NGK make Iridium plugs to if you MUST have them (and they are only $6 each - much cheaper than Denso). I had them on my car and they didn't feel any diffrent, really. I am now using the cold Motorcraft plugs that Demon suggested. I forget the number, but I had to order them special.
When I install the turbo I will be using NGK TR6's though.
If you want I still have the iridiums and can send to you for $10, if you wann try them. They are still perfectly fine.
I ran Tr6's for two years, and STILL have them in the tool box. They look fine,; good plugs.
I also run the plats as stated above and they are a bit better on overall hot/cold-winter/summer driveability I think. No problems and I assume Ray isn't having any problems still. Anyway, they are stock plugs so the ignition system runs just like stock so that is a plus.
