Default Re: Need to replace Plug Wires

Radio or ignition...

If link doesn't work. Think most will agree if not they can disagree.


First off, your particular ignition system will tell you what type of plug wire you should or-more importantly-shouldn’t use. Early points-style ignitions and magnetos used low-resistance wires to carry a lower voltage as compared to modern systems, which can easily carry up to twice the load, thus requiring a higher tolerance wire. Running a modern, spiral-core suppression wire with the early ignition can actually decrease the voltage being carried to the plugs; running the early solid-cores with a high-output (breakerless, capacitive discharge, or HEI) system can easily result in damaged electronic components for the exact opposite reason. There’s more to a plug wire than the color of its skin.
