    Walker Products 350-34265 center oxygen sensor for the 2005-2008 Mazda 6 4-cylinder 2.3L measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is made for its specific application and fitment position and gives the ECU the diagnostic feedback it expects.

    • Narrow-band sensor with four wires
    • Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
    • Monitors exhaust gases to help reduce pollutants
    • Electrodes with 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 350-34265 oxygen sensor
    • Fits: 2005-2008 Mazda 6 4-cylinder 2.3L

    Frequently Asked Questions

    Will this oxygen sensor replacement work on a 2005-2008 Mazda 6 4-cylinder 2.3L?

    Yes. Walker Products 350-34265 fits the 2005-2008 Mazda 6 4-cylinder 2.3L (L4-2.3L), and that engine takes one sensor.

    Is the Walker Products oxygen sensor 350-34265 a narrow-band type?

    Yes. Walker Products 350-34265 is a narrow-band sensor with four wires and an M18 - 1.5 thread size.

    What does the platinum layer on this oxygen sensor do?

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

    Can a lit malfunction indicator light mean this oxygen sensor has failed?

    Yes, it can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor; poor running or higher fuel use can go along with a failed sensor.

    Does this oxygen sensor help with fuel economy and emissions?

    It monitors exhaust gases and measures oxygen levels so the air-fuel mixture can be fine-tuned. That helps support fuel economy and reduce pollutants.
