Oxygen Sensor for 2007-2013 BMW 328i & More - Walker 350-34621

Walker Products 350-34621 oxygen sensor for the 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit.

• Monitors exhaust gases and helps reduce pollutants
• Measures oxygen levels so the air-fuel mixture can be fine-tuned to support fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes coated with a gas-permeable platinum layer
• Diagnostic system feedback for the ECU, matched to the sensor's fitment position

A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, since a vacuum leak can produce some of them too. If the sensor is the cause, this part replaces it. Each sensor position takes one sensor, and this listing is a single sensor.

Fits

The 2007-2013 BMW 328i 6-cylinder 3.0L, the 2008-2010 BMW X6 6-cylinder 3.0L and the 2008-2019 X6 V8 4.4L, and the 2013-2019 BMW 650i Gran Coupe V8 4.4L are among the vehicles this sensor fits.
