When should Mercedes-Benz GL550 spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What do I do if I see a pool of liquid under my Mercedes-Benz GL550?

What do hard starts and stops do to my GL550 engine?

The second service focuses on your GL550's filters, specifically replacing the air filter and fuel filter. Our third service is a thorough cleaning of the fuel system.

Restored fuel system performance. Keep in mind that your GL550's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours.
