Just was looking in my 2000 4.4 engine bay to see where the air filter box is because it's time to change the filter, and I noticed that there is a smaller hose also coming out of the top part of the box, at a right angle from the big hose going to the engine intake. This smaller hose points to the front of the car and then goes down to connect something below the filter box that I'm not sure what it is. Anyway I noticed on my 4.4 this hose is not connected properly - looks like it has come loose. Anyone know what this hose is and what it connects to down there?
