Walker Products 350-35079 right oxygen sensor for the 2014-2021 BMW i3 2-cylinder 0.6L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. The ECU uses that reading to fine-tune the air-fuel mixture.
A failing oxygen sensor can show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace it, rule out physical damage to the sensor's wiring harness and connector, which can also shorten a sensor's life.
The vehicles it fits include the 2016-2021 BMW M2 6-cylinder 3.0L and the 2018-2021 BMW i3s 2-cylinder 0.6L, with a quantity of one per application. This listing is one sensor for the right upstream position. If your car is not named here, look up its year and engine on the Buyer's Guide tab.
Fit and size
Build and materials
Does this Walker Products oxygen sensor fit the 2016-2021 BMW M2 6-cylinder 3.0L?
Yes, Walker Products 350-35079 fits the 2016-2021 BMW M2 6-cylinder 3.0L, which takes one. It also fits the 2014-2021 BMW i3 2-cylinder 0.6L.
Is the Walker Products 350-35079 an upstream or downstream sensor?
The catalog lists it as an upstream sensor for the right position. This listing is one sensor, and each application takes one.
What thread size does this wide-band oxygen sensor have?
The thread size is M18 - 1.5. This sensor is a 5-W wide-band type.
What signs can point to a worn wide-band oxygen sensor?
The engine may run poorly, fuel consumption or exhaust emissions may rise, or the malfunction indicator light may come on. A shop can read the stored fault codes to see whether the sensor is involved.
What does the coating on the electrodes of this oxygen sensor do?
On the Walker Products 350-35079, the coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
