The European BMW Performance intake system found HERE
could be bought separately but it does not mate with the US Spec air box. It utilizes a majority of the components from the N52 Euro air box which are not found on the US spec airbox.
If you'd like to utilize your US Spec airbox there is a different BMW Performance intake system you would use which does not take advantage of the Euro airbox design but does fit the US spec airbox.
I'm sorry you where on hold for so long, I'm here five days a week and usually am able to answer questions rather quickly. In the future feel free to blast me a PM with any particular questions and I'll get them answered right away.
