The claims made are great, however I'm skeptical, seems like a miracle in a bottle kinda thing. Any thoughts?

Depends upon your perspective. Do they actually add power? The answer is yes, but not very much and only in RPM ranges the engine rarely sees.

^^^ This.

Opening up the intake might find a few ponies especially above 6k rpm. How much time will you actually spend above 6k rpm? Will it deliver faster lap times or only inflated peak dyno numbers? How much is that worth to you?
