What’s this? 2025+ Air filter cover piece

[craigt502]

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.

The hybrid also has one (pic below) in the upper air box! My curiosity was piqued so I did the scientific thing and googled "what is the little black filter looking thing in my maverick airbox?".

It seems the answer is that it is a passive carbon absorption filter to capture vapors that may be present in the intake after the engine is turned off.

Thanks! That makes sense after seeing and feeling it. Soooo who is going to be the first to remove it to see if makes any difference in air flow? Ok I’m sure you wouldn’t actually feel a difference but I am sure tempted.

Not it.

Don't do it.

That just makes me want to do it more!

Its an emissions component. Removal is a federal no-no.

That wouldn’t deter me much. I’m sure all the aftermarket intakes out there don’t have such a component either.

It is an EPA requirement. Maybe that will motivate you even more

Useless on the EB? Any vapors escaping from the closed throttle body would have to work their way back up through the inter cooler, travel through several feet of intake tubing before reaching the air box lid.

I don’t think the S&B aftermarket airbox has the filter? Maybe that is why it is illegal to use in California I check mine when I get it…

As an older person I can assure you that even tiny amounts of vapors can indeed travel far.
