The Walker Products Oxygen Sensor (part number 250-24135) is a direct-fit replacement for 1994-2001 Porsche, Saab, and Volvo vehicles with 3.6L, 3.4L, and 2.3L engines. The oxygen sensor measures combustion efficiency based off the amount of oxygen in the exhaust gas.
Features:
- Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
- 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.
- Monitors exhaust gases and reduces pollutants for a cleaner environment.
- Determines the oxygen content of the exhaust gas, monitoring the air fuel ratio for combustion efficiency.
