I have to change the top plugs now, truck is an 08 4.7 16 plug motor. Had the top plugs changed at 30K by dealer, they destroyed 2 coils. I have to replace a coil due to a misfire P0303 misfire cylinder 3. Is there more than 1 bolt holding on the air resonator? The rest I am pretty familiar with, I think thanks for any tips on removing it. I ground down a socket to fit in the plug hole, seems to work well, any one know where to purchase the correct tool other than the dealer for 80 bucks.
