Lexus IS F racing spark plugs use capacitors inside each plug to concentrate energy to 1,000,000 watts, instead of the normal 50 watts. This creates more horsepower and greater gas mileage. Owners who already use these plugs say they really work great, according to IS F spark plug reviews on the lower section of our pages.
