So maybe this is a stupid question, but, iridium isn't platinum, is it? i'm reading all over the place that iridium is BETTER than platinum, but is not platinum. so if the 5sfe requires platinum plugs, would iridiums be bad? also, is there a difference between iridium, and iridium ix?

stock plugs (at least for the 3sgte) are platinum. They generally last a pretty long time - much longer than standard copper plugs. Iridium are much more expensive but last a VERY long time. Iridium are as good as copper at conducting but last longer. The down side to iridium is that the tips are brittle and can break - particularly with higher horsepower applications. In a stock application, a set of iridiums would probably last you the life of your car. Platinum is almost as good at conducting as copper and iridium but not quite. These are all generalities.

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.
