GTST... Whats that old saying. Great minds think alike.
I did this to mine some years ago.
Standard R32 Airbox.
100mm DIA hole in the bottom of it, 100mm dia hole in to the inner bumper air intake directly under the airbox.
2 x 45degree PVC pipe angles
One slips in to the other, one points slightly forward in to the airstream, the other points in to the airbox, you then trim the one that enters the airbox so that its nice and clean in the airbox.
It looks stock, paint it black modify the std cai and it can't be seen.
