Bosch 0445120336 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120336 common rail fuel injector (type CRIN3-18, 1800 bar), supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Bosch parts data records nozzle 0433172144 and two control-valve versions (F00RJ02004 / F00RJ01714) for this number. A single technical-file source gives a detailed Cummins QSB6.7 (6.7L) vehicle match for it and the candidate OE number 5289380 — but that OE reading is reconstructed from a partially legible code and has no second source, so it is shown as a single-source candidate only, pending confirmation. A different catalogue attribution for this number was checked and rejected as a known column drift in that catalogue; it is not reproduced here. No Bosch exchange number has been confirmed. This injector shares its valve pair with 0445120332 but uses a different nozzle (0433172144 vs 0433172326) — the two are not interchangeable.

3. Fitment

To be confirmed — a single technical-file source gives a Cummins QSB6.7 (6.7L) match, but this rests on one source only; contact us with the engraved number or VIN and we will verify before you order. 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.
