2 piece spark plug

As far as a repllacement plug, as long as you put nickel anti-seize on the new plugs they will come out much easier in the future. I would also replace them a little earlier as far as mileage. I have heard nothing good about E3 plugs including my own experience with them in numerous vehicles.....stick with either OEM Motorcraft or Champion plugs.
