Vacuum box on intake?
What's the black box next to the throttle body connected to the intake. I know it's a vacuum line but what's it actually called? And what's it's purpose? Has anyone removed it?
If you're talking about with I think you are I've heard it's like a sound dampening chamber to cut down on the noise the air makes through the iac. It can be quite noisy without it. I don't think it's considered vacuum since it's upstream of the throttle valve and iac valve.
I'll try to get a picture of it. I ask because I bought a used k&n intake. It fits on my truck but it needs motivation, one of the problems is this little black box is getting jammed up and bent outta shape to fit the intake. So I was wondering if it could just be removed.

Haven't been able to get out to my truck but here's a decent picture... it's the little black box connected to the intake on the right side just before the throttle body. in the middle of the picture.
