HI I know it seem early to think about spark plugs, but I was wondering about putting in better that oem. I believe that you have to take off the intake manifold to get to the rear plugs. Has anyone replaced the plugs and might know of an 'easy' way? I have 30,000 on my 2008 Edge Limited and no problems. I think the chrome plastic wheels on the limited cheap. I will add new wheels when the tires wear out.
