    leave the coils and wires stock. they perform just as good, if not better, than anything else on the market.

    when you say autolites, do you mean the xp extreme performance iridium ones? i am picking up a 99 gtp on monday and always do a full tune up on all used and even sometimes new cars that i acquire. Not trying to steal the posting or anything, but figured keep it in the same thread as it is pretty much the same vehicle. Thanks in advance!

    just go the auto parts store's counter and ask for Autolite 606's or 605's copper core plugs. They are like $1.50ish each or so.

    Sorry to jump into this thread but i just recently needed to replace my plugs and i found walmart sold the autolite APP104 double platinum plugs. I put them in a felt a good difference. Are those the 104s people are talking about? just curious is i got that same plugs or if getting a set from zzp would be better?

    Autolite 104's can be bought from any "Auto-Parts" store such as Autozone or Orileys. Getting your plugs from ZZP would just be a waste of shipping costs.

    AP's are single platinum.

    104's are for modded cars.

    for modded cars ideally you'd use copper and of the appropriate heat range.

    you'll enjoy going stock...ive used "different brands" before in my other vehicles rather than stock and it would misfire and get terrible gas mileage...changed the plugs back to stock and good as gold!

    And should come gapped to fit ur car
