For those interested, I recently changed the plugs on my PB. I got the initial set from a major dealer, but they were wrong because mid year in 2021, Ford switched from tapered seat to a copper gasket. FordTechMakuLoco has a great video on this, and THAT was my resource for finding the correct part number, which is SP596, with "DYFS12YPT" written on the plugs. The new plugs are visually easy to distinguish as they have a copper gasket vs a tapered shoulder just above the threads on the old plugs (and really, this is only an issue for MY21 trucks as everything since ~July 2021 is the new style).
Overall the job was really easy, though it was the first time I have used a torque wrench on a spark plug (set at 18 lbft for the new plugs). Every plug except for the rear passenger plug was very accessible though I recommend having 2" and 4" 3/8" extensions available (too long won't fit on the rear cylinders so you really need both of these extensions to get at the plugs), as breaking the initial seat on the factory plugs takes a bit of force and stuff is in the way. Other pro tip: pull all of the coils and boots at once and reinstall at the end. I found that the coils get in the way of replacing the rear cylinders, moreso on the passenger side. At 63k miles my boots looked essentially new, and while they are cheap they are also tough to find. Finally, the benefit of doing this yourself is that you will apply antiseize to the threads, such that the next time the plugs aren't a battle to break loose.
Overall, an easy job if you have the correct extensions handy AND got the correct parts beforehand. Hopefully someone will have an aftermarket coil by the time that I replace the plugs again.
