Hey guys, so I did the plug change on my wife's 05 5.4 expedition, bought the removal tool, broke 3 plugs. Overall it wasn't a terrible experience, I've done the job on 2 other 2v motors before so I knew what I was getting in to as far as plug access and how many extensions and u joints I'd need, no big deal. Now, my dads 04 5.4 needs a plug change. The part number for the 04 plugs is different than the 05. I know they did a head change to fix the short threaded plug problem, but I don't know what years. My question is: does the 04 have the same plug breaking problem as the 05, and will my lisle tool be compatible. PN for the 04 is sp479 05 is sp515 Thanks! Sent from my iPhone using Tapatalk
