Walker Products 350-34418 left oxygen sensor for the 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles reads the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit that monitors the air-fuel ratio for combustion efficiency.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34418 oxygen sensor
- Fits: 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles
- Position: Downstream left
- Condition: New
A damaged wiring harness or connector can be behind the signs of a failing sensor too: a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Look both over for physical damage and find the cause before buying a sensor.
Fits

Frequently Asked Questions
Does this Mercedes C280 oxygen sensor fit the 1998-2000 Mercedes-Benz C280 V6 2.8L?
Yes. Walker Products 350-34418 fits the 1998-2000 Mercedes-Benz C280 V6 2.8L at the downstream left position. For another car, enter its year and engine in the "Vehicles it fits" section.
Is Walker Products 350-34418 a single sensor for the downstream left position?
Yes. This listing is one oxygen sensor for the downstream left position, and the other sensor positions are separate parts.
Is the Walker Products oxygen sensor narrow-band or wideband?
Narrow-band. This is a 4-wire, direct-fit narrow-band oxygen sensor.
What signs can point to a failed downstream left oxygen sensor?
Signs can include a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Newer vehicles store fault codes in the ECU, and a shop can read them.
What does the coating on the electrodes of this oxygen sensor do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
