well sorry mister high and mighty for posting in the WRONG area. and for your information it wasn't some blingy infomercial that told me about them. It was an actual show where they did compare them to stock conventional spark plugs. and yes they did out perform those conventional spark plugs by using less fuel to give more horsepower. so to ask my question again. has anyone ever heard of them or used them before and what are your thoughts on them?
