A guy I met last week purchased a 2011 V6 and he got it tuned and dynoed with the stock airbox box on. He did a second dyno with no airbox, to let it breath more, and only gained 1 or 2 more HP, so he decided it was not worth the money to get a CAI.

I have used K&N on many cars over the years. I never noticed any improvment in power. On the negative side, if you get too much oil on one, it will mess up your mass airflow sensor right now. I have also read they don't filter all that well.
I changed out the K&N on my CAI to a filter sold be Amsoil. No oil to mess with, lasts 100,000 miles (clean every 25,000). They claim to flow better and filter better. Works for me.

There's actually more of a gain, it's all about how you test it. We saw as much as 8RWHP before/after just adding a CAI to an already tuned Mustang. 05-09 gained more than that, it's only been since 10' have they had 'decent' factory intakes that duct cold air, just not enough volume.
If all you're going to do was a cold air intake and tune, then the CAI might not be worth it from 2010+. If you had plans to add headers, or x-pipe w/ or w/out cats, pulleys, cams or any of those items I just mentioned - you'll notice that you actually lose alot more than 8 horsepower. The more air that you require, the more that the restriction will affect the vehicle's performance.
Someone with a 2010, long tubes, cams and delete plugs would lose as much as 15RWHP going back to a stock air intake on their GT.
2011 V6 could lose around the same if you've got aftermarket exhaust.
Again, it's all about how you test before/after, and what other modifications the cold air intake supports.
Once you start adding things, the cold air intake becomes a SUPPORTING modification, just like a bigger fuel pump, injectors, etc.
