Bosch 0445120221 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120221 common rail fuel injector, supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). No reliable catalogue source could be confirmed for this number: no OE number, no nozzle, no control valve and no exchange number are on record, and the only market leads conflict with each other — bundled listings variously attach it to MAN engines and to Weichai WP10, and bundled titles are not evidence of fitment, so neither claim is stated here. In particular, MAN OE 51.10100-6126 belongs to 0445120217 and the Weichai number 612600080611 is itself disputed between 0445120213 / 0445120214 — neither may be used for this injector. 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 — the only market leads (MAN vs Weichai WP10 bundled listings) conflict and are not accepted as evidence; 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 OE number, nozzle, valve or exchange number is stated for this injector — none could be confirmed from reliable sources. Do not borrow numbers from 0445120217 (51.10100-6126) or from the Weichai 0445120213 / 0445120214 family.
