i have seen many pics of people with cold air intakes, with the tubing going down into the "frame" - some pics have showed the tubing coming forward from under the "frame" towards the front of the bumper (you will know what i mean if you know what a cai looks like). my question is, where the hell is the filter? what kind of filter goes with a cai? is there a cone filter or something like that under the frame behind the bumper where the tubing goes to? i am just curious as to how they put a filter on a CAI? thanks.

 

The filter sits in the front fender and it looks like this.
