Browse MTU injector and nozzle references for 2000, 4000, 396, 595, and 956 series engines. New, OEM-alternative, and remanufactured routes are quoted only after the stamped injector number, complete engine model, and serial number have been checked.
MTU common-rail and unit-pump injection systems operate at extreme pressure. Injector performance directly affects combustion balance, exhaust temperature, fuel consumption, and emissions. A single underperforming injector can cause hard starting, rough running, excessive smoke, increased return flow, or a cylinder-temperature deviation.
This page is limited to injectors, nozzle holders, nozzle elements, and directly related injection components. We supply new OEM, OEM-alternative, and professionally remanufactured routes when available. A remanufactured option should be supported by a traceable test process and clearly identified as remanufactured in the quotation.
High-demand references include EX52407500064 for MTU 4000 series and X53507500012 for MTU 2000 series. Always send the complete number stamped on the injector body, a clear photo of the connector and nozzle end, and the full engine serial number. Multiple injector variants can exist within one engine series because of power rating, emissions certification, or production revision.
If the fault relates to supply pressure rather than injection quality, use the dedicated MTU fuel-pump catalog. Pump quotations require the pump label, drive arrangement, installation position, engine model, and serial number.
Component Coverage
Use these focused topics to narrow the catalog before sending a part-number list. Final fitment is confirmed against the complete engine or component reference.
MTU Engine Injectors
New, OEM-alternative, and reman injector routes verified by stamped reference and engine serial number.
MTU Fuel Pumps
High-pressure and low-pressure fuel pumps checked against model, rating, and installation position.
MTU Injector Identification
Use the complete body marking, connector, nozzle reference, engine model, and serial number to separate nearby injector variants.

Common RFQ Scenarios
- Bulk replenishment for repeated service items
- Cross-series part-number verification
- Old-stock replacement and supersession checks
- Mixed RFQ lists from service companies or shipyards
For mixed lists, send the spreadsheet as-is. We return line-by-line availability, replacement notes, and practical shipping options instead of a generic catalog reply.
