After trying to fully absorb the CAI results thread (
http://www.camaro5.com/forums/showthread.php?t=48202) my understanding is that the CAI by itself doesn't do all that much dollars per hp but instead opens the door to fully utilizing other mods down the line (long tubes, hi-flow exhaust, even forced induction). The stock intake will eventually become a restrictor plate once other things are added to the engine's "respiratory system". Now I could be totally off base with this but the CAI seems to be the first logical step in fully exploiting what the engine will eventually be capable of.
