Injen Intakes Installed! Pics, Vids, Dyno

Most of gains are in that last 500 or so RPM of the rev range.

That's not to say it's not worth it, but on it's own the CAI will not give you much. Combine it with exhaust and a tune to take advantage of the extra airflow and then you'll really see gains.

If you are really concerned with peak numbers, the Stillen G3 intakes definitely seem to be the best out there in that regard. You could expect to gain a few more hp with the Stillens than with the Injens.
