    Premium Wideband Air-Fuel Oxygen (O2) Sensors (0258017025) 1pce

    Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).

    These Wideband sensors use a more sophisticated sensing element that provides a signal to the vehicle’s ECU that is proportional to the amount of oxygen in the exhaust.

    This sensor can be used as stock replacement for defective or old sensors, and is compatible with the Wideband display AEM 30-4110 UEGO, and others.
