I had the other issue with my 5.4 plugs.
Truck was bought used and had the sparkplugs replaced previously. Whomever did it overtorqued them.
I had overtorqued sparkplugs that blew out of the heads threads and all. Sounded like a God dammed IED went off. A shop vac with a homemade nozzle, shrink wrap stepped down incrementally, a heli coil, and a new plug and coil were necessary each time.
Got pretty good at it. By the third time I probably could've done it on the side of the road. But driving it home with an open cylinder was always fun.
Be aware that @NotBudule and other users have found that the actual point of entry is probably at the cowl. It seems water drops there, lands on the top of the block, then settles in from there.
The cover might not really do anything. It was originally designed to mitigate sound, not water. Which is why it was only standard on the Lariats.

I like this idea.Hmm... maybe a shot of WD-40 in the spark plug well at each oil change might be prudent.
Since we live in a semi arid climate here, it's probably not an issue. But I wonder if the OP's problem was exacerbated by living in Texas near the gulf... which means high humidity and higher corrosion due to salt is a likely probability?
I ordered the cover, studs and nuts from a Detroit area Ford dealer that sells online. They had the cover, but were warning that the studs/nuts didn't fit my '22. I see elsewhere that they are OK for the '22 and since they are called out on the TSB, I ordered them anyways.
I decided not to wait for rust, codes, etc. An ounce of prevention is worth a pound of cure.
I had thought that this cover was purely cosmetic until I read this thread and the referenced TSB.
I don't know if this cover delete was a parts shortage issue, or the handiwork of the Ford beancounters, I suspect the latter. This wouldn't be the first time that a cost reduction went awry.
Thanks for posting this info about the issue and the fix.
