    Walker Products 250-54031 oxygen sensor for the 2004-2008 Mazda RX-8 1.3L measures the oxygen in the exhaust gas to monitor the air-fuel ratio. It reads from the upstream position.

    • Determines the oxygen content of the exhaust gas to monitor combustion efficiency
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Electrodes made of a gas-permeable platinum layer
    • Monitors exhaust gases to help reduce pollutants
    • Made for its specific application and fitment position to give the ECU the diagnostic feedback it needs

    Quick facts

    • Part: Walker Products 250-54031 oxygen sensor
    • Fits: 2004-2008 Mazda RX-8 1.3L

    Frequently Asked Questions

    Is this oxygen sensor for the 2004-2008 Mazda RX-8 1.3L an upstream or downstream sensor?

    Upstream. Walker Products 250-54031 is an upstream oxygen sensor for the 2004-2008 Mazda RX-8 1.3L, and the car takes one.

    What is the platinum layer on this oxygen sensor's electrodes?

    The electrodes are made of a gas-permeable platinum layer. A coating also protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.

    Which signs can come from a worn upstream oxygen sensor?

    The engine can run poorly, fuel consumption can rise, or the malfunction indicator light can come on. A shop can read the stored fault codes to narrow down the cause.

    Is this oxygen sensor made for one specific application?

    Yes. Walker Products makes each part number for its specific application and fitment position, so 250-54031 gives the ECU the diagnostic feedback it requires.

    Is this upstream oxygen sensor sold as a single piece or a set?

    It is sold as a single sensor. The car takes one in the upstream position.
