Default Re: confused about spark plug cables

What you have is resistance wire and what most auto parts stores sell today. Copper core wire is better than resistance wire for our little engines. There are some resistance wires that have been said to be as good but you won't find that at your local car parts place. If your kit supplied wire has a copper core, stick with it. If you want to go with resistance wire you'll need to look for a high performance wire intended for racing applications.
The reason for resistance wire is to reduce or eliminate radio interference and in today's cars, to protect sensitive electronics from the RF interference from the high voltage leads (spark plug wires). The two can not be spliced together. In fact you should never try to splice a plug wire.
