There is no power, it's a waste of time. You would have to go WELL over 100 MPH to even gain a fraction of a psi. Also, I wouldn't reccomend making your "CAI" down by your foglight, unless of course you want to hydrolock your engine.

Stock air box w/K&N. Custom CAI!!
K&N cone filters rated @ 8-900 cfm
K&N flat filters rated @ 450 cfm
What I did ensures constant cold air plus at speeds over 70mph = 1+ psi ram into the intake.
Lots of diff opinions on what works best.....I like my setup seems to work just fine.
$45.00 for the filter.
$15.00 for the CAI parts (Home Depot).
