FAQ

Q: Is the 093400-6840 nozzle a direct replacement for my original injector?

A: Yes, this nozzle (DLLA145P684) is a direct OEM replacement for the DENSO 093400-6840. However, it is only the nozzle tip. You will need to install it onto your existing injector body. We recommend professional installation to ensure proper sealing and calibration.

Q: How can I verify that this nozzle will fit my engine?

A: Please check the part number stamped on your old injector nozzle. If it matches 093400-6840 or DLLA145P684, it will be a direct fit. If you are unsure, please provide your engine model (e.g., Isuzu 4HK1, Hino J08C) or your vehicle VIN to our sales team for verification.

Q: What is the recommended maintenance procedure for these nozzles?

A: Diesel fuel injector nozzles are high-precision components. We recommend having them inspected and replaced every 100,000-150,000 kilometers or as part of a major engine overhaul. Always use clean, high-quality diesel fuel and replace fuel filters regularly to extend the life of your injectors.
