    Walker Products 350-34447 oxygen sensor for the 1999-2000 Mazda Miata 4-cylinder 1.8L measures the oxygen in the exhaust gas to show combustion efficiency. Every Walker Products part number is made for its specific application and position, and returns the diagnostic feedback the ECU expects.

    • Electrodes with a gas-permeable platinum layer
    • Reads the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Oxygen readings help fine-tune the air-fuel mixture to support normal fuel economy
    • Monitors exhaust gases to help reduce pollutants

    Quick facts

    • Part: Walker Products 350-34447 oxygen sensor
    • Fits: the 1999-2000 Mazda Miata 4-cylinder 1.8L
    • Position: Downstream
    • Condition: New

    A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions 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.

    Fits

    This sensor fits the 1996-1997 and 1999-2000 Mazda Miata 4-cylinder 1.8L, and each of those cars takes one. The listing is a single sensor.

    Frequently Asked Questions

    Is this Miata oxygen sensor right for the 1999-2000 Mazda Miata 4-cylinder 1.8L?

    Yes. Walker Products 350-34447 is a downstream sensor for the 1999-2000 Mazda Miata 4-cylinder 1.8L, and it also fits the 1996-1997 Mazda Miata 4-cylinder 1.8L.

    What thread size does the Walker Products 350-34447 oxygen sensor have?

    The thread is M18 - 1.5. Walker Products 350-34447 is a 4-wire, direct-fit, narrow-band oxygen sensor.

    What happens when a downstream oxygen sensor starts to fail?

    The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator light can come on. Damage to the sensor, wiring harness or connector can be spotted by eye with the engine off.

    What does the coating on this oxygen sensor protect against?

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

    Is this narrow-band sensor an upstream or downstream unit?

    It is a downstream sensor. This listing is one sensor, and the fitment calls for one per car.
