airbox and some sort of scoop to direct air from the fascia's inlet into the filterbox. The trick to doing this is to make the incoming air pressure equal on all sides of the filters. If the filters could be positioned such that they point straight forward and have a box around them with only the front side open, the airflow and pressure would be pretty much equally directed around the filters and it wouldn't cause issues with erroneous mas readings due to turbulence. There are quite a few ways I have thought of doing this and I wouldn't go with the example I gave as it would take up too much space, and in that case it may require some sort of guide as you suggested. I'm sure I'll come up with something good though. :)
