I was watching Horsepower on spike tv and the new E3 spark plugs were shown to improve results on the dyno...I'm changing my plugs very soon and wondering if people think these are worth paying extra for. The company claims they improve power, fuel economy and reduce emissions. What do people think, are they worth the hype surrounding them? check it out: http://www.e3sparkplugs.com/
