I am waiting for either K&N or Hennessey to produce a V6 CAI - I've messaged both with my interest:
K&N email
tech@knfilters.com; Hennessey
sales@hennesseyperformance.com - the more that inquire the sooner products will show up.
See this thread

As for the GM Air Box here's a link
http://www.gmpartsdirect.com, search on part # 92212304 - List price is $450, discounted price is $327.60. Looks more like a chrome cover and unsure of performance specs - it is not CAI as I understand.
