BMW Oxygen Sensor - O2 Sensors for BMW 7 Series F01 (2009+)

Clear BMW chassis
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.

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.

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.

This Bosch Lambda sensor is used with aftermarket engine management systems around the world. It's a universal racing oxygen sensor but only works with specialized racing engine management, advanced air/fuel and Lambda gauges, and Bosch Motorsport ECUs and Lambda control boxes (LT4). This is not a universal sensor to work in any production BMW. This is a motorsport-only wideband O2 sensor.

This sensor is designed to measure the oxygen content and Lambda value of exhaust gases in automotive gasoline engines. The wideband Lambda sensor LSU 4.9 is a planar ZrO2 dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of I>> = 0.65 to air makes the LSU capable of being used as a universal sensor for I>> = 1 measurement as well as for other Lambda ranges. The connector module contains a trimming resistor, which defines the characteristic of the sensor. The LSU4.9 operates only in combination with a special LSU-IC, used in most Bosch Motorsport ECUs and Lambda control boxes (LT4).

The main benefit of the LSU is the robust design combined with the high Bosch production quality standard.

Application Hints:

  • The Lambda sensor should be installed at a point which permits the measurement of a representative exhaust-gas mixture, which does not exceed the maximum permissible temperature.
  • As far as possible install the sensor vertically (cable upwards).
  • The sensor is not to be fitted near to the exhaust pipe outlet, so that the influence of the outside air can be ruled out.
  • The exhaust piping must be free of leaks in order to avoid the effects of leak-air.
  • Protect the sensor against condensation water.
  • The sensor is not to be coated or painted, nor is wax to be applied or any other forms of treatment.
  • Use only the recommended grease for lubricating the thread.

Application Data:

  • Exhaust Gas Pressure< 4bar
  • Exhaust Gas Temp Range (operating)< 930*C / 1,706*F
  • Exhaust Gas Temp Range (max)< 1,030*C / 1,886*F
  • Hexagon Temp< 600*C / 1,112*F
  • Cable and Protective Sleeve Temp< 250*C / 482*F
  • Connector Temp< 140*C / 284*F
  • Max Vibration (Stochastic Peak Level)< 1,000 m/s2

Mechanical Data:

  • Weight (without cable)120g
  • Length (without cable)84mm
  • Cable Length32.2cm
  • ThreadM18x1.5
  • Wrench Size22mm
  • Tightening Torque40...60Nm

Price is per sensor.
