Bosch 0445120239 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120239 common rail fuel injector, supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Bosch parts data records nozzle 0433172200 and control valve F00RJ02130 for this number. A single catalogue fragment points to a Cummins QSB5.9 application, but that is one source only and is not confirmed, and no OE number has been confirmed for this injector — so no application is stated as fact here. Warning: listings that pair this number with Cummins OE 4993482 are bundle errors — 4993482 belongs to 0445120133. This injector shares its nozzle and valve with 0445120256, but the OE and application records differ — the two are NOT interchangeable. Always order by the number engraved on your old injector, and send us a photo of the engraving before ordering so we can verify the match free of charge.

3. Fitment

To be confirmed — a single catalogue fragment suggests Cummins QSB5.9, but this is 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: an OE candidate (5263312) has been suggested by catalogue-fragment elimination only — it is unconfirmed and is NOT stated as this injector’s OE number. Do not use 4993482 for this number; it belongs to 0445120133. No Bosch exchange number could be confirmed for this injector.
