Oh, and "colder" plugs really are physically colder under hard conditions. They absorb less heat from the combustion cycle, which makes them less hot when that cylinder is on the intake or compression stroke, and they cause less pre-ignition. The downside is they foul more when you aren't getting high EGTs. Tuners pretty much universally think that's a good tradeoff, as long as you aren't fouling them so bad you get misfires when you do go WOT again.
