You will see very minimal gains out of just doing a CAI. The stock intake on the 4th gen Rams is already a true CAI. An aftermarket unit will only give you more noise and slightly better flow. You probably won't notice any power or fuel economy gains. The Vararam would be the one exception to this as it is a completely different style. You will definitely see a few gains with that, especially if you do a lot of highway driving.

I'd personally recommend just modding your stock CAI. Put a drop in K&N filter in it, add a secondary intake tube to the bottom of the air box (lots of threads on this throughout the forum, do a quick search), and change the tube between the air box and the throttle body. You will essentially have a CAI that is just as good if not better than any of the aftermarket set ups and it will cost you less than half the price.
