i put a aem dryflow cone filter in the stock airbox and made a custom pvc pipe to connect it to the opening inside the airbox that goes to the maf. dremmel'd out those baffles. Also ran hose with cone scoop from lower right grill. Trimmed out the back of the grill on one side and ran the scoop and hose from there to the airbox and cut a hole in the airbox to put in the pipe and sealed it. Also did a hose from the side of the radiator to pick up the cold air bouncing off that.
Car runs amazing with this setup and pulls better from 4500 rpms and up to redline. Buddies have en noticed it and joked that it feels like vtec kicked in. Perfectly complimented by an exhaust.

Well, I didn't want to share all my secrets just yet, but I'm working on a setup similar to this: http://forums.swedespeed.com/showthread.php?83377
I'm still using a k&n panel filter, but am running a hose or 2 for extra intake. On some of the highest flowing air boxes tested, the larger the intake area before the filter, the better. Obviously, there's more to it than that such as the shape of the air box, filter size, smoothness etc.
Hopefully it gives you guys some good ideas. The thing with ram air is, there's all kinds of wild claims on the internet. I still have to pick up a differential pressure gauge, so I can actually measure pressure drop. The bottom-line is this: some think ram air can give "boost" at highway speed. In actuality, the best you can hope is to reduce pressure drop at high rpms. The 2.8 engine can flow a lot of air, especially the 30v. If you can supply the engine what it can flow, the results will be very good. Plus this is a really cheap mod!

haha thats where i got this idea from swedespeed when i was looking into buying a S60 T5. Alright get ready guys ill post the pics up and give some explanations. Not meant to be the prettiest inside the box, all about the funtion so please don't hate on the cleanliness hahaha.Sorry it was raining and i was at work so i kinda took these quick on the blueberry. here we go:
Here is the front grill. I cut out the back part of it and glued the scoop and hose to the back of it.
Thats what the airbox looks like on mine from the top.
The yellow stuff is the pvc cement because i smothered it on the to make sure that pvc pipe was complelty glued and sealed to where to opening to the maf is. I used 3" pvc pipe because it worked with the AEM dryflow filter. This filter with the pvc pipe fits perfectly inside the box and easily can be opened and removed as pictured. I also sealed the connection between the pipe and filter with silicone and only had almond color left hahaha. Aem filter is solid and nevers falls off and never trouble code from any of them sensors,
That's the view from the top of the bottom part of the airbox. You can see the two flex hoses i ran into it from the front grill and radiator. Best part is that this setup still retains oem draining if water was ever to accumalate. Never has though.
Just to show how the flex runs from the side of the radiator. I cut a round hole through the rubber barrier wall that is there and it holds that hose in place which scoops up the air that bounces of the rad.
Thats all i managed to take. Hope this helps and inspires you guys to try something different and build your car the way you want it. Feel free to ask questions, i am no expert but i would love to help

I like the fact that you used one of the factory grills to pull in more air, kudos

Nice love that intake set up and for the guy that started this thread i think you should just go to home depo buy some insulation and get a piece of metal plate(SHINY OF COURSE) and mark the dimension's of it cut it out drill some hole's find a good place to anchor it to and it will look good and it will save you a lot of money and i bet it will take you like one sunday afternoon and a couple of beer's 
i think it wont even cost you more then 100 buck's in my opinion.

hahaha you are welcome. You guys should try it out, in combination with the exhaust, it really freed up the congestion that was happening from 4500-6000 rpm. It just breathes happily and therefore you can feel that it is pulling better through that range. With the air being force fed into the box like that in addition to the stock part, the filter is seeing an abundance of cold fresh air and will never have to work hard to pull it. I might put some sort of heatshied around the outside of the box closest to the engine that is black just so it looks normal and also helps radiate that heat away from the box that is comming directly from the engine a couple inches away. Goodluck.
