NGK Audi TT Quattro 2001-2000 Direct Fit Oxygen Sensor

The ceramic element in this NGK oxygen sensor is made using advanced technology, starting from raw material all the way to the finished product. As a key part of your vehicle's on-board diagnostic system, oxygen sensors are crucial for keeping your engine running at its best. They provide constant feedback to the ECU, helping to control the air-fuel ratio, which in turn maximizes fuel efficiency and reduces harmful emissions.

This sensor features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the ceramic element from poisoning, ensuring consistent performance and alerting your OBDII system to potential issues with fuel delivery or the catalytic converter. NTK, a leading manufacturer of OEM oxygen sensors, works closely with vehicle manufacturers through every stage of development to ensure excellent performance and resistance to failure.
