NTK is the world's largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle's on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology. NTK is constantly improving sensor designs to provide excellent performance and improve resistance to failure. NTK works with their OEM manufacturers through each phase of development from concept to production.

The NGK Part 24663 wideband oxygen sensor is engineered to optimize engine performance and reduce emissions on select Subaru and Toyota models, including the 2005-2009 Subaru Outback and 2008-2009 Subaru Legacy, as well as the 2013-2009 Toyota Highlander. This OEM-quality sensor provides a linear output signal, enabling the vehicle's ECU to precisely monitor and adjust the air-fuel mixture for optimal combustion. Accurate air-fuel ratio control results in better fuel efficiency, lower emissions, and improved engine responsiveness. The sensor's design incorporates advanced ceramic technology, ensuring durability and resistance to failure through continuous development and rigorous testing by NTK, the world's largest OEM oxygen sensor supplier. Installation is straightforward, offering a direct fit that aligns with factory specifications, making it suitable for both professional mechanics and experienced DIY enthusiasts. Proper functioning of this sensor is crucial for maintaining vehicle emissions compliance and engine health, especially in modern vehicles with sophisticated engine management systems. Be sure to acknowledge Prop 65 requirements when installing or handling this component, and verify compatibility before replacing your existing sensor.
