For once and for all, would somebody please give the advantages and disadvantages of the following systems: Stock Air Filter
K&N Drop-In filter
WAI

CAI
I'm looking for fuel mileage and all around lower-end performance. Would an expert please tell me the best option. There seems to be some confusion between the types of intakes. Thanks
(Maybe somebody could make a chart w/advantages vs disadvantages)
