From what i have heard run seafoam through it and let it set for an hour or so before removing plugs.

Seafoam will help but be prepared to extract some broken plugs. Go ahead and buy the broke plug removal tool, especially if you have over 100k miles.

Do yourself a favor and pony up for the one piece plugs (champion) they are about $19 a piece.

I can't agree with this, my opinion is it's BS. The two piece design of the plugs plus carbon build up is what breaks them and it doesn't take much.

Like I said....my opinion

you watch the video? I wouldn't have believed it either cause I've had friends with Harley trucks and those are a PITA to change plugs on...just watch the video, obviously this guys done a $H!T TON of these since he's most likely a FORD tech...but still.....those guys get book value for jobs, they are going to find the EASIEST way to do something...
