i wonder if the flow charicteristics of the 996 air box don't translate well to a straight-through MAF housing. on the 996, the MAF is VERY close to the airbox inlet & not entirely round.

I recently installed 987 airbox & MAF tube with 997 plenum "T" & T/B, then reflashed with '00 LEV 996 map for my 3.6 boxster engine & it seems to work very well. Pulls to 7400 very smoothly.
