Edit
I re-read. They claim 15hp gain. That's not too bad if it works.

Part of the draw of CAI's is the sound. They sound better, because they're less restrictive.
The stock intakes are also long tubes btw, but they're designed with different purpose in mind. Not everything on a 370z screams performance, as with all sports cars. There are also part and tuning decisions made with reliability, fuel economy, or of course cheapness in mind.
