BFI $329.00 not enclosed and not out in the cold air.
K&N $322.00 partially enclosed and not in the cold air.
Airaid $365.00 partially enclosed and uses some cold air from fender connection, would use full cold air if it was fully enclosed

AFE Stage 1 $336.00 fully enclosed and uses cold air from the fender connection.
Volant $405.00 fully enclosed but has hole in bottom for scoop attachment which would be easy to block. Uses outside air connection on fender.

For my money were I to buy a CAI, I'd go for the fully enclosed CAI's hands down. CAI means "Cold" Air Intake. In my mind any CAI that does not get its air from outside the engine compartment is not a true CAI.
I don't have this thing called CAI... I have been wondering about it ever since joining this forum. RB is right. I have seen a lot of pics on here with the filter right beside the exaust manifold, or at least behind the radiator. That is a LONG way from cooler/denser air no doubt! While most I have seen do improve on the air flow coming into the intake manifold, It makes no sense to spend that kind of money and get 'half' what you could gain!
