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 Part 25702 Wideband Oxygen Sensor is designed specifically for Jaguar models including the XJR, XJ8, and Vanden Plas from 1999 to 2003. This sensor plays a crucial role in your vehicle's onboard diagnostic system by providing precise measurements of the air-fuel mixture, which helps optimize engine performance, improve fuel efficiency, and minimize emissions. Featuring advanced ceramic technology, this sensor uses a three-stage contaminant-resistant plasma jet and deposit trap overcoat to protect against element poisoning, ensuring long-lasting reliability and consistent accuracy.

Designed with high-quality materials and state-of-the-art manufacturing processes, the NGK Vanden Plas 2003-1999 sensor offers a linear output signal that allows the ECU to make continuous, precise adjustments to the air-fuel ratio. This leads to improved combustion efficiency and reduced harmful emissions, making it a valuable replacement part for maintaining your vehicle's optimal operation. The sensor is a direct fit for select Jaguar models, ensuring seamless installation and compatibility without the need for extensive modifications.

As part of NGK's commitment to quality and innovation, this wideband oxygen sensor is engineered to resist contamination and failure, providing reliable performance over time. It is manufactured under strict quality controls to meet or exceed OE standards and is supported by full-market application technology. Trust the NGK Part 25702 to deliver consistent, accurate readings and help your vehicle operate at peak efficiency while adhering to environmental standards.
