Mercedes-Benz S420 Spark Plug

Keeping your S420 in top shape is your top priority.

Select Your VehicleObviously, you bought your S420 because you knew that you wanted best-in-class service and a trusted brand both impeccably combined into one automobile. The vehicle in your driveway symbolizes the best in class compared to all the other vehicles on the road today. Mercedes-Benz car, truck, or SUV drivers have come to expect a certain level of a reputation for strength when driving their S420 around town. It's not every day that you realize that you have to buy a replacement Spark Plug to repair your vehicle.

The function and purpose of Spark Plug.

Some engine parts are tucked away out of sight, so they aren't considered when there's a performance problem. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Mercedes-Benz S420 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. When one of the spark plugs does not fire when it should, the engine in your Mercedes-Benz S420 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

Time has come... buy your replacements right now.
