Mercedes-Benz S420 Oxygen Sensor

Great cars and trucks like your S420 need great parts.

Select Your VehicleObviously, you didn't buy your S420 unless you understood you would be getting best-in-class service and a trusted brand both rolled up into one vehicle. While it may not be difficult to buy replacement parts for Mercedes-Benz vehicles, these days only the highest quality are required to fix your car or truck. Car aficionados know that a reliable name is built into each Mercedes-Benz, and know that only top quality replacement S420 parts will suffice when repairs are needed. You purchased your S420 because its performance and German engineering struck a chord inside you; so why would you be okay with anything but the best when it comes to the highest quality auto parts?

Don't go too long without fixing your Oxygen Sensor... here's why.

Achieving maximum power and fuel efficiency with your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Mercedes-Benz S420 is heavily controlled by a computer which relies on input from the oxygen sensors. Your Mercedes-Benz S420 oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.
