I don't really expect any realizable 'seat of the pants' performance gains, but I'm sure the car will breathe better now that the restrictive charcoal filter is gone (without having to do any surgery/cutting) and I am using the K&N E2022 round replacement filter in place of the factory paper version.
I did notice an increase in sound - in a good way!
Best advantage is that now to access filter, all I have to do is remove lid instead of disconnecting the entire airbox and then disassembling it to get to the filter.
Euro Airbox was a direct bolt-in on my 328 with absolutely no problems.

Where did you get the carbon fiber engine cover(#4)? I have a 328i (E92) and can't seem to find one.
