Yes! and as there are two of them (each with its own filter) I find it hard to believe that is where a bottleneck could be. And, if there is any restriction in the induction system at all. Even at 7,000 RPM I would think enough air enters the engine.
Aye most intakes are pretty well optimized from the factory which is why their is very little improvement to be had without a tune,
that said nearly all intake are setup to isolate the cabin from sounds in the engine bay and will include expansion chambers
or odd-routing to do so.
Those small changes do limit the car when you start tuning and trying to squeeze every bit of power out of the engine.
This is just an example from the G37, but it's the housing just below the vacuum line.
