I recently changed out my spark plug wires and only now noticed that they are 7mm. I was reading random threads just to learn a little more about what I really need to mod a little. I think in the Canadian Guy's signature was safely modding your car link and it mentions spark plug wire ranges from 8mm - 10mm. I have a feeling that I will need to replace them to a bigger range eventually. My mods are: Air Intake, Shift kit. Will 7mm be ok to run with minor mods?
