That's where the air intake for the stock airbox already is...
I considered doing this, but first I used "Torque Lite" for my Android phone, and I could see the temp reading from the IAT sensor. On a stock intake at highway speeds it's not that high, it actually approaches the reading on the dash from the outdoor air temp sensor. It does run up when you're stopped with a warm engine -- but when stopped it does not matter all that much b/c you're not moving. Get moving for a bit, the IAT reading runs back down toward ambient.
...seriously, check it out.
...point is, when you are moving and want to make HP, the stock intake acts like a CAI.
I will hand it to you, you did a nice looking job on the CAI you made, though.
