Oxygen Sensor 11781742050,18301407994,SU5732,11787513962 for BMW

Advantages of Zirconia Oxygen Sensor
Zirconium dioxide sensors can be directly inserted into high-temperature exhaust gas.
Directly inserted, help output compatible and stable.
Because they are integrated electronic circuit products, they can be directly connected to the ECU.
Based on their electronic communication functions, they are most suitable for vehicle automatic diagnosis systems (OBD).
Observing the color of the top part of the oxygen sensor to determine fault :
1.Light grey tip: This is the normal color of the oxygen sensor;
2.White tip: Caused by silicon pollution, it is time need to replace the oxygen sensor;
3.Brown tip: Caused by lead pollution, if serious, the oxygen sensor must also be replaced;
4.Black tip: Caused by carbon deposits, after eliminating the engine carbon deposit fault, the carbon deposits on the oxygen sensor can generally be automatically removed.
