Default 7mm or 8mm?
So what would be the difference in using 7mm spark plug wires to the 8mm wires I have the 7mm, I am wondering what is the difference?

With a stock ignition system, there is no difference. If you had an MSD or other aftermarket ignition, the larger wires would give you more insulation and help keep the spark from escaping.
