💰 Why Replace the Full Set?

• The Risk: Mixing a brand-new mechanical injector with old, worn units causes severely uneven fuel delivery. This leads to Cylinder Power Imbalance, resulting in engine vibration, decreased fuel efficiency, and heavy exhaust smoke.

• The Fix: Take advantage of our Volume Discount to install a matched set of 6 units to restore smooth, factory-level combustion and power.

✅ Mechanical Calibration (No Coding):

• This is a traditional mechanical nozzle assembly. It is pre-calibrated on the test bench to the OEM specified opening pressure (245–259 bar). No electronic IMA coding is required for installation.

⚠️ Critical Cleaning Step:

• The entire fuel delivery system MUST be thoroughly flushed to remove metal shavings and contamination before installation. Always install a brand-new fuel filter to protect the nozzle needle from scoring.

💰 Why Replace the Full Set?

• The Risk: Mixing a brand-new mechanical injector with old, worn injectors causes severely uneven fuel spray patterns, leading to Cylinder Power Imbalance (Engine Knocking, Vibration & Heavy Smoke).

• The Fix: Use our Volume Discount to install a matched set of 6 or 8 units to restore smooth factory performance.

✅ Mechanical Calibration (No Coding):

• This is a traditional mechanical nozzle assembly. It is pre-calibrated on the test bench to the OEM specified pop-off pressure (290-302 bar). No electronic IMA coding is required.

⚠️ Critical Cleaning Step:

• The entire fuel delivery system MUST be flushed to remove contamination. Install a brand-new fuel filter to protect the nozzle needle from scoring and sticking.
