Walker Products 350-34349 oxygen sensor for the 2008-2014 Mercedes-Benz CL65 AMG V12 6.0L and other vehicles measures oxygen in the exhaust gas. It is a direct-fit narrow-band sensor made for a specific application and position, and it gives the ECU the diagnostic feedback it expects.
- Exhaust gas monitoring helps reduce pollutants
- Oxygen content readings let the sensor monitor the air-fuel ratio for combustion efficiency
- Oxygen level measurement helps fine-tune the air-fuel ratio and supports fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34349 oxygen sensor
- Fits: 2008-2014 Mercedes-Benz CL65 AMG V12 6.0L and other vehicles

Frequently Asked Questions
Is the Walker Products 350-34349 right for a 2008-2014 Mercedes-Benz CL65 AMG V12 6.0L?
Yes. Walker Products 350-34349 is listed for the 2008-2014 Mercedes-Benz CL65 AMG V12 6.0L. The 2008-2013 cars take one sensor and the 2014 model takes two.
Does the Walker Products 350-34349 oxygen sensor fit the 2003-2014 Mercedes-Benz CL600 V12 5.5L?
Yes. Walker Products 350-34349 is listed for the 2003-2014 Mercedes-Benz CL600 V12 5.5L. For other vehicles, find your year and engine in the "Vehicles it fits" section.
What thread size does this narrow-band oxygen sensor have?
It has an M18 - 1.5 thread and a threaded mount. It is a 4-wire narrow-band sensor.
How can I tell if this oxygen sensor is going bad?
A failing sensor can cause rough running, higher fuel consumption or a warning light. With the engine off and cool, you can look over the wiring harness and connector for physical damage.
What protects the electrodes on this Walker oxygen sensor?
A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
