NTK is the world's leading supplier of OEM oxygen sensors. NTK oxygen sensors are individually tested to ensure the highest level of quality and reliability. NTK oxygen sensors continuously detect the composition of exhaust gases. As the output from the sensors changes, the ECU instructs the fuel mixing system to alter the mixture. This ensures that the air/fuel mixture is always correct and promotes efficiency. A new NTK oxygen sensor can help lower emissions, improve fuel mileage and 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 OE specifications and are equipped with waterproof, factory-fitted connectors to ensure a perfect fit every time. Rely on the world leader in sensor technology--NTK.
