NGK Audi A3 2013-2010 Direct Fit 5-Wire Wideband A/F Sensor

This NGK 5-wire wideband air-fuel ratio (A/F) sensor uses an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor from poisoning, ensuring it can accurately measure the air-fuel mixture. Unlike standard oxygen sensors that just signal rich or lean, this wideband sensor provides a linear output. This allows your vehicle's computer (ECU) to precisely adjust the air-fuel ratio for optimal combustion, better fuel efficiency, and reduced emissions.

As the world's largest supplier of OEM oxygen sensors, NTK builds these sensors with state-of-the-art technology, controlling the ceramic material from start to finish. This direct-fit sensor is designed to replace the original on a wide range of Audi and Volkswagen vehicles, including models like the Audi A3, Audi A4, and Volkswagen Jetta. Trust NGK, the sensor specialists, for OE application technology that helps maintain optimal engine performance.
