You want one that goes from the TB to the MAF, and from the MAF to inside the fenderwell. The one's that leave a conical filter hanging off the MAF just suck in hot air from the engine bay, defeats the purpose.
With a cold air kit, your basically basing choice on the looks of the kit, because they all work the same aslong as they are the fenderwell style.
The factory box is a cold air intake. If you like the looks of the fenderwell kits, go for it. But don't expect any performance increase. See the link for a comparison - no difference at all between a CAI and the stock box with silencer removed and a flat panel K&N.
On a side note, I LIKE the bling bling, and the BBK CAI has been great so far. Good fit and finish. Since its all for looks, and I would get one that you think looks the best.
