Your S420 is a prized possession.

Select Your VehicleMercedes-Benz automobile enthusiasts have grown accustomed to a certain level of a reputation for strength when driving their S420 around town. The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs currently being driven today. Car aficionados know that a reliable name is built into each Mercedes-Benz, and understand that only top quality replacement S420 parts will suffice when your car or truck needs fixing. Anyone who operates a Mercedes-Benz knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do.

The function and purpose of Catalytic Converter.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your Mercedes-Benz S420 catalytic converter is the result of about a decade of engineering that took place in the 1960s and 70s. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that turn the carbon monoxide and hydrocarbons that your Mercedes-Benz S420 produces into harmless molecules of carbon dioxide, oxygen, and some water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.

You've tried the rest, now try the best.
