Bosch 0445120257 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120257 common rail fuel injector, supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Bosch parts data records nozzle 0433172213 and control valve F00RJ02506 for this number; no OE number, application or Bosch exchange number has been confirmed for it, so none is stated as fact here. System warning: this is a CRIN3-18 injector (1800 bar) — a different system generation from most 044512 injectors (CRIN1 / CRIN2, 1600 bar) — so confirm your system’s generation before anything else. The control valve F00RJ02506 is also listed for 0445120199 and 0445120305; a shared valve does not make those injectors interchangeable with this one. 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.
