custom CAI
This is for a 99 a4 2.8 Q.
I'm making a custom intake from the throttle body all the way to the box. Also making the box. I'll be using a cone type filter. Only real question I have is this: I took the box out and noticed a hose connected to the bottom of the air filter box. I know there is the intake snorkel on the top to push cold air in, but what is the rubber hose for on the bottom and where does it lead too? I was guessing it realeses gases or the intake sucks in some gases from the hose. Anyone care to share what to do with it or what it's used for? Thanks, |
