Drivetrain Cold air intake - worth the money?
Hyperblue - the intake scoops may not help much excepting in bling, since the airflow over that area of the car is not "laminar" - flowing smoothly along the body contours - but rather it kind of "bunches up" at the base of the windshield. It would then be a good source of pressurized air with or without the scoops.
Here is what I have noticed.Changing out from a regular to 15% reduction pully helped the power a good deal. Supercharger wine higher pitched.Ik 22 plugs-no change.Webb CAI and RAF a little more power with slightly better low speed torque. More noticible supercharger noise. Milltek catback exhaust-better power still and better low speed pull.Exhaust balances out the louder supercharger noise a bit. With these mods my 06 feels a little quicker than the new 07 I drove at the dealer. I may go with a Giac next.
one thing you're forgetting is that with a good intake your mileage will go up, and will pay for itself in the long run, as long as you drive reasonable most of the time.in my opinion, go with a good intake. it'll look better, and the risk of getting grime, sand, etc., is not worth the few dollars you save by going by an cheap.
Especially if you have a Mustang or BMW with air being sucked from below the bumper! With the Mini's high air filter, just make sure there's a way for the water to drain before being sucked in. The only concern I've had about the "window vent air" is when that truck in the opposing lane throws 10 gallons of water on your windshield and it heads "down the drain" at the bottom...
Thanks for the feedback guys. I got another idea which I've been thinking of doing for quite sometime now. Well, here goes.. If directing more air to the intake is crucial in terms of hp gain, would it be possible to fabricate an additional pipe so it would draw in more air from the bottom bumper cover? To do so we would have to cut an opening at the bottom of the airbox so we can install a flexible pipe and connect it somewhere frontal so it would ram in more air.

Right now I have that hole plugged up and all related parts removed, i'm still trying to figure out the best way to use it.
The existing factory hole is located on the frontal side of the airbox which is like 2 1/2 inches max. What I meant is to create an additional hole at the base maybe 4 to 5 inches in diameter so it would compliment more airflow. Don't take my word for it since I'm not sure if it can be done. We'll have to remove the base to see how much room we have down there.

There really isn't any other way to get air to the bottom of the box effectively without using the stock hole.
One other option i've been considering is a separate hood mounted scoop that will look like the stock bonnet scoop, just smaller and will feed the top of my air box directly.
Pardon my ignorrance but any reason why you would wanna plug the stock hole in the first place? If I remember correctly, there isn't much room for a round 5 inch hard pipe beneath the airbox cover. The only way of fitting one is to get the flexible aluminium pipe like the ones they sell at home depot and shape it according to the hole you've cut. Now you'd have to find a right spot for the air inlet.

Air inlet for where? the top or bottom?
Trying to cool the air in front of the supercharger really isn't going to produce noticeable results. You've got to cool the air after the charger. The only way to do this is with an increased surface area air/water heat exchanger. There are a number of larger intercoolers out there. I'm looking for an intercooler for the GP model. (OEM vs aftermarket)
What I'm trying to say is hook up a 5" flexible aluminium pipe from the base of the stock airbox and connect it to an inlet opening made under the bumper cover.
5" is rather large, and I don't think you would be able to fit it.
before you change to an alternate air intake path, be sure you have decided not to use your car in an SCCA or MCSCC or NASA event. each of these will penalize you for a cai, but all three allow for a change (or elimination) of the filter.; If you do a search, you will find that the filter is the issue, not the intake path. If you just want "noise" and don't care about the competition rules, then buy the pretiest CAI.

One other thing to remember, we are dealing with a forced induction system on the car. It will perform very well if it has aceess to air, no need to "ram" more air into it. Most of the CAI on the market for the "S" remove the panel at the rear of the airbox to allow more/cooler air to be drawn from the cowl vent at the base of the windshield. This has been tested by several members to be a more than adequate air source.
