Based on how often a vehicle is used and the kind of the car, spark plugs should be replaced in intervals of 20,000 to 100,000 miles. Old or damaged spark plugs ultimately cause engine damage. Hard starts, reduced gas mileage, engine misfiring, and lack of acceleration are the symptoms of defective spark plugs.
