Has anyone tried these? I was just wondering because it does make sense.

they tested out a few cars and the MPG went up from anywhere from 3-10% Not bad, and HP went up and acceleration time.

Look legit? I think they wont really do anything except gas mpg since the stock plugs so make enough power?
I sense a experiment.. :P Also they have a 30 day guarantee
