Bosch 16002 Downstream Oxygen O2 Sensor for Audi, Porsche, VW (2005–2018)

The Bosch 16002 Downstream Oxygen (O2) Sensor is engineered to meet or exceed OEM specifications for Audi, Porsche, and Volkswagen vehicles from 2005 to 2018. Positioned after the catalytic converter, the downstream oxygen sensor monitors exhaust gases to ensure emissions compliance and optimal catalytic converter efficiency. A failing downstream O₂ sensor can trigger check engine lights, reduce fuel economy, or cause emission test failures. This high-quality Bosch sensor restores accurate exhaust gas readings, supports proper fuel mixture, and maintains engine performance. It is built for long-lasting reliability and features a direct-fit, plug-and-play design for easy installation.
