Default Re: Spark plug wire and boot.

One thing that wasn't mentioned here is when looking for high performance plug wire you want a metal, preferably copper conductor. Most spark plug wire offered by the leading auto parts dealers today is resistance wire (TVRS). It has no metal conductor but instead has a carbon impregnated core, often a cotton or nylon thread. The resistance wire was designed to eliminate radio interference and has high resistance and therefore not the best option for small, low voltage ignition systems like ours. Hot rod shops or those catering to the race car folks, even lawn mower shops will have copper conductor wire and most will sell by the foot. Just something to keep in mind. If you have doubts about this and have access to an ohm meter, run a resistance check on a foot of copper core wire and a foot of resistance wire. You'll be amazed at the difference.
