Ok, let me start this by saying done a few frame off resto's on old school trucks and cars, spent a while in the military as an engine room mechanic working on dual 12 cylinder 24 piston 18,000 hp motors... I'm decently mechanically inclined, but I learned something new tonight working on my new to me 2010 F150. First 2 plugs went down quick 5-10 min each... Plug 3 the socket wouldn't bite, nothing worked... Pita location to see what was up, especially standing in a step ladder.... Finally used my phone to snap a picture and saw a pebble or something was blocking the socket from getting down... Tried a small flat blade, couldn't find my gun cleaning pick so made a hook with a paper clip, tried a pencil, tried scissors, drank a beer, tried wire... Drank another beer... FINALLY busted out the air compressor, blasted a ton of air into the channel and after a few minutes, and a TON of dirt everywhere (seriously the engine bay looked show room when I started didn't know there was that much dirt hiding by the boots) the damn rock flew out.... after that I went crazy with the air compressor around every boot , needed to repeate the process on one other plug, but over all 2.5 hours to change 8 plugs with 1.5 hours on a single plug... The air compressor is now a MUST HAVE on any spark plug job on this motor!!

Your lucky you did not have the old 2 price plugs from the older 5.4... talking pita.

Air compressor/blow out pretty much standard with the new engines having the spark plugs recessed in wells.

Remember to apply fresh silicone grease to the lips at the top of each boot so water doesn't go down there. And a dab inside each boot (NOT on the metal) to keep the rubber from sticking to the ceramic.
