What would be a better than average spark plug for a relatively stock 2007 Mustang GT 4.6L with only minor upgrades. I have OR/H, CAI, and a tune..

I have the stock plugs in there now and yeah I know about the problems changing them but looking for a suggestions for a real good spark plug.

NGKs are what some of the modders around my town use on the 4.6L engines.

These seem to take some serious abuse too, from supercharging, lean/rich mixtures due to custom tunes, to nitrous, and more.
