air filter



  BMW M135I
im looking to put the standard filter back onto the 172 because the last person changed it to a crap type r 1 that annoying and rattly, now theres 3 holes and im wondering what goes where, the top one goes to the engine, the bottom closest one to the bumper to the best cold air feed and what about the one at the back?

correct me if im wrong anywhere

or a diagram/pic would be good

one on the bottom of the airbox goes to the circle hole on the bit of metal that goes all the way round the battery area, top one goes to the thottle body on the inlet manifold and the side one goes to the hose that leads down teh front of the battery to the wheelarch where the acoustic valve is
