If I remember right the Air Raid brand boxes are sealed on top. I think you could add a "scoop" or intake of some kind around the grill or headlight and make it a pressure fed system. (maybe under the bumper or between the bumper and grill?)
I have the K&N style CAI. And it did make a difference, but the top edge of the filter enclosure does not seal tight to the hood. That really minimizes any benefits I should be seeing. One thing it did was make the intake a lot louder. But only when I really have my foot in it.
I am interested to hear what they say about the headers. I have not done anything with my exhaust yet but plan to this year. I want to see what system offers the most improvements.
