In theory the plugs in almost any modern engine should last about 100,000 miles, thanks to all the computer stuff and better metals to make plugs out of.
This sort of compounds the Ford crimped spark plug problem, cause after 100,000 miles there is a LOT of carbon baked onto that plug! BTW the plugs looked real nice, even at 93,000.
