Thats a drain pipe, mosture builds up inside the airbox and runs down into that pipe. You need to take the bung of the end from time to time to let the water out, youll probably find theres quite a bit in there, little bit of oil too youll probably find.

thank mate for the explanation so to make it short i can fasten it where i want most important is it will be facing downwards
to do its job

generally it goes down by the water pump, but its not accessible there, so leave mine hanging in front of the sprocket cover so i can empty it when i want to. I reckon its worse during the winter due to to the heat difference of the air coming in and the temperature of the airbox plastic, hence condensation.
