The quote facility doesn't seem to be working?
The air behind the front grill and in front of the heat exchangers would be relatively high pressure[at speed] with the lower pressure in the engine bay drawing the air through the restriction of those cooling fins. The air speed from the grill through those HE's would be relatively slow compared to the vehicle speed as the incoming air largely diverts around the high pressure area.
The further you get away from the incoming air the less the turbulence and up the top where the OEM intake is placed should be quite stable, relatively speaking. It doesn't matter where the air comes in from as long as it's stable and cool. The negative might be the heat bleeding into the intake from the engine cooling radiator.
In your pic you have the air flow coming from everywhere but where it's likely to be flowing from, which is from directly below and up through the gap behind the intrusion bar and the intake.
Crosswinds and sweeping turns, for example, could change the flow characteristics more, immediately behind the front grill than up the top where the OEC and HKS are mounted.
You have had no problems so in practice it appears not to matter.
