👨🔧 Tech Notes & Installation Guide
-
💰 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.
