Here is how I replaced the coil packs and spark plug wires in a Hyundai trajet 2000.
Step 1: Removing the Oem Coil Packs and Wires.
There are two 10mm bolts per coil pack. The spark plug wires came off very easily. One coil pack actually disintegrated!
Step 2: Installing the New Coil Packs and Spark Plug Wires.
It took me 5 minutes to install the new parts taking care not to excessively press in the spark plug wires.
Step 3: Completion!
The final step is plugging the low voltage connectors into the coil packs. Now the vehicle is ready for the road!
