You are fouling your plugs out either by burning oil or running too rich. If its due to oil you can either replace your rings and valve guide seals or there are people that make cheap inserts to pull your plug end farther from the combustion chamber reducing there exposure to the oil. If you are running rich, it is probably because someone "tuned" the car crappy. Good luck
