FAQ

Q1: What is the difference between the DN4PD681 and 093400-6810 numbers?

The DN4PD681 is the manufacturer’s part number, while 093400-6810 is the original equipment manufacturer (OEM) number. They are cross-referenced and refer to the same injector nozzle. You can use either number to verify compatibility.

Q2: How do I ensure this nozzle fits my engine?

Please check the existing part number on your old nozzle. If it matches DN4PD681, 093400-6810, 093400-5571, or DN4PD57, this part is a direct replacement. We recommend professional installation to ensure proper seating and torque.

Q3: What are the signs that my injector nozzle needs replacement?

Common symptoms include rough idling, poor fuel economy, black smoke from the exhaust, engine misfire, or difficulty starting. If you experience these issues, inspecting and replacing the nozzle with a high-quality part like the DN4PD681 can restore engine performance.
