Walker Products 250-24605 oxygen sensor for the 1992-1995 BMW 325i 6-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire, direct-fit narrow-band unit that sends the ECU its oxygen reading.
- Monitors exhaust gases and reduces pollutants
- Electrodes have a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas to track the air-fuel ratio
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24605 oxygen sensor
- Fits: 1992-1995 BMW 325i 6-cylinder 2.5L and other vehicles
- Position: Upstream, upstream left, upstream right

A failing sensor can show up as poor engine running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, rule out damage to its wiring harness and connector, and have any stored ECU fault codes read, because harness damage can also shorten a sensor's life.

Frequently Asked Questions
Is this BMW M3 oxygen sensor right for the 1995 model year with the 6-cylinder 3.0L?
Yes. Walker Products 250-24605 is listed for the 1995 BMW M3 6-cylinder 3.0L with a quantity of one. For other BMW models, open the "Vehicles it fits" section.
Is the Walker 250-24605 a narrow-band or wideband sensor?
Walker Products 250-24605 is a narrow-band, 4-wire direct-fit sensor with an M18 - 1.5 thread.
What does the coating on this oxygen sensor protect against?
The coating keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces. The electrodes have a gas-permeable platinum layer.
Is the 250-24605 an upstream oxygen sensor?
Yes. The position is listed as upstream, upstream left and upstream right. This listing is one sensor.
Does the 250-24605 send diagnostic feedback to the ECU?
Yes. This sensor is made for its specific application and fitment position, and it provides the diagnostic feedback the ECU requires.
