Indeed you should always be skeptical when taking in manufacturer's claims. That being said, one of my favorite quotes is there are lies, damned lies, and statistics. Your application should be catered to your driving habits, wants, and needs, so some folks want prefer higher end horsepower, and some lower end torque. Interestingly enough there's a graph of a guy who did a CAI and scoop to draw in more air. I don't thing there's any ulterior motive for this guy to fabricate his results, unless of course he was paid by kokeln, which I doubt.

In conclusion, there's merit in a less restrictive airflow, but some folks have different preferences in the power bands and torque ranges.
