I took my 2002 Ford V10 in for new spark plugs, cost est. was $300, service mgr. said the V10's do not brake off, but the V8's can be a problem. They have to work V8 plugs back and forth with 30 lbs. of torque to remove then. The cost for the V8 was $500.
I have a 03 F-150 with the 5.4 liter V8. It has less than 50K miles on it and will probably die along with me, having the original plugs.
They certainly will never be changed, unless one goes bad and begins to misfire, that's for sure.
As for replacement costs, it's ridiculous and only because they want paid ahead of time for all the jobs and just in case they do break one, once in a while.
