I've changed quite a few plugs over the last 30 years years and none have ever been seized. I live in the rust belt too. Not sure where people's fear of plug seizing comes from in the first place.
I'll tell you, from Ford service! My 2010 6.2 is there right now for a check engine light warranty fix. They just called me and said that because it's @ 90k the plugs should be changed while it's there. I asked for a quote on it; roughly $8 a plug plus about $300 labor. That was assuming none were stuck and if so, broke off. He then went on to tell me the horrors of stuck plugs breaking off resulting in the need to pull the heads to the tune of 2-3 grand bill. I said, no thanks I'll take care of it to which I got another doom and gloom lecture about how that they should have been changed at 60-70k, now at 90k they're going to be trouble blab blab blab.
My last F150 had the 5.4 with aluminum heads and I changed them no problems.
Anybody here have, or know of anybody that had stuck plugs in their raptor that broke off while changing them??
