I posted a video thread the other day and got a couple PM's/posts asking if I could post pics. Keep in mind this is a prototype intake, so the final product may look slightly different! I decided to post pics (and paste the review) here instead of the photo section as the only ones really interested in this part would be 328i owners. Please excuse the dusty bay

From in the cabin it is noticeable if you know what to listen for. When trying to point out the sound to passengers that were not car enthusiasts, they said they couldn't hear anything different/had no clue what I was talking about. All in all, the intake was a fun mod with only slight performance benefits but a large increase in sound/driving experience. While it increased some engine noise and the diverter "PSHH," it did so at levels entirely acceptable.
