I've gone with the sealed box option and an Air Raid TBS. I found a good deal at truckcustomizers.com. I am waiting on my shipment now. I hope to have everything installed by this weekend.

 

On my end I did the sealed air intake using the stock box. So far with the completion of the first tank my mpg went up almost mpg, given similar travel and driving habits from prior tanks (approx 85% city and 15% highway). Not bad given the first half of the tank or so went to allowing the engine control computer to recalibrate for the increased air flow. I will post any changes once I finish a full tank with it installed and calibrated.
