I'm actually dropping back to the vPower BKR7E copper plugs. The 8EIX are the best of the iridium plugs but not as good as the copper plugs.

My experience is that the coppers should last about 15K miles for me. The 7EIX only lasted 20K and were significantly more expensive and not nearly as responsive as the 7EX. I have a set of 7EX sitting in the box so when I pull my 8EIX this weekend I have a backup set if I need to replace them. I'm getting spark blowout at WOT starting around 3K RPM.
