Title: Bosch Car Oxygen Sensor (Lambda Sensor) replacement for K 1100
Post by: ffbikersa on May 08, 2018, 04:30:53 AM
Hello to everybody!

[/size]I had to replace the Oxygen Sensor (Lambda Sensor) on my 1993 K 1100 RS with the "regulated" catalytic converter. The original BMW's costs like hell  - so my buddy, a BMW "guru" from Croatia, advised me to use this one foreseen for cars as a much more affordable substitution:[/color]

I took the number provided by ffbikersa and mapped that to Bosch 15727 Oxygen Sensor, Universal Fitment.  I bought one on Amazon for $35.  The original connector needs to be spliced on.

My K1100 starts quicker and idles smooth.  It used to hunt and skip.

Yes most of the narrowband Bosch sensors are the same.  Either three wire wire or four wire (heater).  Only difference vehicle to vehicle is the connector.
