not messing w/ the intake anymore. i think it's reasonable. the bigger issue IMO is calibration of the MAF w/ respect to the ECU's AFR maps. for me, i think getting rid of the giant airbox all together was a smart move. the BMC is slick & flows well; it also allows me to elbow over to cold air easily.

i'm in that process right now; my intake design is similar to yours (copied in fact) and i am looking to use the 987 airbox instead (3.25" ID) as it gets my maf housing closer to the filter as per oem. i also worry about vibration affecting readings from a maf that is hung out there instead of tied to the air box.
