Walker Products Oxygen Sensor 250-54058 - 4-Wire Wide-Band

The Walker Products Oxygen Sensor (part number 250-54058) is a direct-fit replacement part. The oxygen sensor measures combustion efficiency based off the amount of oxygen in the exhaust gas.

Features:

• Monitors exhaust gases and reduces pollutants for a cleaner environment.
• Coated in with electrodes made of a gas-permeable platinum layer.
• Measures oxygen levels to fine-tune air-fuel mixture, improving fuel economy and saving costs.
• Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
• Determines the oxygen content of the exhaust gas, monitoring the air fuel ratio for combustion efficiency.
