I recently bought a dragon air intake for my 2002 Honda Odyssey V6
On the stock intake, there is 1 hose for the front side, and 2 hoses for the back side. The back hoses, one is very small and the other is for the vacum,.
What is the small one for, and how do I conect that to the other intake.
There is only one hole at the back.

Please help!!!!
