Mercedes-Benz E420 Oxygen Sensor

Great cars and trucks like your E420 need great parts.

Mercedes-Benz automobile owners have come to expect a certain level of performance when driving their E420 around town. Your Mercedes-Benz dealership isn't the only place to buy genuine or original equipment quality parts to repair your E420. The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days. When your Mercedes-Benz E420 rolled off the assembly line, it was destined for a person with discerning taste who prioritizes German engineering in their automobile.

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 E420 is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Mercedes-Benz E420 oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and it will likely be emitting an excess of hazardous exhaust.

The best parts are right around the corner.
