    Walker Products 350-34570 oxygen sensor for the 2006-2008 Mazda 6 4-cylinder 2.3L measures the oxygen in the exhaust gas to gauge combustion efficiency. It is a 4-wire, narrow-band downstream sensor.

    • Monitors the air fuel ratio from the exhaust gas oxygen content
    • Coating protects electrode surfaces from combustion residue and particulates in the exhaust gases
    • Oxygen readings help fine-tune the air-fuel mixture for fuel economy
    • Monitors exhaust gases to help keep pollutants down
    • Electrodes made with a gas-permeable platinum layer

    Quick facts

    • Part: Walker Products 350-34570 oxygen sensor
    • Fits: 2006-2008 Mazda 6 4-cylinder 2.3L
    • Position: Downstream
    • Condition: New

    A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, since a misfire can also make the engine run poorly.

    Fits

    This is a direct-fit oxygen sensor replacement for the 2006-2008 Mazda 6 4-cylinder 2.3L (L4-2.3L). This listing is one downstream sensor, and that engine takes one.

    Frequently Asked Questions

    Does the Walker Products 350-34570 fit a 2006-2008 Mazda 6 with the 2.3L engine?

    Yes. The Walker Products 350-34570 is a downstream oxygen sensor for the 2006-2008 Mazda 6 4-cylinder 2.3L (L4-2.3L), and that engine takes one.

    Is this Walker Products oxygen sensor narrow-band or wideband?

    This is a narrow-band sensor. The Walker Products 350-34570 has 4 wires and a gas-permeable platinum layer on its electrodes.

    What thread size does this downstream oxygen sensor have?

    The thread size is M18 - 1.5. The sensor mounts downstream and has 4 wires.

    Can a failing oxygen sensor store a fault code in the ECU?

    Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them to see which sensor is flagged.

    What else should be inspected along with a worn oxygen sensor?

    The sensor's wiring harness and connector should also be checked for physical damage, since damage there can shorten the sensor's operating life.
