Check your owner’s manual first. In general, though, most spark plugs last approximately 80,000 miles. Many auto advisors recommend replacing them after about 60,000 miles to avoid problems as they begin to wear. Bad plugs will give you decreased fuel efficiency, a loss of engine power, and eventually a car that won’t start at all.
Don’t drive a car with these kinds of problems. You can damage the engine. Broken pieces of spark plugs can get inside the engine and will affect other components, too. Bring the car to Tire Works Total Car Care for a diagnostic check. We will identify the problem and advise you on the best course of action.
