Spark plugs, like motor oil, fuel filters, and air filters, need to be maintained on a regular basis in order for your engine to function properly. The majority of cars purchased in the United States are required to have their spark plugs changed every 30,000 to 50,000 miles.
However, some modern vehicles have more sophisticated ignition systems that imply spark plug replacement is no longer required. Regardless of any warranties or claims made by a vehicle manufacturer, there are occasions when a spark plug deteriorates or exhibits symptoms of failure.
