Even the stage 2 SI Pro that you are referencing doesnt cost $900. You can get it for $700-$800 and perhaps less than $700
All off you should know because you are E90post.com members you get special pricing way below that marketing price.
The stock box intake air travel goes IN > UP > DOWN . It has to bank "SHARP" corners with through a SMALL space
The aFe intake air travel goesn IN > DOWN. The is not sharp bank cornering of the air. The air turning is ample wide with a rounded down "Y" spliters into the turbo inlets.
Here is a tech sheet on the airflow. I have sealed the box so there should be less restriction on the stock snorkel.

The reason this intake won't do much vs. the OEM airbox is that the inlet is basically the same size as stock. Those little snorkel openings are each 1" tall by 6" wide. The square opening on the OEM intake box is around 4" tall by 3" wide. Both are well matched at around 12 square inches. The problem is they need to be around 16 square inches+ to support higher boost levels at higher RPM. From what I can tell this AFE airbox will still be limited to around 12 square inches with the combined inlets.
