cryptnix Posted May 5, 2004 Report Share Posted May 5, 2004 Whats the deal ... Why are these so crummy? (Platinum) Everyone says AC Delco's better... explain to me why.... Quote Link to comment Share on other sites More sharing options...
kanwisch Posted May 5, 2004 Report Share Posted May 5, 2004 My platinums were absolutely horrible, and resulted in misfiring in at least one cylinder. AVOID THESE PLUGS! In fact, I've seen lots of notes regarding platinums in general, and the suppositions were that they couldn't handle some of the higher heat ranges; don't know the facts on that for certain. Iridium is what I replaced them with, and no problems since. Quote Link to comment Share on other sites More sharing options...
gp90se Posted May 5, 2004 Report Share Posted May 5, 2004 Platinum are fine as long as you run higher octain gas every tank. Platinum tend to foul out more then normal ones with 87. I run the rapidfires because they seem to run hotter in the NA car and I run the colder plugs for the TGP. -Jeff Quote Link to comment Share on other sites More sharing options...
jacktgp90 Posted May 5, 2004 Report Share Posted May 5, 2004 the plats last longer than the ac delcos, but the plats don't give as much of an intense spark as the ac delcos,or any other copper or nickle sparkplug. platinum doesn't conduct electicity like copper or nickle.

god910 Posted May 6, 2004 Report Share Posted May 6, 2004 A common misconception, platinum plugs are NOT performance plugs!!! Platinum plugs are a longer life plug designed to keep you from having to change your plugs as often. I would stick w/ stock AC's. Quote Link to comment Share on other sites More sharing options...

I would stick w/ stock AC's. they still wear down though. the platinums i pulled out with 30 or 40 thousand on them were gapped way oversize Quote Link to comment Share on other sites More sharing options...
