Best CAI for Clubman?

[CoachWes]

Since I am new to the herd, I wanted to ask for advice on CAI's. I have seen several and each thinks theirs is "best". Can you all give advice, do's/don'ts, and/or likes/dislikes on the various CAI out there? I have a 2008 Clubman S.

Thanks for the help.....

ALTA is my personal preference!

Guy's come on. I expected a little more activity here. ..... (crickets)

I just had the DDMWorks RIS installed a few weeks ago. Quality fit and finish. A noticable difference with all around driving. One interesting thing I noticed yesterday is that after a trip to Raleigh, which I do every few weeks, my gas mileage we 1.8 MPG higher than before the intake install. It is a little on high side cost wise but worth it to me.

I only install DDM intakes on R56's at the shop. I don't have check engine lights from them.
