About Oxygen Sensor
One of the most important sensors in your vehicle is an oxygen sensor. By measuring concentration of oxygen in the system, it helps the ECU fine tune the air-fuel mixture and lets your vehicle perform to its full potential. However, the oxygen sensor is most often overlooked. We don't even know that it is damaged until the car fails the emissions test. And Autoxygensensor.com offers you replacement oxygen sensors that are identical to the OE parts but cost much less.
