FAQ

Q1: What is the difference between the DN0PDN121 and the 105007-1210?
These are cross-reference numbers for the same physical nozzle. The DN0PDN121 is the manufacturer’s internal part number, while 105007-1210 is the OEM number from the original equipment supplier. They are identical in dimensions and performance.

Q2: How do I know if this nozzle will fit my engine?
First, verify the part number stamped on your old nozzle. If it matches DN0PDN121, 105007-1210, or 093400-8220, it is a direct fit. If you do not have the old part number, measure the thread size (typically M12x1.25 or M14x1.5) and the overall length. We recommend consulting your engine’s service manual for the correct injector specifications.

Q3: What maintenance is required for this injector nozzle?
This nozzle is a wear item. It does not require maintenance itself, but the fuel system should be kept clean. Use high-quality fuel filters and replace them according to your engine’s schedule. If you experience hard starting, rough idling, or black smoke, the nozzle may be clogged or worn and should be replaced. Always replace nozzle sets (e.g., all 4 or 6 injectors) at the same time for balanced engine performance.
