The Firestone Complete Auto Care location in your community offers several Mercedes-Benz S420 engine tune-up services. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your S420. 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 S420's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your S420's mileage and maintenance history can uniquely impact its tune-up needs.
