Is there any potential gains by removing this two also since you are already cutting up the box? Do the aftermarket replacements also have those? Just seems like anything in that area is an obstruction.

Those 2 "air veins" smooth the air over the Mass Airflow Reader. If you remove them, you will have idle issues. (I know this because years ago I did the infamous "de-screening" on my GTO.) To resolve the issue on my GTO I went maf-less and got a Speed Density Tune.
GOOD aftermarket intakes keep those fins.

What I removed from inside the intake box looks more like support and sound deadening. Most of what is inside the air box isn't "finned" to let air through.
