Improve the accuracy and efficiency of your Audi’s engine with this Oxygen Sensor Lambda O2 designed for Audi A3, A4, A6, TT, Q5, and Q7 applications. This wide-band, heated oxygen sensor (LSU 4.9) delivers precise lambda readings across a broad range, helping your engine optimize fuel delivery, reduce emissions, and maintain smooth idle and responsive acceleration. Replacing worn or failing O2 sensors can recover lost fuel economy, restore performance, and keep your vehicle within strict emissions standards. With compatibility spanning multiple OEM references (including 0258017025, 17025, 0258017209, 30-2004 and 258017025), this sensor is a robust, ready-to-install solution for your Audi’s exhaust system. Built to endure the heat and harsh conditions of the exhaust stream, it supports reliable long-term operation and helps your ECU calibrate the air–fuel ratio accurately from cold start through cruising speeds.

Benefits & Tips

  • Enhances fuel efficiency by providing precise, real-time oxygen measurements that enable optimal fuel mixture updates.
  • Reduces exhaust emissions and helps your vehicle pass stringent emissions tests by maintaining the correct air–fuel ratio.
  • Faster warm-up and stable engine performance thanks to its heated (heating) sensor design, which minimizes cold-start drivability issues.
