On "Cartalk" recently it was suggested to change your spark plugs early as a preventative measure (before 100k miles).
One board member on another site mentioned:
The spark plug design on 3-valve engine is different, ... the problem is that the spark plug threads actually protrude through the cylinder head into the combustion chamber. After 100K miles, there can be quite a bit of carbon stuck on the threads. Try to remove the plug with all that carbon on the threads, it seizes, breaking the spark plug off way down in the head if you don't stop.
Some members of this site have suggested this is one job that is worth paying a Ford dealer to do ($300+) ... so you aren't the one to destroy your threads.
How many of you guys are thinking about changing your plugs early?
Do you expect there is any chance that Ford would offer and TSB or similar remedy so owners don't have to pay for this service?
