Walker Products 350-34888 right oxygen sensor for the 2014-2021 BMW i3 2-cylinder 0.6L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor tracks the air-fuel ratio, and the ECU uses that feedback to judge combustion efficiency.
- Made for a specific application and fitment position to give the ECU the diagnostic feedback it needs
- Electrodes made of a gas-permeable platinum layer
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and exhaust particulates
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34888 oxygen sensor
- Fits: 2014-2021 BMW i3 2-cylinder 0.6L and other vehicles
- Position: Downstream right
- Condition: New
A failing oxygen sensor can show up as poor running, higher fuel consumption or a lit malfunction indicator light. Before you replace it, rule out a damaged wiring harness or connector, since other faults can produce these signs too. Look them over for physical damage with the engine off and the exhaust cool.
Fits
The vehicles it fits include the 2014-2021 BMW i3 2-cylinder 0.6L, the 2016-2021 BMW M2 6-cylinder 3.0L and the 2018-2021 BMW i3s 2-cylinder 0.6L, along with many other BMW models. If your car is not one of those, look it up in the "Vehicles it fits" section before you order.

Frequently Asked Questions
Does the Walker Products 350-34888 fit the 2016-2021 BMW M2 6-cylinder 3.0L?
Yes. The Walker Products 350-34888 right oxygen sensor fits the 2016-2021 BMW M2 6-cylinder 3.0L, and that car takes one sensor.
Is the 350-34888 sensor narrow-band or wideband?
The Walker Products 350-34888 is a narrow-band, 4-wire, direct-fit sensor. It is made for the downstream right position.
Does this listing come as one sensor or a pair?
This listing is one downstream right oxygen sensor. The fitment calls for a quantity of one per vehicle.
What can a worn downstream oxygen sensor cause?
It can show up as the engine running poorly, higher fuel consumption or more exhaust emissions. A shop can read the stored fault codes to see which sensor they relate to.
What is the coating on the electrodes for?
The coating keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces. The electrodes themselves are made of a gas-permeable platinum layer.
