Going to install the cobra jet intake on my 2013 gt automatic, noticed that the ford racing cold air intake does not have one of the vacuum lines for the autos. Can i install a breather filter to the line or where else can i connect it?
It doesn't need to be connected. Disconnect that hose from the vacuum block. Place a rubber cap over the tube. I believe it was a 1/4" cap. $1 at auto parts store.
In your second photo it looks like 2 lines turn into 1. They don't, slide that cover back. You'll see a 4 outlet vacuum block. Capping it off causes no problems.
