The consensus seems to be they are all pretty similar -- performance wise. I'm happy with the NGK Iridiums. It's a pretty easy driveway/garage job.

What about the 4 prong ones that you don't have to gap?

AC Delco Iridium plugs and GM performance wires are a great combo.

Good choice!
Gene can hook you up for 100 or so for plugs and wires.
Easy? 7 can be a hassle. Just get new wires, you need them and will probably FUBAR at least 1 getting them off. They tend to be stubborn. 2 hints: wear gloves(!!!) and be liberal with the dilectric grease on the new wires.

I went with the AC Iridiums when I changed plugs. They are very good and got them at a great price from Gene at gmpartshouse.com.
