Hi,
- what are those 2 thin air hoses running across of top of ic tubes? One of two is loose from something. Or should it be that way? Gasping free dust
- could someone kindly post schematics for air piping in engine bay for future reference. There are quite many of them and if there should be need to dismantle something-some day-for some reason ...
Thanks.

Edit, loose one in my car was airbox related, checked.
