Take it from first hand experience. Do not get any of those. I too thought in theory that that type of intake would yeild the best results. I got mine before any testing had been done. Well it may have produced the most power if it were not for the massive amounts of heat soak. I had a Pipeline and it skyrocketed IAT's killing power. You can see how high the IAT's started to get with the Jannetty CAI test. I believe he tested 2 or all three of the ones on your list. The heat soak just gets worse and worse with those intakes the longer your engine is running and the pipe and IAT sensor doesn't cool off fast enough. The stock intake out performed the Pipeline after heat soak set in with my experience.

Take my advise and get what's proven. Vararam, New Era, and ADM race w/ scoop are going to get the best results. Even CAI inc with scoop or Halltech with scoop would be decent choices.
