Oxygen Sensor for 2012-2016 BMW 328i & More - Walker 250-241027

Walker Products 250-241027 oxygen sensor for the 2012-2016 BMW 328i 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas so combustion efficiency can be monitored. This Walker Products oxygen sensor is a downstream narrow-band unit that sends the ECU the diagnostic feedback it expects.

• Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
• Monitors exhaust gases to help reduce pollutants
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Electrodes made with a gas-permeable platinum layer
• Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
