Walker Products 250-23025 oxygen sensor for the 1983-1988 Porsche 944 4-cylinder 2.5L and other vehicles measures the oxygen content of the exhaust gas. This upstream sensor is made for its specific application and gives the ECU the diagnostic feedback it expects.

• Monitors the air-fuel ratio by reading oxygen in the exhaust, a measure of combustion efficiency
• Monitors exhaust gases to help reduce pollutants
• Electrodes coated with a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Oxygen readings let the air-fuel mixture be fine-tuned, which supports fuel economy
