Default Fouling Spark Plug?

Hi I have replaced my spark plugs three times in the last month. They seem to keep burning out and turning black. The engine will then loose acceleration. Has this happened to anyone before?

If your spark plugs keep getting fried and you besically have a stock car, try getting a new brand name spark plug. Denso are great, will give you alittle more hp also. If you put these in and it happens again, id deffinetly take it to the dealer
