NGK Audi A3 2010-2006 Direct Fit Oxygen Sensor

This is an NGK oxygen sensor, part number 25675. It's designed to directly replace the original sensor in a wide range of vehicles, including models like the Audi A3, Volkswagen GTI, and Porsche Cayenne. Oxygen sensors are a key part of your car's emissions control and engine management system. They constantly monitor the exhaust gases and send information back to the engine computer (ECU) to help maintain the right air-fuel mixture. This keeps your engine running efficiently, maximizes fuel economy, and helps reduce harmful emissions.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic sensor element. This element features a special coating that helps protect it from contaminants and deposits that can cause other sensors to fail prematurely. By controlling the ceramic element from the raw material stage, NGK ensures a well-built sensor that works reliably to alert your OBDII system to potential issues with fuel delivery or the catalytic converter.
