Re: K"&N CAI Intake install question
The vaccum hose is a simple, short, cheap part. I cannot recall diameter, but believe it is shown below just above center with the red dot at the opening (this was shot from my CAI replacement). Your dealer should get it reasonably cheaply, otherwise you can get one from any decent auto parts store, if you even need to replace it at all.
A CAI is a clean, simple mod and will generally not impact your warranty. My Jeep service tech has one in his Hemi and recommends it. Search the Magnuson-Moss Warranty Act in this forum for more comfort.
Please post up some photos of the K&N, I didn't realize they finally got one issued for the WK2.
