Walker Products Oxygen Sensor P/N:350-34354
Walker Products 350-64075 oxygen sensor for the 2006-2015 Mazda MX-5 4-cylinder 2.0L and other vehicles reads the oxygen in the exhaust gas. This sensor is a 4-wire wide-band air-fuel ratio sensor for the upstream position.
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean the sensor is failing. A damaged wiring harness or connector can also be behind them, so look both over for physical damage before replacing the sensor.
This sensor is a direct-fit replacement for the 2006-2015 Mazda MX-5 4-cylinder 2.0L and the 2006-2008 Mazda MX-5 Miata 4-cylinder 2.0L. Both take one sensor, and this listing is a single sensor.

Is this MX-5 oxygen sensor right for the 2006-2015 Mazda MX-5 4-cylinder 2.0L?
Yes. Walker Products 350-64075 is listed for the 2006-2015 Mazda MX-5 4-cylinder 2.0L, and it goes in the upstream position.
Is this Walker Products oxygen sensor a wide-band type?
Yes. Walker Products 350-64075 is a 4-wire wide-band air-fuel ratio sensor that determines the oxygen content of the exhaust gas.
Is this an upstream or downstream oxygen sensor?
Upstream. This sensor is listed for the upstream position.
Can a failing wide-band sensor make the engine run poorly or turn on a warning light?
Yes, a failed sensor can cause poor running, higher fuel use, higher exhaust emissions or a lit malfunction indicator light. A shop can read the stored fault codes.
What does the platinum layer on this oxygen sensor's electrodes do?
The electrodes are made of a gas-permeable platinum layer. Its coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates.
