Others have touched on this point, but I'm wanting to clarify it a bit.

Because of the metal in the electrode, there is fewer volts required to create a spark, and so for the same amount of power, you should get a hotter spark. A simple copper electrode cannot possibly hope to do that.

I'm hoping this bump will override the discussion on plug indexing, which sounds more like a sale for snake oil.
