The factory accordion section, several changes in pipe shape/cross sectional area, and the sharp transition from the open air space in the intake box, to the maf tubes, without sufficient volume to be used as a zero vacuum plenum, leave a lot on the table induction wise. Granted it's better than most stock air boxes but the size of the intake passage in the core support speaks for itself.
