Personally, i'd say the cold air intake..on some conditions. Some of the cheaper cold air intakes have some really crappy MAF sensor err plugs (the correct term escapes me at the moment). if everything is solid, then it should out perform and give better mileage over the drop-in, can't forget the amazing sound
. Still, it is a bit questionable.
If your like me you'd get the CAI for the power and economy, but you can't go wrong with the drop in and it's price!
