American vehicles run on voltage. You don't need anything larger than 8mm unless you are going the amperage route. I run an Accel coil pack and 7mm NGK wires on my Splash and it does great.

If you have a coil pack, you have to get wires for a coil pack. They have clips that hold them into the coil pack, and are entirely different than the dizzy cap connections (male vs. female). If it's for your 4.0, then you need coil pack style.
