Hello. If you continue to have the spark plug end burn up on just that cylinder then there is an issue with the mixture in that cylinder. It can be caused by a compression problem, carbon build up, or it can be a vacuum leak. Most of the time it is due to a valve seat issue in the engine which can cause the mixture to be off enough to cause that cylinder to run hotter.
