FAQ

Q: How do I confirm this nozzle is compatible with my engine?
A: The most reliable method is to match the part number stamped on your original injector nozzle. Cross-reference it with the numbers listed in the “OEM Cross-Reference” section above. Providing your engine model, injection pump model, and equipment serial number to our team can also help verify fitment.

Q: What is the benefit of the S-Type design in this nozzle?
A: The S-Type (or “S” designation) refers to a specific internal geometry and spray hole configuration. It is engineered to provide an optimized fuel spray pattern for specific combustion chamber designs, leading to more efficient burning, better power output, and lower particulate emissions compared to non-matched nozzles.

Q: Are these nozzles sold individually or as sets, and what is your typical lead time?
