I just finished changing all 8 plugs. 2006 5.4 with almost 70,000. I managed to break 4 out of the 8, but overall the job wasn't as hard as I expected thanks to the guys on this forum and the how-to section. I highly recommend anyone attempting have the lisle 65600 on hand because its a life saver and works like a charm. I broke the 2nd from front on the driver and all on the passenger except 2nd from the back.

The worst part of the whole process for me was the 2nd from front on the passenger the nut and threaded section came apart and left the entire porcelian and electrode intact. I had to use a pair of needle nose to snap the top section off to be able to use the lisle. The next thing nearly gave me a heart attack but turned out to be nothing was I forgot to plug the connection from the throttle body motor back in. The truck idled like crap and shook like crazy, but I plugged it back in and reset the computer and it was fixed.

To anybody who wants to try the plug change but fears breaking a plug get the lisle tool and dive in. I would like to thank the members of this forum again and now I need a beer and a shower.

 

Pictures or it didn't happen.

Kidding thanks for taking the time share your experience on spark plug removal and installation

 

Good job. Now you know how to do it. There have been alot of successful plug changes on this board lately. Which is a good thing.

 

hmmm do you guys think I need to do one? Im at 70,500miles on my 5.4 and on the freeway going around 60-65 at 1800-1900rpm the truck is shuddering

 

Just for you OGTerror. Sorry they crappy quality cell phone pics though. 2nd pic is the one I had to use a magnet to remove the hexed/thread part then break the upper porcelian/electrode section from the lower porcelian/shield to use the Lisle tool.

Also, I'd like to add I got Motorcraft SP-515 for $7.99 at my local O'Reilly's when Advance wanted $7.95 for the SP-507 model. I read the sp515s are double platinums which are supposed to last longer than the sp507s singles.
