NGK Infiniti G20 2002 Direct Fit Oxygen Sensor

The advanced ceramic element in this NGK oxygen sensor features a 3-stage plasma jet and deposit trap overcoat. This design helps protect the sensor from poisoning by contaminants, which is crucial for maintaining optimal engine performance and fuel efficiency. As a key part of your vehicle's on-board diagnostic system, oxygen sensors constantly send feedback to the ECU to manage the air-fuel ratio. This helps reduce harmful emissions and alerts you to potential issues with fuel delivery or the catalytic converter.
