Select Your VehicleAnyone who owns a Mercedes-Benz knows that when it comes to maintaining their car, truck, or SUV only the highest quality replacement parts will do. Auto enthusiasts know that luxury is built into each Mercedes-Benz, and know that only the highest quality replacement 420SEL parts will suffice when your car or truck needs fixing. Make no mistake, you didn't buy your 420SEL unless you wanted to buy best-in-class service and dependability both rolled up into one automobile. Mercedes-Benz car, truck, or SUV enthusiasts have become used to a certain level of performance when driving their 420SEL around town.

Why Oxygen Sensor replacement is so important.

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 420SEL is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Mercedes-Benz 420SEL 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.
