Select Your VehicleObviously, you bought your Marquis because you knew that you wanted performance and American style both impeccably combined into one automobile. Your Mercury dealership isn't the only place to find trusted parts to repair your Marquis. Mercury car, truck, or SUV drivers have grown accustomed to a certain level of reliability when driving their Marquis around town. It's not a regular occurrence that you realize that you have to buy a replacement Catalytic Converter for your vehicle.

Why Catalytic Converter replacement is so important.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your Mercury Marquis 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 Mercury Marquis 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.

There's no reason to delay... checkout is simple and easy.
