Walker Products Oxygen Sensor P/N:350-64028
Walker Products 350-34470 oxygen sensor for the 2008-2010 Mazda 5 4-cylinder 2.3L measures the oxygen content of the exhaust gas on the downstream side. It is made for its specific application and fitment position, and it supplies the diagnostic feedback the ECU needs.
A failing sensor can show up as poor running, higher fuel consumption or a lit malfunction indicator light. Those signs can have other causes, so with the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace anything.
This oxygen sensor is a direct-fit replacement for the 2008-2010 Mazda 5 4-cylinder 2.3L.

This part cross-references / interchanges with the following part numbers:
Does the Walker Products 350-34470 fit the 2008-2010 Mazda 5 4-cylinder 2.3L?
Yes. Walker Products 350-34470 is a downstream, direct-fit oxygen sensor for the 2008-2010 Mazda 5 4-cylinder 2.3L.
Is this downstream oxygen sensor narrow-band or wideband?
It is a narrow-band sensor with 4 wires and an M18 - 1.5 thread.
Will a failing oxygen sensor set a fault code?
It can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them and test the sensor.
What does the coating on the Walker Products 350-34470 protect?
On the Walker Products 350-34470, the coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are a gas-permeable platinum layer.
Does Walker Products 350-34470 replace CTK-OSMA4010?
Yes. CTK-OSMA4010 is listed as an interchange number for Walker Products 350-34470, this downstream oxygen sensor.
