I also a 2003 ram 1500 5.7 liter hemi. I put MSD high performance coils last Sat and MSD plug wires yesterday. Im also running Baush plugs and cold air intake.Just looking for any advice on coil packs. Got a couple on the 2003 ram 5.7 that the sides are separateing and plastic coating is off just on the sides.
Truck seems to run great no probs though. Any way wich brand, looking for input on this.
And if the coil packs are still working fine should i even replace them, hate that they look bad on the sides though.
Thanx
