the air temperature sensor is in the airbox - is this the one you are looking for ?
Normally it is the engine temp sensor which causes issues on these bikes - this is the sensor that screws into the head between #1 and #2 inlets.....
You will probably need to track down a complete airbox for any of the fuel-injected 1100's - B1, B2 or A1-A4. They all use the same style of air-temp sensor and the harness plug is the same for all these models. If you get lucky with an airbox, just make sure it has the air-temp sensor still fitted. Normally these small bits don't get removed from the airbox when they pull a bike apart to wreck.....
The Bosch stuff that is interchangeable, are things like fuel pumps, injector nozzles and O-rings etc.
