I am gathering my parts to make a CAI for my truck. On the 2006 1500 slt there is a hose that goes from the engine oil fill tube to the factory air box. Is this just a vent? Can put a breather on it or do I need to attach it somewhere? I was hoping to make it out of 3 or 4 inch pvc.

THanks

 

just a breather do what you want with it put a filter on it if ya want

 

thanks
