Oxygen Sensor Basics

NTK is the world’s leading supplier of OEM oxygen sensors, supplying more vehicle makers with oxygen sensors than any other manufacturer. NTK oxygen sensors are individually tested to ensure the highest level of quality and reliability.

Everyone agrees the amount of pollution produced by motor vehicles should be reduced. In order to reduce emissions, governments have progressively introduced stricter emission legislation. Since 1981, many cars and light trucks built throughout the world have been equipped with oxygen sensors.

NTK oxygen sensors detect the level of oxygen in the exhaust gases. As the output from the O2 sensor changes, the ECU controls the fuel delivery system to adjust the air-fuel mixture. This ensures that the air-fuel mixture is always correct for best engine and catalyst performance.

A new NTK oxygen sensor can help lower emissions, improve fuel mileage, improve engine efficiency and extend catalyst life.

NTK oxygen sensors are OEM-approved and are built with the highest quality materials and craftsmanship to ensure superior quality for your automobile. NTK oxygen sensors meet or exceed original equipment specifications and are equipped with waterproof factory-fitted connectors to ensure a perfect fit every time.
