Bosch 0445120341 Common Rail Fuel Injector for MAN

1. Product Overview

Brand new Bosch 0445120341 common rail fuel injector (type CRIN3-18, 1800 bar) for MAN heavy commercial vehicles. Bosch parts data records nozzle 0433172343 and control valve F00RJ02410 for this number. This injector forms a matched pair with 0445120320: the technical files for both numbers list the same pair of MAN OE numbers (51.10100-6169 and 51.10100-6181) and the same pair of Bosch exchange numbers (0986435592 / 0986435593), and no source supports assigning one OE to one Bosch number only — so both OE numbers and both exchange numbers are shown on both pages. The pair are not blindly interchangeable: this number’s nozzle (0433172343) differs from 0445120320’s (0433172309) while the control valve is the same, which means the calibrations differ — always order by the number engraved on your old injector. See also the linked pages for 0445120320 and 0445120353 (same MAN family; 0353 carries the D2066 application table). The neighbouring number 0445120340 has an unrelated, unconfirmed application — do not confuse the two.

3. Fitment

MAN heavy commercial vehicles (engine application to be confirmed against your old injector’s engraving — this number and 0445120320 share the same OE pair). 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. The same OE pair and exchange pair are also used by 0445120353 (MAN D2066) — three different Bosch numbers share this documentation set, so the engraved Bosch number on your old injector is the deciding factor.
