I like how the factory air box is made except it's so bulky and takes up so much room on that side of the truck. However, I drive through my share of water and mud puddles/creeks that the factory air box has pretty good protection so thats why I chose to only have a K&N drop in. I'm probably going to make my own piping so I can remove that crappy hat but keep the airbox.


But question, what is this for and do I even need it? Tube circled in red, just wondering what people do with it when they remove the factory airbox

 

Yes you need it...it's the breather for the driver side head that lets vapors escape. You could remove it and put a breather filter in it's place but...yea.

 

im also thinking of keeping the stock airbox, the cone filter gets way too dirty way to quick..also switching over to oiless filter just my .02

 

gotcha...I just noticed that I never saw it with peoples CAIs containing the cone so I was wondering what they did when removing it.

 

I have it on mine. If you look at the pic, where the tube bends down, you will see a blue hose coming off of there. That is the breather. The one on the 4.7 goes to the passenger side. The Hemi goes to the other side. All of the CAIs have an attachment for it.

 

Who makes a oil less filter now. I couldn't find a air hog anyplace so settled for a k and n.

 

'Preciate that buddy. I might try and find a different elbow to work with to maybe help put the box back exactly where it should be. Its just barely off, so I can live with it for now. Whenever it gets painted, it might not look too bad.

Thats what I like so much about yours, has zero "homemade" look to it IMO. You could sell that bitch on ebay, Id buy it

 

at my local advance auto parts...they got all kinds of custom performace air filters..lol, they really only have 2 diff brands K&N and AEM dryflow wich is what im refering to...you dont have to clean it/ oil it..just take it off and literally dust it off with compressed air or shop vac..and has the million mile deal with it too i think

 

Actually, that is the intake hose for the PCV valve. It is in the intake track so that it is filtered by the air filter before it is suckec into the crankcase. It needs to have some type of filtration by a breather cap or hooked into the air intake somewhere.
