Just about any of the top of the line wires will work. I have used MSD, Accel, etc. 50ohm per ft. And yes gloseing the gap is a great Idea. What is happening is this. Our ignitions are called waste spark ignition. When one cylinder is firing, it's opposite cylinder(that is on the exhaust stroke) fires at the same time but in opposite polarity. So if on the compression stoke there is a miss fire, it will get another chance to fire the unburned gases on the exhaust stroke. POP! Why will it fire on the exhaust, and not the compression stoke? For the spark to leap across the gap in open air takes a minimum amount of energy. As comperession increases the energy required to produce a spark also increases. You can either increase energy to compensate or close the gap required for the spark to jump. Keeping your ignition components in top shape is a must in a boosted application. As boost goes up, so do the requirements of the ignition. If you know your plugs and wires are good then you move to the coil, and on and on from there until you get to the passenger side back up light which is the end of the line in ignition diagnosis. Ha! Hope this helps. Danny
