Nice little write up man. Just went out and did this.
I have the Steeda CAI so I can't comment on how the stock airbox sounded with it but strangely this did seem to clean up the sound for the Steeda unit. Could be in my head though.
Interesting hose idea. Definitely a bit easier than newmission's. Although if you aren't planning to add that to the bottom of the airbox I'll be extra interested in what your plans are.
