Re: confused about spark plug cables
No answer your question you could put the copper wire into the end but the chanc of it workin is about zero. The conductive material in the cable that you got from autozone is the black wire you decsribed if you have the spark plug wire I think you have. The white fiber is just a figerglass like material to support that black wire that is really a carbon based to carry the current. This is in place to reduce the electronic emmision for todays cars. Some others may chime in but if you have the wire I think you got then this is why there is no copper wire.
One question for you is why did you not just use the new spark plug wire cut to size with the boot attached? Just unscrew the old one from the cdi and screw the new cable in.
