Hello people I'm new here, I was directed to the forum while asking for advice somewhere else. I own a mk3 16v, here is a link to my neglected build thread http://vagdrivers.net/forums/index.php?showtopic=26546&hl=jonnyp16v.

Ive gotten a bit further in my plan for installing the induction kit but I still have a few questions.

What is the function of this pipe running into the intake pipe?
