FAQ

Q: How do I confirm this is the correct oil nozzle for my specific Isuzu engine?
A: The most reliable method is to cross-reference the part number stamped on your original nozzle. Match it with the numbers listed in the OEM Cross-Reference section above (e.g., 8-94469709-3 or 8-98023-526-0). The engine model (4JB1) must also match.

Q: Is this a single nozzle or a set? Does it require professional installation?
A> This listing is for a single oil nozzle. For optimal engine performance, it is recommended to replace all nozzles in the engine simultaneously. Installation and calibration of fuel injection nozzles require specialized tools and knowledge. We strongly advise installation by a qualified diesel technician to ensure proper torque, seating, and injection timing.

Q: What documentation is provided with international shipments?
A> For all B2B export orders, we provide a complete set of documents including a Proforma/Commercial Invoice, Packing List, and Bill of Lading/Air Waybill. A Certificate of Origin can be provided upon request to facilitate customs clearance in your country.
