FAQ

1. Is this nozzle a direct replacement for my Nissan’s injector?

Yes, this is an OE specification replacement part. However, we strongly recommend checking the existing part number on your injector. It must match DN0PDN121, 093400-8220, or 0 434 250 121 to guarantee a perfect fit. If you are unsure, please contact us with your engine model and injector code for verification.

2. What is the typical installation procedure?

Installation should be performed by a qualified diesel technician. The process involves removing the old injector, cleaning the injector bore, and installing the new nozzle. It is critical to replace copper washers and seals and to tighten the injector to the manufacturer’s specified torque to prevent leaks and ensure proper operation.

3. How should I store these nozzles before installation?

To maintain the nozzle’s precision, store it in its original packaging in a clean, dry environment. Avoid exposing the nozzle tip to dirt or moisture. For long-term storage, keep the part in a climate-controlled area away from extreme temperatures and corrosive substances.
