Bosch Oxygen Sensor P/N:16643
Bosch 16790 rear oxygen sensor for the 2008-2010 BMW 535i 6-cylinder 3.0L and other vehicles reads exhaust oxygen and sends air-fuel-ratio data to the ECU. Its switching-type, narrow-band heated design helps the ECU keep combustion stable and emissions down.
A check engine light, a rough idle or lower fuel economy can be signs of a worn sensor. A vacuum leak, an exhaust leak or a misfire can sit behind those signs too, so track down the cause before you buy a replacement.
This listing is one oxygen sensor for the 2008-2010 BMW 535i 6-cylinder 3.0L, the 2009-2010 BMW 535i xDrive 6-cylinder 3.0L and the 2008 BMW 535xi 6-cylinder 3.0L. The quantity is one per car in this position.
