BMW Oxygen Sensor - O2 Sensors

Every new BMW, and all BMW cars made from 1980 on, have an oxygen sensor, often called an "O2 sensor". The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to by simply changing your oxygen sensor today. We carry Bosch oxygen sensors, and in some cases Genuine BMW oxygen sensors or OEM oxygen sensors.

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary. Bosch Part # 13 231. Replacement for BMW part # 11781735499 and 11781738282.

Made in the USA O2 Sensor Bung and plug. This weld-in bung allows an O2 sensor to be screwed into your exhaust system. It's required for custom exhaust systems, and is also useful for air/fuel ratio measurements when dyno testing. A threaded plug is included to cap off when not in use. Bung and cap/plug are both 100% stainless steel. The bung and plug are also available separately (in case you don't need both). Simply choose your option below.

  4. Copper Crush Ring for leak free installation
Install Tips
  • Locate bung as close to engine a possible, without exceeding the maximum operating temperature for the O2 sensor. The suggested location is just down-stream of the merge-collector on each bank of cylinders.
  • Sensors located after upstream exhaust system leaks or too close to exhaust outlets are susceptible to poor readings or influence of ambient air
  • O2 Sensors exposed to exhaust gasses with too high amount of un-burnt fuel can lead to misleading readings. A possible lean reading.
  • Locate sensor/bung 90deg to exhaust gas stream.
  • Locate sensor/bung in tube with a minimum of 10deg up angel to prevent liquid build up in sensor element.
  • Use stainless steel welding wire or rod when installing bung.
  • Do not have bung plug or a oxygen sensor installed when welding bung in place.
  • Welding can distort the bung so it is recommended you chase/tap the threads of the bung after welding.
  • When installing O2 sensor or plug, use an O2 sensor compatible high temperature resistant grease on the threads.
  • Use tightening torque suggested by O2 senor manufacturer.

Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance.
