First picture is mine. I have PFS intake so there is 3 hoses at the top of the box with the bigger one underneath, what does the 3rd one from the left to the right do (it is very loose)

Second one, not my picture, but the hose is off/ripped just curous as to what it could have effected and what it does? Just learning. I searched but its hard to look up something you don't know.


Also is there any diagrams of the engine bay, besides the vacum hose one, that explain which parts are which?

Thanks Ryan

 

Thats for the air pump. There is supposed to be a line that goes to your intake otherwise you will be hearing that "moo" sound when you accelerate.

Yeah thats the airpump hose, I have the Apexi intakes and its hooked up to them and it still does the "cow giving birth" sound @ ~1100rpms.
