Walker Products 350-34263 oxygen sensor for the 1996-1999 Nissan Maxima V6 3.0L and other vehicles measures the oxygen in the exhaust so the engine computer can judge combustion efficiency. This direct-fit, narrow-band sensor has 4 wires and sits in the downstream position.

• Determines the oxygen content of the exhaust gas to monitor 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
• Monitors exhaust gases to help reduce pollutants
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
