Mercedes-Benz E420 drivers may realize their car has an oxygen sensor installed in the exhaust system as part of emissions control, but how many realize that this particular model vehicle is equipped with four separate O2 sensors? Each of these must be functioning properly in order for your car to realize maximum performance, as the O2 sensor is an essential element in the regulation of the air/fuel mixture being injected into the engine cylinders. Parks Geek stocks a complete line of oxygen sensors for the Mercedes E420, including OEM parts manufactured by Bosch. Buyers need to be certain to obtain the correct sensor, noting if the part is for the left side or right, upstream or down. The E420 was only made for three model years: 1994, 1995 and 1997 (no 1996s were manufactured), and it's also important to get a replacement sensor designed to fit your exact year.


They are available for the following Mercedes E420 years: 1997, 1995, 1994, 97, 95, 94. This part is also sometimes called Mercedes E420 O2 Sensor. We stock oxygen sensor parts for most Mercedes models including E320, C230, ML320, C280, CLK320, 300E, S500, CLK430, ML430, SL500, SLK230, C240, S320, E430, S430, 190E, C220, SLK320, S420, ML350, 420SEL, S600, C320, 560SEL, 380SL, E350, SL320, E55 AMG, ML500, 300SE, 500SL, 300CE, C63 AMG, C43 AMG, C300, 260E, 560SL, ML55 AMG, 300SEL and 560SEC.

We stock these Oxygen Sensor brands for the Mercedes E420: Bosch, Walker Products, Denso and Walker.
