Plug Wires

Any type of plug wires degrade over time and can eventually "leak". Heat, fuel, oil, humidity, etc. affect everything - including radiator hoses, belts, etc. Thicker wires tend to have more insulation and should last longer. I've been using Accel 8.8 plug wires for years with a Mallory HyFire VI system on my race car with great results. But they have a wide variety to choose from.
