I will tell you this. there is a product called deepcreep that is like magic on stuck bolts/bearings/keyways and all sorts of other stuck situations. if I had to do this job, I would spray each plug while the motor is still warm and let it soak over night. I would then start with the easiest plug first and work from there. I would also buy the extraction tool in advance. good luck this. But we used pb blaster. Get Moyer hot and spray each plug down good and let it soak. I haven't broke one but have seen it several times. Pay close attention. good luck.

buddy of mine said to spray with PB while hot, wait an hour or so and use a impact wrench to loosen the plugs. Prayers sent. Sorriest POS example of Ford engineering in a very long time.

I never changed mine in my 04. I thought about doing it but I started hearing all the horror stories about them breaking and so on. I said nope. Mine was an 04 that ran like a dream. Never had a bit of problem out of it.
I even checked the stealership and they said they couldn’t guarantee and breaking. Then they would have to remove the pieces at additional cost to me.
I would rather be tried by 12, than carried by 6.

We warm up the truck, crack all the plugs loose a half turn soak with kroil, wait an hour and use a 20 impact driver. Almost never break one this way.

What year is the truck? If it's an 08, what is the date of MFG? Asking as the FFV 08's like mine have different design heads that utilize one piece plugs. They are a whole lot easier to replace.
Using any replacement coils other than Ford usually ends in disappointment. A very good thing to do is replace the boots and inner spring. Be sure to clean the contact point where spring meets the coil with emery cloth or similar.
If they are two piece plugs the above recommendation using Kroil is as good as it gets.

I first changed my 2006’s at 100,000 miles. On Amazon for $180, I bought the Lisle extraction tool, same oem Motorcraft 2 piece plugs, nickel anti sieze, cop boots/springs, and dielectric grease.
I warmed the engine, cracked the plugs, sprayed PB and set up overnight. Next day I tried an easy to reach one to get a feel for it. I broke it really quick because I forgot to turn down the air pressure for the impact gun. The other five easy to reach went great but I broke the back two. I spent a bunch of time getting the three broken ones out using the tool (which does work well), and vacuuming the cylinder with a small vacuum tube. I used anti seize compound on the lower part of the plugs and got em all in. Then installed the cops/cop boots and springs with dielectric grease.
Worked like a champ for 80,000 miles til I had my first cop go bad. I cheaped out by buying a cheap set of 8 cops from Amazon for $40. I replaced all of them versus just finding the bad one. I kept all the originals because I’m sure if one of the cheapos goes bad then I can find a good oem one. Since I was gonna be in there I did the plugs 20k early. Man it was so easy because of the anti seize compound. That was over a year ago and a bunch of miles still going strong. I love this freaking truck. I hate that some have had bad experiences but not me.
Sorry for the long post, good luck. If you were close I’d be glad to help. My shop is slowly becoming a more organized nightmare. Some day I can see being able to work on something out there.

Do you have a miss or CEL No codes. Just when I go to accelerate real hard it starts to pop and skip. Mostly from a roll to 15 mph. Just put a new TB on it last week. Problem was there before TB install.
