Thread: Spark plugs and wires

Hey I have read the article about modding your gtp but I would like a clearer answer on something. Don't use iridium plugs with super charged cars? My car has 130,000 easy miles and needs a tune up(slight miss.) I AM NOT GOING RADICAL, Daily driver. Most i see myself doing horespower wise would possibly be CAI. With that said, which plug do I want to use and 7mm or 8mm wires? I have already changed fluids and filters prior to that excellent article, and I mean it. That was a very good article. Thanks for the help. Like everybody, I am trying to save money but I get a really good discount at the local parts store. I just did not want to by something that would hurt the motor. By the way, I pulled plugs that are in it. Not original AC 401's that showed signs of wear.
Thanks for the help.

Thanks for the help. So the iridium wont hurt the motor?

Thanks I think I will save some money with the delco platinums.

If you're going platinum plugs go with AC 41-932's. They're 1 heat range colder. So even though you're not modded or won't be modding heavily it might cure any kr you have right now.
