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 could be confirmed for this injector. The candidate OE number above rests on one partially legible source only — if the OE engraved on your old injector differs, trust the engraving and tell us what it reads.
