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 Acura EL 2005-2004 Wideband A/F Sensor (Part Number 24664) is a high-performance oxygen sensor designed for optimal engine management. This sensor plays a critical role in the vehicle's on-board diagnostic system by providing a linear output signal that allows the ECU to precisely measure how rich or lean the engine runs. This capability enables continuous adjustments to the air-fuel mixture, helping to achieve the most efficient combustion, reduce emissions, and improve fuel economy.
Built with advanced ceramic sensor elements, the NGK sensor features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat, which protects against element poisoning and extends the sensor's lifespan. As a direct fit for select Honda and Subaru models, including the 2003-2005 Honda Civic and 2003-2004 Subaru Impreza and Baja, this sensor ensures reliable performance and easy installation. The sensor's robust construction is designed to withstand harsh engine conditions, providing consistent and accurate readings over time.
The NGK Wideband A/F sensor is suitable for use in vehicles requiring precise air-fuel ratio monitoring to meet stringent emissions standards. This product aligns with industry standards and features a ceramic element that is carefully controlled from raw material to finished product, ensuring high quality and durability. Whether for routine maintenance or performance upgrades, the NGK Acura EL sensor offers dependable operation and helps maintain your vehicle’s optimal performance and emissions compliance.
