I am a firm believer in Ac Delco plugs in GM vehicles but at out shop we have had GREAT results with the e3 spark plugs in gaining economy. I recently put a set in my 98 Deville and I lost about 2-3 mph. Has anyone else tried them and if so what was the result? I am looking to make this deville as efficiant as possible for a project so if anyone has any ideas of things that they did that made a diffrence economy wise please post I would love to hear about it. My car is all stock at this point, but I am looking into changing that as well. Thanks
