2012 3.0L air intake duct too RESTRICTED? / MAF qs also

the intake duct opening is covered by plastic panels above and below. please see the diagram i made.

i don't see how a decent amount of air can enter the intake with this setup. please explain if i am misunderstanding something.

what i did was remove the bottom panel to open up the intake considerably.
i noticed a slight increase in both acceleration and engine noise
(or could just be my imagination?)

i would like to hear all your inputs...
possibly a performance improvement?
or safety issue?

------
also, speaking of airflow, i just sprayed some CRC MAF sensor cleaner to my maf when i checked up on my filter. instructions say to spray wires and hot plate. all i could find was a tiny red wire with a resistor looking thing in the middle, so i sprayed that. is it that simple to clean?

------
THANK YOU VERY MUCH FOR ANY RESPONSE!

tbh I cut the piece of plastic crap off of the intake. no idea if it was a good idea or not!

I too thought just as you are now about that plastic mc****ty thing!

It is heated and the resistance changes as air flows across it.

thanks.

yea the spray says not to use if u have a "karman-vortex" MAF sensor, which from what ive read is not really a true MAF sensor. anyway, the outie doesn't have this, so it should be safe...

i hope
