Hi guys,

Can anyone help me out and tell me what this doo hickey is and what is its importance. It has a black and pink plastic vaccum line coming out of the left side of it.

 
It stores air so when your under boost your vents don't move from floor to dash to windshield.its a must have if like A/c blowing in your face.
