The filter is there because that is where it has to be. That's the inlet on the compressor section, the only other place that the filer could go is in the wheel-well, and I would imagine it's filled with plumbing. You would be suprised how quickly you can run out of room when doing a turbo install.

Either way, it looks good, I wonder what kind of boost he is running, I don't see any kind of signs of extra fuel management.
