What is an Air Fuel Ratio (A/F) sensor and why is it important?

An A/F sensor, also known as a wideband oxygen sensor, measures the oxygen content in your exhaust. This data helps the engine computer precisely control the fuel-air mixture for optimal combustion, fuel economy, and reduced emissions.

How do I know if my A/F sensor needs to be replaced?

Common signs include a check engine light, decreased fuel economy, rough idling, or poor engine performance. A diagnostic scan can often pinpoint a faulty oxygen sensor.

Does this sensor come with the necessary hardware for installation?

This NGK A/F sensor is designed as a direct replacement and typically includes the sensor itself. It is recommended to consult your vehicle's service manual or the manufacturer's installation guide for any additional hardware or specific installation procedures.

Product Details

If your check engine light is on and you suspect an issue with your air-fuel mixture, replacing your oxygen sensor is a common fix. This NGK 4-wire air fuel ratio (A/F) sensor is built to match the original equipment specifications for your 2016-2024 Infiniti Q50, as well as select Nissan models.

An A/F sensor, sometimes called a wideband oxygen sensor, plays a vital role in your engine's performance and emissions. It measures the amount of oxygen in the exhaust gases and sends that data back to the engine control module (ECM). The ECM then adjusts the fuel injection to maintain the optimal air-fuel ratio for efficient combustion. When this sensor starts to wear out, it can lead to poor fuel economy, rough idling, and increased emissions. This NGK sensor is designed as a direct replacement, ensuring it fits right and functions like the original part.

This sensor is a well-built component from NGK, a trusted name in ignition and sensor technology. It's a solid option for restoring your vehicle's proper fuel metering and emissions control. Always refer to your vehicle's service manual for specific diagnostic procedures and installation instructions.
