Will it hurt my Mercedes-Benz CLS550 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.

What does a puddle underneath my Mercedes-Benz CLS550 mean?

Are some driving habits better for my Mercedes-Benz CLS550 engine than others?

Tune-Ups to Help Your Mercedes-Benz CLS550 Run Better

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, particularly if you want to keep your 2014 Mercedes-Benz CLS550 in tip-top shape. Routine engine tune-ups can bring power back to your CLS550. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you’re taking vital steps toward keeping your CLS550’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz CLS550

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz CLS550 engine tune-up services. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your CLS550. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your CLS550's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your CLS550: 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.
