FAQ

Q1: How do I confirm this nozzle is compatible with my ISUZU 4JA1 engine?
A1: The surest method is to cross-reference the part number. Remove your old injector nozzle and check for the stamped part number. This DLLA154PN270 nozzle directly replaces parts numbered DLLA154PN270 or 105017-2700. You can also consult your engine’s service manual for the correct injector specification.

Q2: What does “PN270” in the part number signify?
A2: The “PN270” is a flow code that indicates the nozzle’s specific flow rate and spray pattern. It is a critical specification. Using a nozzle with an incorrect PN code (e.g., PN260 or PN280) can lead to poor engine performance, excessive smoke, or potential damage. Always replace with an identical PN code.

Q3: Are these nozzles sold individually or as a set? What is the installation advice?
A3: This part is sold as a single item, with a Minimum Order Quantity (MOQ) of 4 pieces. For optimal engine balance and performance, it is highly recommended to replace all injector nozzles on an engine simultaneously. Installation should be performed by a qualified technician using proper tools, followed by necessary calibration to ensure correct injection timing and pressure.
