Hey BackroadBomber,
That's great that you are going to give it a try. I don't think you will see instant results with this, only under those limited set of circumstances when pre-detonation would occur. As has been pointed out, that is probably more likely if you have a grille block or other mods to keep the engine hot.

@KSA8907, disconnecting the battery is required after installing the new plugs to clear the ECU of those situations it has already learnt when pre-detonation occurred with the old plugs. i.e. to give it a fresh start and learn the new parameters.
