I am a rookie here too... but...

why is the comptech icebox so special?

Why use it on the stock intake?

I checked my intake box, and it seems that there's a tube attached to it that is sucking air behind the turn light.
That's the original intake box too.

I thought the point of the icebox was that you can adapt it on the comptech short ram intake. So what the point using it with the stock intake pipe?
