I used Magnecor wires on my '03 GT and they worked well. I used stock copper plus plugs gapped at .040 and my 280 hp GT ran very well. Irridium plugs are overkill, more expensive and do nothing for performance. Friend of mine ran stock plugs in his PT turbo at the track, switched to irridiums and there wasn't a bit of difference.
