You loose that in all the areas.. pretty sure the competition knows that you need other areas to pull air from but that messes with styling. Pats stuff definitely isn't cosmetically pretty..
3 factors that really help..
Shortest direct path
No restrictions
Coldest air..
All those items increase flow increased flow lowers the iat coming into the motof if this happens you see more power.. timing.... knock retard ect..
I kinda thought it was bs until we went out and tested all the stuff same day same temps..

Yeah, that makes sense. But my question is whether 800 MV or 900 MV was more reported airflow. The MAF table in the ECU uses HZ.
The reason I ask is that my Roto-Fab seemed to substantially over-report airflow. That equaled less boost and rich mixture. These engines can actually get KR from being too rich.
