what year car do you have? 99+ is COP, so no wires to worry about. I had MSD wires on my 97 cobra.. Copper plugs seem to be what everyone goes with here, especally the boosted guys. Most people go with the NGK's.

NGK TR-55 with FRPP 9mm plugs.
Just installed them on my own car.
I actually gapped my plugs a little lower, 0.054 is stock but I put mine around 0.049 or so and it runs great. Just out of curiosity I checked the previous plugs which I assume to have been stock, they were 0.08+! The car was noticeably smoother at lower RPMs after I changed the plugs. Haven't driven it with the new plugs yet but they should help too.

ORIGINAL: SXGT
near stock , it wont matter so much as long as it isnt AUTOLITE or Kmart brand. NGK is the best but i use BOSCH Plat.
