the MAF on the filter side doesnt have a round hole, its the square flange, cant really band clamp a filter to it. you would need some kind of flange adapter made up.
i dunno where you got that CAI you have now, but ive never seen a kit that just has the top tube like that. I think it would be more beneficial to you to just go buy a MAC or BBK cold air kit for it, and they come with the big open filter with it that goes in the fenderwell. if you want it for show, the JLT kit has the filter sitting in the same position your K&N is in, just without the airbox, its all open and colorfull and such. I think the MAC, BBK and JLT ones are around 150-160 bucks. but they are complete and look good, all chrome and shit.
