Walker Products Oxygen Sensor P/N:250-241273
Walker Products 250-24857 oxygen sensor for the 2009-2015 Mercedes-Benz G550 V8 5.5L measures combustion efficiency from the amount of oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire narrow-band unit made for its specific application and fitment position.
A failing sensor can show up as poor running, higher fuel consumption or a lit malfunction indicator light. A damaged wire or connector can trigger these signs as well, so with the engine off and cool, look over the sensor, its wiring harness and its connector for physical damage before you order. A shop can test the rest.
This sensor is a direct-fit replacement for the 2009-2015 Mercedes-Benz G550 V8 5.5L. This listing is one sensor, and that vehicle takes one.

Does the Walker Products 250-24857 oxygen sensor fit the 2009-2015 Mercedes-Benz G550 V8 5.5L?
Yes. Walker Products 250-24857 is listed for the 2009-2015 Mercedes-Benz G550 V8 5.5L in the downstream left and downstream right positions.
Is this a narrow-band or a wideband oxygen sensor?
It is narrow-band. Walker Products 250-24857 is a 4-wire narrow-band sensor with an M18 - 1.5 thread.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
How can I tell if this downstream oxygen sensor is going bad?
Poor running, higher fuel consumption or a malfunction indicator light can point to a failing sensor, though other faults cause them too. A shop can read the stored fault codes.
Is this downstream oxygen sensor made for one specific application?
Yes. Each Walker Products part number is made for its own application and fitment position, and this sensor gives the ECU the diagnostic feedback that application needs.
