Thottle body
 

What is the reason for the water hose connected to the thottle body. And if I bypass it will I get cooler air to my stang

Exhaust runs up through intake to egr spacer. There is a coolant passage in the spacer. So keeping lines connected will help to cool incoming air.

egiap's 5.0 is correct, EGR gasses (exhaust) run up through the egr spacer and then into the intake, the coolant lines although being hot coolant is cooler than the exhaust gasses and supposedly cools it down, so i'd leave them there if i were you, unless you disconnect your EGR
