You don't understand air flow and turbulence that's why 
(joke). But in essence as the air is flowing in its hitting that ridge first. The path of least resistance is a gradual gradient. On these airbox they have manufactured a bump surrounding the mesh/TB opening. This is because air prefers to travel over the smoothest surface, and as a slight curve is smoother than a right angle the air will flow with less resistance.
As cold air intake are Ineffective I've had to think laterally of other possible restrictions. Which is why the pipe is now perfectly perpendicular with the airbox opening, again to smooth out the airflow.
Think of it like the stock k11 manifold, loads of sharp angles and ridges. Bit smoothing and grinding to aid flow and gains are easily had, as seen in franks manifolds.
If it works for the exhaust it should in theory work for the inlet too. Does that make sense?
