Front Oxygen Sensor for 2003-2008 Mazda 6 - Walker 250-24474

Walker Products 250-24474 front oxygen sensor for the 2003-2008 Mazda 6 V6 3.0L measures the oxygen content of the exhaust gas. The engine computer uses that reading to monitor the air-fuel ratio for combustion efficiency.

• Monitors exhaust gases to help reduce pollutants
• Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel ratio can be fine-tuned for fuel economy
• Sends the ECU the diagnostic feedback it requires for this sensor position
