Front Oxygen Sensor for 2000-2002 Mazda 626 - Walker 350-34328

Walker Products 350-34328 front oxygen sensor for the 2000 Mazda 626 4-cylinder 2.0L and the 2000-2002 626 V6 2.5L measures how much oxygen is in the exhaust gas. That reading shows combustion efficiency and gives the ECU the diagnostic feedback it needs for this application.

• Monitors exhaust gases to help reduce pollutants
• Tracks the air fuel ratio for combustion efficiency
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
