I'm not going to bash another manufacturer, but one set dropped my gas mileage 2mpg over several tanks. I'm wondering what difference the resistance of the wires really makes. I'm not an electrical engineer, but I do know it has to have some effect on the performance of the ignition system. I've seen spark plugs cause some cars to run like absolute crap, switch back to the ones that came in it and everything is fine. It's pretty hard to have the time to do back to back dyno runs and swap them out unless your friends owns a dyno.
