They get tighter with age, not looser. They are prone to light misfire when out of adjustment.
I am probably swimming in misfires. Still on OEM plugs
Let me tell you a story about the (J35 equipped) Saturn VUE that I got to swap an engine in, after one of the OE spark plugs somehow got loose after 150k, and it destroyed the cylinder head.
Because these things happen in pairs, a month later I got a Pilot in that ate its engine in the same manner.
