Well I guess it all matters on what you want to spend. A good 8mm set would be tops but you can probably get by with a cheaper set. Just be careful routing the wires so they dont hit anything hot or where they will rub.Buy some wire looms to help ya out.Back in the old days I would go out at night,pop the hood,fire it up,and watch the light show coming from my old plug wires.That would be replacement time. Also if the wires werent fitting tightly is there any change they came off and somehow got switched?
