I am looking for a filter that is smaller diameter and not tapered and probably a little shorter.
BTW, your filter hits the IC outlet.
what about this ? the deapth look about right but it would have to be narrowed.

The T/A ones on eBay look very big, those would definitely require more work to fit.

I wish they showed the underside so we could see how it mounts.
studs? tape?

Of course, it doesn't help having MSFITOY munching on popcorn. Wash it down with a couple of beers and jump in here!

You won't need a taller HDI. It only sets about an inch below the hood which is just enough room for a decent gasket. Whether you have the scoop attached to the hood or rising through the hood you need that gasket clearance.

Something like this ZX hood scoop could work

IMO, the location of the Mini's airbox is in a poor position for direct ram being situated in a low pressure zone away from the center near the cowl vents...you will need a much taller intake ram of something rather tall to reach into the high pressure flow...
The Z's location is more suitable due in part to it's central location closer to the high pressure zone near the windshield's center base...

K-huevo is refering to a mod that I call Split Air Intake (SAI). You do not have to cut the hood and achieve the same thing that Onaslead has done. You can do it by using the existing opening for the IC. The idea is to take advantage of the oversized IC opening, in comparison to the stock IC. By removing the IC cover, splitting the air flow to allow the air flowing to the IC to go there and tunnelling the rest of the air flow to the Air Filter. I also use the stock opening to tunnel more air to the airbox. So you get 2 sources from the front. The plastic wall that is behind the Airbox is drilled to have a couple of holes to release some of the backpressure created when the two air sources from the front are flowing. But, by keeping most of that wall, the air is forced to change direction to the airfilter. The holes in the back wall also help as a cool airsource when the cars is moving slowly. It is extremily low cost, I did all the cutting myself and have been driving it for two years now.
For those of you who are going to ask, why do you want to remove some of that air going to the IC, that sounds bad. No, it is not bad, it is better this way. Because the way the stock IC airflow is now, the extra area to the right that gets air but does not have an IC surface below it is causing backpressure and a vortex over the IC. That vortex is created as the air flow to the IC in a 90 degree directions of the air flowing directly to the IC. So by removing the 90 degree air and channeling it to the airbox, you allow air with more velocity and correct direction to flow to the IC, no Vortex.
Some other people have come to the same conclussion, like M7, with their DFIC scoop that addresses the same issue for the DFIC and a NAM member that made his own scoop to address this issue only. I figured this out about 2 years ago and build the earlier versions of SAI.
If you agree with me, you will also understand why I do not like the air diverter from Alta. It is better than stock, because it channels the unused airflow in a near 45 degree angle, but it also creates a vortex.
SAI can be used also with HAI or the M7 AGS. My hope is to marry SAI and M7 AGS, if I can get Peter to ship me one.

bomboasy, I see exactly where you are coming from. I have repositioned the foam seal under the hood to come down directly around the core of the IC, onto a "shortened" stock diverter that no longer hangs over the IC outlet.
Your idea is good, but are you directing the non-IC air from the scoop through a sealed tube to the air filter?

On another note, I met a fellow MINI owner last week. He brought his LY/W in here to get the emmisions done. Come to find out that he has a shop and does carbon fiber. I could present him with a scoop idea. I'm sure fabbing that STI style scoop to fit the MINI hood wouldn't be too hard. I think it would be tall enough to grab the air that MSFITOY was referring to.

! Negative, negative negative . Where's the "scoop" & "rear wing" can do mindset
? go back to eating popcorn
(lol) 

I can appreciate as you go back towards the windshield the low pressure zone increases. If this is an issue then I would say forget the shaker style and add a scoop affixed to the hood and bring it forward until you reach the high pressure zone.

Honestly, the best ideas to take air in are in these order:
1-Lower grill area (bumper level)...highest pressure zone...closer to center the better...
2-Upper grill area...again, closer to center the better...I know most people are not buying my version of the AGS as a true "Ram Air" design but that's debateble...
3-Right where the IC intake is but sharing the air is at best a compromise without a wider scoop design and is also difficult due to the height restriction...
4-Above the TB location as show in the race car example...
5-Above the airbox...needs tall scoop to work...
6-Through the cowl...same problem...low pressure zone...needs tall scoop to work...the ones that are sold are not tall enough to be functional...

That definitely looks like it would work.

Sorry no I don't. I just happened to think of that scoop while I was contemplating posting a pic of a NACA duct.

Which would work well in this instance and address some of the issues raised by MSFITOY.
NACA Ducts has good potential but requires a fairly flat surface linear to the airflow in order to function properly...
"NACA stands for "National Advisory Committee for Aeronautics". NACA is one of the predecessors of NASA. In the early days of aircraft design, NACA would mathematically define airfoils (example: NACA 071) and publish them in references, from which aircraft manufacturers would get specific applications. The purpose of a NACA duct is to increase the flowrate of air through it while not disturbing the boundary layer. When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner, but without the drag effects of a plain scoop. The reason why the duct is narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area slowly so that airflow does separate and cause turbulence (and drag). NACA ducts are useful when air needs to be drawn into an area which isn't exposed to the direct air flow the scoop has access to. Quite often you will see NACA ducts along the sides of a car. The NACA duct takes advantage of the Boundary layer, a layer of slow moving air that "clings" to the bodywork of the car, especially where the bodywork flattens, or does not accelerate or decelerate the air flow. Areas like the roof and side body panels are good examples. The longer the roof or body panels, the thicker the layer becomes (a source of drag that grows as the layer thickens too)."
Problem with our Minis is that they're short, round and stubby...

A NACA duct would work well right above the throttle body location.
How would we seal a filter to it?
EDIT: ok so much for that
What about an opening on the flat right inside the drivers' headlight?
