Looks like a desiccant pack with the non woven on one side and tray on the other. Is it filled with granules/beads?

Some folks Just gotta tear things down,
When I see something like that I give it no thought. I leave it alone.
Ford decided to put it there, good enough for me.

Yes I would agree with that, based on shaking it. I may cut it open and if I do I will report back.

I have seen those in other air-boxes, a carbon pad. I do not think they are emissions required maybe specific states. On the EB with those I have seen they do not hinder any airflow. Fords version of the pine tree air freshener for the CAI??

The way it was positioned in the 2.0 air box, I think it did hinder airflow. Granted, I do not think removing it will be any noticeable improvement to the driver but if I was able to test it scientifically, which I don’t, I bet airflow would be better without it.

Back in my younger days of modding cars, a free mod you could sometimes do was gut an air intake box. Some factory intake boxes would be covered in extra plastic pieces likely for sound baffles and more rigidity.
I was curious to see what the 2025 intake looked like. It’s fairly “clean” no material to really modify or remove. Except what the heck is that for?! My hope is it’s just some sort of sound baffle and removing it would be a free mod to improve air flow. But that may be wishful thinking.
Edit: I removed it! See post later down in the thread.

I drilled holes in my Helmholtz resonator to see if it would change the intake sound. It did a bit (search “holes in my Helmholtz to view that thread).

A few commenters cautioned that it could upset the delicate balance of the OEM airflow programming).

I did not “call BS” on that - but I thought it lol. Removing that EPA mandated carbon vapor absorption pad should not change the airflow much either I’m betting…

Anyway, my Helmholtz Resonator will soon be completely removed when I install the aftermarket S&B Air intake:)

I just read that thread. I would’ve never thought that was a Helmholtz resonator on this engine. Other factory resonators I’ve seen before are very small in comparison. I would’ve just suspected it to be more of a “fresh air tank”. Fresh air tank sounds stupid but I don’t know how else to describe it! 😂

It is just a hollow space. Peeking through the holes, I expected to see baffles or something. Nope, just an empty space.

The holes are taped over now in the hot weather - as I imagine air gets sucked in from the engine bay during high rpm’s?

The Helmholtz Resonator near your tailpipe is minimalistic too.
It works though:)

Few weeks later, all is still well.
I am not saying this mod resulted in better MPG. But since I did this, my average calculated went from 31.2 to 32.1. (I’ve never reset it)

Well I removed it! Pretty straightforward, cut to remove it, clean up some of the rough edges, then clean it out good so no plastic goes into the engine. I haven’t had a chance to drive it much but so far all is well!

Let’s just disable. Undo several hundred thousand dollars of FoMoCo R&D.

We don’t really know why it’s there.
So let’s toss it over our shoulder and see what happens.
Twenty, thirty, forty thousand miles later a check engine light pops on.
One Ford diagnostic fee later, about $125 they find it.
It was cut out so only way to fix it is a new breather box top.
Betcha it’s way north of a C-note.

:XD

So sorry, I gotta be me.
It’s Geezer wisdom,
Just block me, I don’t know shit.
But I do know Ron White says:

I understand your position and I would also take that position on some things, but I currently have 0 concerns here. I’ll certainly update this thread if any negative effects occur.
