Audi VW Oxygen Sensor NTK - 25621

Your oxygen sensor works with your car's computer to optimize your engine's performance. If it is not working properly the result could include reduced fuel mileage, failed emissions testing as well as a check engine light.

NTK is part of the NGK product family. Whereas NGK specializes in spark plugs, NTK specializes in O2 Sensors, also known as Oxygen Sensors. In fact NTK supplies more OEM oxygen sensors to automobile makers than any other manufacturer in the world. As an OEM, all NTK products are OEM certified and are designed with the highest quality materials, so all NTK oxygen sensors meet or surpass original equipment specifications. Also, all sensors now use waterproof factory fitted connectors so expect NTK sensors to fit perfectly the first time. Placing a new NTK oxygen sensor in your vehicle will help contribute to lower emissions, improved gas mileage, better engine performance, and extend the catalyst’s life.
