I used to own a 2007 150 with the 5.4 Triton motor in it and i took it to the dealer to have the spark plugs changed because of the history of those plugs breaking off in the heads. Sure enough, the guy had two plugs break when he tried to take them out. My 2013 has the 3.5 Ecoboost motor in it and im wondering if these engines have the same issue? The truck is at 78,000 miles and id like to get them changed soon. Just wondering if i can do it myself without breaking them or if its worth the money to just take it in.

It's an easy hour job if you have basic tools. There is a really great spark plug tool you can buy that has a magnet on the tip and has just enough swivel in it to get to everything. You only need a 8mm socket to get the coils off, then buy a set of 6 Motorcraft SP-534's from RockAuto and this special tool. It will make your life much easier.


I can change plugs in about 30 min now with that wrench. At 78k miles, you more than need it done.

Also....No, they are not the same stupid multipiece plugs.Straight up normal style like used for most cars for decades.

Thanks guys!! This makes me happy. I think i paid like 400 bucks to get the Triton plugs changed. New plugs for the Ecobeast are gonna be like $40. Waaaaay better.

Changed the plug in my '13 Ecoboost for the first time at over 100,000 miles.
Absolutely the easiest plug change I've ever done and I'm no Spring Chicken. Changed a lot of plugs over the years!
I used a piece of rubber fuel line on the end of a screwdriver for a plug removal / installation tool.
A swivel socket gives a little more flexibility also.
Took maybe an hour start ti finish.

Thanks for the tool recommendation! I just rolled 50,000 miles and will be doing plugs for the first time.

Hardest part is disconnecting the damn plugs to the coils. I think I broke 3 last time I changed mine.

Also, check gapping. .030" is the ideal gap.
You will most likely break the red tab. I think I don't have any anymore lol

Apparently the Sp-534s have been superseded by the 580s. I never knew that. Anyone know the difference???

Not entirely sure what the difference is, but that is what i put in my truck about 5k miles ago. Seems most needed to regap the 534's, but all of my 580's were already very close to the 0.030" gap that everybody seems to recommend, so i left them alone at the gap they were delivered.
