Will it hurt my Jeep Grand Wagoneer to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

Engine Tune-Up for Jeep Grand Wagoneer

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jeep Grand Wagoneer engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your Grand Wagoneer. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your Grand Wagoneer. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Grand Wagoneer: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
