Oxygen Sensor for 1999-2003 Mazda Protege - Walker 350-34132

Walker Products 350-34132 oxygen sensor for the 1999-2003 Mazda Protege 4-cylinder 1.6L measures the oxygen content of the exhaust gas. It is a 4-wire, narrow-band sensor for the downstream position and monitors the air-fuel ratio for combustion efficiency.

• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
