iridium or platinum plugs

Which is better for MPG/performance or is there not much difference?

No difference except in longevity.

i say go for Coppers. They are a lot cheaper and they conduct electricity better then irdium and platinum do. But they only last 20,000 miles, but they are 4-5 times cheaper.

This statement should be a sticky. I say 30k though.

Aren't the ones next to the firewall kind of difficult to get to? At least on the 3.5L engines? I haven't done mine yet but will be in the next few months.
