👨‍🔧 Tech Notes & Installation Guide

1. 💰 Why Replace the Full Set?

   • The Risk: Mixing new injectors with worn mechanical injectors causes uneven fuel spray patterns and Cylinder Power Imbalance (Engine Vibration, Knocking & Heavy Smoke).

   • The Fix: Use our Volume Discount to install a matched set of 4 units to restore factory injection pressure and atomization.

2. ✅ Mechanical Calibration (No Coding):

   • This is a traditional mechanical nozzle assembly. It is pre-calibrated to the OEM specified pop-off pressure (245 bar). No electronic IMA coding is required.

3. ⚠️ 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.
