My brother has a '99 intrepid with the 3.2L V6 around 120K miles. He has a "hot" cylinder. ie... he put in a new plug a while back and about 2 months later he was inspecting them and one was all white with residue. What causes this? All the other plugs are nice and clean.

I would lean towards a vacuum leak. Faulty injectors tend to have a poor spray pattern and the fuel don't atomize correctly which don't burn good giving a rich condition.
