Re: Stuck Spark Plugs

Because the aluminum will also cool and contract faster then the steel of the spark plug. Thats when you run into problems of stripping threads. If you do it when both parts are fully heated it might be ok (not sure if one expands more then the other) but rarely does anyone change plugs immediatly after shutting off the engine.
