OE intake mod?
 

I just purchased the truck in my sig and was poking around under the hood checking things out. I pulled the intake tube off and noticed that about midway down there is a blue in color foam looking liner inside the tube. What's the deal with that?

I wonder if it's anything like the 10-12s? If it is, it is simply a baffle that can be removed. Its suppose to help direct air flow and quiet the intake. I'm not familiar with the newer trucks.

I found the air foil thing that controls flow of air. The blue matting I bet is to get rid of turbo whistle....who doesn't love that sound.
