I changed mine out today. I have 9909 miles on my 06. The S/C has been on since 3300 mi. The pic shows what they all looked like. They all came out with no problem. I turned them all by 1/4 turn, as the TSB states. All but the rear passenger side spun by hand at that point. I went ahead and squirted some PB Blaster down that hole and waited a bit. After that, it too, spun out by hand. The plug on the far right is that particular plug. The line where the carbon stops actually has somewhat of a ridge to it. Obviously, this is where the build up occurs.
The socket size needed for these is 9/16. I have a socket made just for Fords modular engines,but it was too big.
Nickel anti-seize was applied to new plugs.
