Agreed ,air flow restriction relief is not the point of deleting the OEM airbox..
The point is:
1. Intake temperature reduction especially during hot idle/slow-go ,hot weather traffic. At higher rpm/higher road speed = not a huge benefit because of air speed through the intake duct .
2. Access to Bank 1 Cam cover. This can be huge. For some tasks it is the difference between dropping the engine or not .
For example , try removing #1 injector and you'll understand the attraction of deleting the OEM airbox and using the vacant real estate in the tunnel for a replacement airfilter housing. It is a simple, inexpensive,reversible project. No oily K&N filter required :-).
An easily removable OEM Airbox would make the issue moot.
