Mark, now I get it. I will definitely check out RPI and order that stuff soon as I can. Btw, removing the Acura plate holder is the first thing I did when I got home.

And the stock charcoal filters can be taken out and simply not used. They are a California emission item which is not even legally required for other states but BMWNA did not want to sell a 49 state version of the car and a Cali version, so everyone gets the charcoal filters. They only effect emissions during cold starts. The rest of the time they just contribute to more resistance in the intake track.
The total of these changes are you can move move air into the S85 V-10 engine - a good thing! RPi has instructions so it is within the range of being a DIY mod. But search the Board on how to partially remove the front bumper to get access to the area in front of the radiator. Don't just yank the front kidney grilles out. Thieves do that but then they don't care as much about broken mounting tabs.
Be sure to order the block off plates - they are not included in the RAM Air kit (but they are cheap). The RPi folks are known for their customer service so it should be a pleasant buying experience. Ask them about the trunk placards if you have a sick sense of humor.
