I was checking the specs and that's ultimately why I pulled the trigger. I only halted everything when the box was labeled with '11-'12 Cooper S and Clubman S.
The whole experience of dealing with K&N was weird. I called twice asking very specific questions and neither call seemed to yield much of a result.
Now, I'm happily surprised about your comment regarding a high-flow filter in the OEM airbox. I've already got (what I think is) the best filter for my car in there, which is the other K&N part.
I know it's a dumb question, but where exactly can I see the "type" of engine my car has? I didn't see anything like N18 in the manual or on the web.
My backup plan, which may now change, was to install the intake and remove the airbox cover in place of a mount/casing for said intake. I really am chasing that turbo sound as well as whatever performance increase it'll give me over the airbox. What do you think?
Also, thank you for the well thought-out responses. I'll buy you a beer for your troubles, just DM me your best payment info.
Edit: The new intake I ordered is the K&N RU-1540.
