Longer tubes should move peak torque down if they do anything.
The major advantage must be that they just sit in front of instead of behind the radiator.
I've yet to see clear dyno evidence where any of these aftermarket intakes outperform high flow panel filters + smoother tubes, at least on the 370Z. The OEM airbox already ducts cool air in from the bumper and has excellent heat shielding.
It looks restrictive, but it's really not. Nissan did a good job on this airbox.
