    Walker Products 250-24860 oxygen sensor for the 2009-2011 Mazda RX-8 1.3L measures the oxygen in the exhaust gas to show combustion efficiency. It is made for its specific fitment position and gives the ECU the diagnostic feedback it requires.

    • Monitors exhaust gases to help reduce pollutants
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Electrodes made of a gas-permeable platinum layer
    • Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy

    Quick facts

    • Part: Walker Products 250-24860 oxygen sensor
    • Fits: 2009-2011 Mazda RX-8 1.3L
    • Position: Downstream
    • Condition: New

    A worn sensor can show up as an engine that runs poorly, higher fuel use, more exhaust emissions or a lit malfunction indicator light. The sensor's wiring harness or connector may be behind those signs instead, so inspect both for physical damage before replacing the sensor.

    Fits

    It is a direct-fit downstream oxygen sensor for the 2009-2011 Mazda RX-8 1.3L. This listing is one sensor, and the car takes one.

    Frequently Asked Questions

    Does the Walker Products 250-24860 oxygen sensor fit the 2009-2011 Mazda RX-8 1.3L?

    Yes. Walker Products 250-24860 is a downstream oxygen sensor for the 2009-2011 Mazda RX-8 1.3L, and that application takes one sensor.

    Is this a narrow-band or a wideband oxygen sensor?

    The Walker Products 250-24860 is a narrow-band sensor with 4 wires and an M18 - 1.5 thread. It is a downstream sensor.

    What is the coating on this oxygen sensor for?

    The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces. The electrodes are made of a gas-permeable platinum layer.

    Could a rough-running engine point to a bad downstream oxygen sensor?

    A failed sensor can be one cause of rough running, higher fuel use or a lit warning light. A shop can read the stored fault codes to narrow it down.

    Does this downstream oxygen sensor monitor the air-fuel ratio?

    Yes. It determines the oxygen content of the exhaust gas, which lets the air-fuel ratio be monitored for combustion efficiency.
