Walker Products 350-35002 rear oxygen sensor for the 2009-2016 BMW Z4 6-cylinder 3.0L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a wide-band unit that gauges combustion efficiency.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel ratio and support fuel economy
- Electrodes made of a gas-permeable platinum layer
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and mounting position, returning the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-35002 oxygen sensor
- Fits: 2009-2016 BMW Z4 6-cylinder 3.0L and other vehicles
- Position: Upstream, upstream rear
- Condition: New
Rough running, higher fuel use or a lit malfunction indicator light can mean the sensor is failing, but a damaged wiring harness or connector can be behind them too. With the engine cool, inspect the sensor, harness and connector for physical damage before replacing anything.
Fits

Frequently Asked Questions
Is this the right BMW Z4 oxygen sensor for a 2009-2016 model with the 6-cylinder 3.0L?
Yes. Walker Products 350-35002 fits the 2009-2016 BMW Z4 6-cylinder 3.0L as the upstream rear sensor, and the car takes one. Other BMW models are in the "Vehicles it fits" section.
What type of oxygen sensor is the Walker Products 350-35002?
The Walker Products 350-35002 is a wide-band oxygen sensor with electrodes made of a gas-permeable platinum layer and an M18 - 1.5 thread.
What can a failing oxygen sensor cause?
The engine can run poorly, exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles store fault codes, and a shop can read them to see which sensor is involved.
Does Walker Products 350-35002 interchange with CTK-OSKI5001?
Yes. CTK-OSKI5001 is listed as an interchange number for Walker Products 350-35002.
What does the coating on this oxygen sensor's electrodes do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
