is this important? do i need it? i relocated my air filter and got rid of the elbow and that vacume line was there. can i get rid of it....? if so how..?
That's the AIV pipe that connects to your exhaust. Edit: Since the AIV seems to be a useless part for most people, rip it out and plug it up. I guess it's for faster catalytic converter warmup. It is an emissions device that people remove and still pass california emissions just fine, so I'm not sure how effective it is.
Please stop posting these questions in the performance forums, post them down in the basic or repair forums where they belong.
