Bosch 0445120320 Common Rail Fuel Injector for MAN

1. Product Overview

Brand new Bosch 0445120320 common rail fuel injector (type CRIN3-18, 1800 bar) for MAN heavy commercial vehicles. Bosch parts data records nozzle 0433172309 and control valve F00RJ02410 for this number. This injector forms a matched pair with 0445120341: the technical documentation lists the two Bosch numbers together against the same pair of MAN OE numbers (51.10100-6169 and 51.10100-6181) and the same pair of Bosch exchange numbers, and no source supports splitting those pairs between the two numbers — so both OE numbers and both exchange numbers are shown on both pages. The pair are not blindly interchangeable: 0445120341 uses a different nozzle (0433172343), so always order by the number engraved on your old injector. See also the linked pages for 0445120341 and 0445120353 (same MAN family).

2. Specifications

3. Fitment

MAN heavy commercial vehicles (engine application to be confirmed against your old injector’s engraving — this number and 0445120341 share the same OE pair, and 0445120353 in the same family carries its own D2066 application table). 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: the two MAN OE numbers and the two exchange numbers above are documented at pair level for 0445120320 + 0445120341 together; no source assigns one OE to one Bosch number only, so both are listed on both pages. Nearby MAN numbers such as 51.10100-6115 or 51.10100-6202 belong to other injectors — do not use them for this one.
