👨‍🔧 Tech Notes & Installation Guide

1. 💰 Why Replace the Full Set?

   • The Risk: Mixing a brand-new Electronic Unit Injector (EUI) with old, worn units on a 6-cylinder Euro 5 engine causes severely uneven fuel delivery. This leads to rough idling, heavy drivetrain vibration, decreased payload capacity, and potential DPF/emissions system issues.

   • The Fix: Take advantage of our Volume Discounts to install a matched set of 6 units. This ensures uniform injection pressure across all cylinders and restores the smooth, reliable factory horsepower your Volvo truck is known for.

2. ✅ Direct Replacement (No Coding Required):

   • These aftermarket unit injectors are precision-calibrated on the test bench to deliver optimal flow rates right out of the box. No IMA coding or ECU programming is required—simply install, adjust the mechanical valve lash/tappet clearance to Volvo’s exact specifications, and start the engine. Perfect for quick and hassle-free fleet maintenance.

3. ⚠️ Critical Cleaning Step:

   • High-pressure EUI systems are extremely sensitive to contaminated fuel. The entire fuel delivery system MUST be thoroughly flushed prior to installation. Always install a brand-new, high-efficiency fuel filter to protect the precision plunger inside the new injector from microscopic debris.
