FAQ

Q1: Is this nozzle a direct replacement for my original DENSO injector (105015-6981)?
Yes. This nozzle (DLLA160SN698) is the exact OE specification replacement for part number 105015-6981. It matches the original spray angle (160°), dimensions, and flow characteristics. We recommend checking the nozzle tip length and diameter against your injector body to confirm compatibility.

Q2: What maintenance is required after installing a new injector nozzle?
After installation, we recommend bleeding the fuel system to remove air, and checking the injector back-pressure. For optimal performance, it is best practice to replace the copper washer and torque the injector to the manufacturer’s specification. A visual inspection of the fuel filter is also advised to prevent future contamination.

Q3: Can I install this nozzle myself, or do I need specialized tools?
While a skilled mechanic can replace the nozzle, we recommend using a calibrated torque wrench and a nozzle seat reamer. Due to the high precision involved, improper installation can lead to poor atomization or engine damage. For best results, have the installation performed by a qualified diesel technician.
