intake air temperature sensor on e36 316 coupe?

You two are talking about two different sensors, the one with the hoses on the airbox is the intake air temperature sensor, and the one in the brake duct is the ambient temperature sensor. The one in the airbox is used in conjunction with the mass air and oxygen sensor readings to determine the fuel mixture, the ambient sensor is just used for the OBC display.

On my 320i (E36 touring) it's behind the front passenger side (UK) brake air duct (front bumper)
