This is not a problem when plugs are change dby a mechanic that know the engine.
My Ford mechanic told me that when they replace plugs they break the plug about 1/8 of a turn then soak the plug hole with something like WD-40 that over night penetrates down the threads to the spark plug tip and softens the carbon built up around the spark plug tip.
Now the spark plugs don't need to replaced until 100,000 miles so I don't worry.
I do add this stuff a few times a year when travelling at highway speed to reduce carbon build up on plugs and valves.
You can pick it up at Walmart or any truck stop.
