Some DO get stuck, even in the other engines in this family.
Even if the plugs are suppose to go to 100,000 miles, I prefer replacing(or even checking them sooner) just so they will come out easier when you need to change them.

Plugs are cheap, so there is no problem keeping them new(in my opinion).

Water and moisture that gets trapped in the sparkplug socket seems to be the culprit.

When replacing your sparkplugs use a dab of anitseize on the treads, this procedure will save anguish later on.

Also checking your plugs will also keep the sparkplug boot from sticking to the sparkplug(a lube for this is also available).

So yes it can happen, but a 64,000 benchmark is not a standard.
