Oxygen Sensor for 1992-1995 Lexus SC400 & More - Walker 350-34522

Walker Products 350-34522 oxygen sensor for the 1992-1995 Lexus SC400 V8 4.0L and other vehicles measures the oxygen content of the exhaust gas to track combustion efficiency. It is made for its specific application and fitment position.

• Determines exhaust oxygen content to monitor the air-fuel ratio for combustion efficiency
• Monitors exhaust gases to help reduce pollutants
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
• Sends the diagnostic feedback the ECU needs for its application
