Follow it back to the UIM and remove the hose and cap it off.

Right behind the throttle body to the right is where the VFAD hose connects to the UIM, unplug hose and cap that long nipple with something to make it vacuum tight

Throttle body is removed in this pic, but you'll get the idea.

kondypl just want to verify something, when you installed the intake did you remove the front bumper and actually remove the VFAD assembly? We kind of just assumed you removed it by telling you to cap the nipple on the UIM. It's just common practice around here to remove it when installing an aftermarket intake.

The VFAD is the Variable Fresh Air Duct it purpose was to reduce noise at low rpm and then open at higher rpm to increase airflow, because of this it's restrictive which is why it's usually removed.

Refer to the first 4 pages of these instructions on how to remove it:

Well, I was wondering if you had removed the VFAD, but didn't want to ask for fear of being razzed. Next time I will ask!
