I have a 2006 GT with 27k on the clock.
Still have the factory two piece Motorcraft plugs in it.
Should I change them using the Ford TSB guide lines?
Or, should I have my trusted local Mustang speed shop do them?
Knowing that they have the experience and the special extraction tools that might be needed.

Yesterday I took all the Motorcraft sparkplugs out without breaking. It was the most stressful motorwork operation I've done. I used carb cleaner that was on the shelf (Valveline) and sprayed it to the hex nut level. Then it took over 40 ft lbs! to crack them. After they were each cracked I went back and did an 1/8 turn on each one let it soak 20 min then another 1/8 turn After about 3 hrs I got them all out. During the process some plugs felt tight and others felt very loose. The loose plugs I thought were broken...that was the stressful part. Thankfuly none of the Motorcraft plugs broke and the new Champions 7989 with nickel antiseize are in. Glad I don't have to sweat another sparkplug change again.
