They hype is around the HP gains. The fact is that they do not run "hotter" than the NGK. They will help improve your gas mileage. You will get a minor boost in horsepower until your ECU corrects the fuel air mixture. At that point you will see the gas milage gains. Buy them direct and they will offer you excellent customer service. One of my plugs broke during install, they overnighted me 2 new plugs... Great customer service and real MPG gains. You might see a little more pep in your engine, but there will not be any huge HP gains...
