Remanufactured DENSO DCRI107850 (095000-5870 / 095000-7850 / 095000-8830, legacy 095000-5030) common-rail diesel injector for the Mazda 2.0 DI engine (OE RF5C13H50 / RF5C13H50A/B/C, RFY013H50 / RFY013H50A/B). Fits Mazda 6 (GG saloon / GY estate) 2.0 DI 2002–2007 (RF5C / RF7J, 121–136 hp) and Mazda MPV II (LW) 2.0 DI 2002–2006. Note: the 143 hp high-output RF7J (Mazda 5, Mazda 6 GH 2.0 MZR-CD) uses the different DCRI107860 / RF8G-13-H50 injector — not this unit. Fully tested and calibrated to OEM specification with 12 months warranty.

Hard cold starting; rough idle; black smoke under acceleration; misfire on individual cylinders; fuel dilution of engine oil on failed regenerations. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector leak-back beyond specification; nozzle wear causing over-fuelling and oil dilution; seat washer combustion leaks. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Check the oil level for diesel dilution — a documented consequence of worn injectors on this engine. Compare leak-off volumes across all four injectors before ordering. Denso compensation codes must be registered via the manufacturer diagnostic procedure after fitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured DCRI107850 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The DCRI107850 trusted family covers 2 verified vehicle fitments across 1 makes: Mazda. Every fitment listed is registry-verified.
