Stock airbox top inside porting?

[RMinNJ]

Ok I read about here and then saw the white charcoal filter on the top inside of the
stock airbox. Reading here it's for hydrocarbons/emissions.

If I remove this small white filter I assume there will be no emission codes thrown.

But I did notice the top inside of the airbox has some vertical ridges underneath the
white pad...it seems to me they are there for some offset and airflow through the silly white pad.

If I remove the pad it seems to me the all the plastic ridges represent a baffle (slight I know) to air flow.. can I not port/grind these down so the top inside of the airbox is smooth? Or are the vertical ridges designed to be benefitial to airflow (turbulance reduction to the MAF?) ?

The ribs are reinforcement for the airbox, you can remove them if you wish.

You're not going to see a gain in doing this, you're only going to potentially make things worse.

stock airbox porting

Thanks guys...thats why I'm asking here.. I have no problem leaving it alone.

I know some folks have removed the white charcoal pad...I'll remove it later in the car's life
when it get dirty or frayed. It says right on it it's a non-servicable item. I still question the wisdom of them putting a small peice of paper/fabric right in the air intake..despite how well
they think it's attached to the airbox.
