Genuine Mercedes-Benz Spark Plugs

Mercedes-Benz engines can't burn fuel and oxygen for power without spark plugs to start the combustion process. Turn your key in its ignition lock cylinder, and you'll see the process in action: first, an ignition switch triggers; then, many other ignition parts -- your battery and starter motor, the starter solenoid, and an ignition coil -- work to send electricity to the plugs' leads; and when the "spark" reaches them, the air and gas in the engine ignite, releasing said power. The engine's pistons and crankshaft can then get moving, and the many other parts that drive the luxury car or SUV you love get going.

Without spark plugs, though, no Mercedes-Benz vehicle (or any vehicle, for that matter) could start at all, and even the best goes bad from use and age eventually. Signs that's happening or has happened include corroded or overly widened leads, conductivity problems, a misfiring engine, and complete engine failure. Broken spark plugs, however, are a worse scenario: they can cause severe damage to an engine's cylinders.

Luckily, those manufactured these days last as many as 100,000 miles, and for millions of ignitions --they'll just need to be replaced before reaching their mileage limits. The question then becomes "what spark plugs do I need?" That depends on your Mercedes-Benz model. Choose genuine OEM works best either way. The brand you love designs and builds them compatible with the model you drive specifically, after all, and that kind of fitment guarantee, you may not always get on the aftermarket.
