Yes I would agree with that, based on shaking it. I may cut it open and if I do I will report back.
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.
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).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 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!I drilled holes in my Helmholtz resonator to see if it would change the intake sound.

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