The spacer might very slightly lengthen the air path (3/8"), but only in the upper plenum and the 6 connecting passages down to the lower plenum. The runners from the lower plenum to the heads are the ones that control the powerband due to their design (length and area).

 Because we all know that if the intake spacer was increasing our powerband, that thing would be at least $300, not $80.
