If your check engine light is on, or you're noticing a drop in fuel economy, it might be time to replace your oxygen sensor. This direct-fit oxygen sensor from NGK is designed to work with a wide range of vehicles, including popular models like the Infiniti G20, Nissan Frontier, and Mercury Villager. A properly functioning oxygen sensor is crucial for your vehicle's on-board diagnostic system, helping to control the air-fuel ratio for optimal engine performance, better fuel efficiency, and reduced emissions.

NGK, a leading manufacturer of OEM oxygen sensors, uses advanced ceramic sensor elements in this part. This design features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat, which helps protect the sensor from poisoning and ensures consistent feedback to your vehicle's ECU. This advanced construction helps maintain optimal engine performance and alerts your OBDII system to potential issues with fuel delivery or the catalytic converter.
