I have been a member to this forum for awhile now but have never posted anything. Recently I took my cai out to give it a good clean with a friend of mine when we came across this tube. He is a little more "car inclined" than I am and neither of us could figure out where or what this tube went to. If someone could please give me some insight it would be greatly appreciated. I haven't noticed any difference in driving and my car holds a solid 10 psi. Please help!! The first picture is zoomed out so you get an idea as to where the tube is, the second pic is a close up. This is one of 2 tubes coming from the same place....it is the tube closest to the inside interior of the car. Thanks!
