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.

ADVANCED CERAMIC SENSOR ELEMENT: 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects against element poisoning

The NGK Toyota RAV4 2000-1998 Wideband Oxygen Sensor (Part #25697) is a high-precision component designed to optimize your vehicle's engine performance and emissions.
