Which Intake is Better?

In this case, it wouldn't be a Cold Air Intake ... biggest problem is companies make these and falsely market them as CAI's and they are not CAI's by definition. They are, however, less restrictive intakes and they do improve throttle response regardles of whether the air is hot or cold. IMHO, these are not worth paying the money they cost when you can buy a true CAI for about the same price, which DOES bring in outside air.
No rocket scientry that denser cold air produces more positive effects over hotter less dense air. I don't believe anyone would be foolish enough to argue that. My previous point is a true CAI reduces airflow restrictions and brings in the same air from outside the vehicle's engine compartment.
Even removing the restrictive intake baffles and changing to a less restrictive air filter to the stock intake is going to produce a positive effect, powerwise.
Here's a pretty good read on the subject:

As for the Aftermarket Intakes, I have yet to see proof that they actually provide any extra NEEDED air... Please provide some proof that the AM CAI of your choice provides extra air that is needed... These engines are air pumps, granted, but I am still waiting for any company to prove that the extra capacity is needed or will be used without other major modifications...

The point I was making was that there was no argument to be made if it was an open element in the engine compartment, that if someone did not understand that there was nothing that could be done to help them understand it was pulling in warmer air from the engine compartment... I think we are on the same page with that...

If you're just here to argue the point, then, what's yourt point? Stock intakes are generally hugely restrictive and most are highly under-tuned from the factory.
Results
After the dyno rollers stopped spinning, and the noise of the LS7 dissipated, the test results were analyzed. Although the Air-Charger coaxed out only an additional 2 peak horsepower, peak torque jumped by 12 lb-ft. Even better, there was as much as a 20hp and 46-lb-ft gain at 2,100 rpm. Below 3,100 rpm the average gains were just over 10 hp and 24 lb-ft. Overall, the average gains were 7 hp and 15 lb-ft.

There are plenty of dyno 'facts' all over the Internet. Many tuners who have completed back-to-back dyno runs with 1) a stock CAI on the first run and 2) only a CAI change on the 2nd run will tell you (even after a motor is heat-soaked when the CAI is installed for back-to-back-runs), CAI's will still yield positive results over stock.
I will grant you that older stock intakes were fairly restrictive but with flow technology and design getting better, not so much with our trucks...
The tune is a different story...

Clarification
OK ... so now you have defined exactly what you are debating. Are you saying 'our' trucks intake is highly advanced enough with today's technology, that, without any other modifications to our trucks, after market CAI's will not increase flow and produce additional horsepower or torque, due to better airflow into our engines? Please correct whatever part of my statement you feel is incorrect.
Since we both really need to stop jacking the OP's thread, once you clarify your true arguement (above), I will start another thread so you, I and anyone else can make comments, freely. You have every right in the world to speak your thoughts and to exercise that freedom. Please clarify and we'll beat this to death ... once again ... just like has been done on every forum I have ever been on. Deal?

MSG,

3. The OP's premise:
For the 1997-2008's the Gotts/DMV mod provided more than enough air, even at higher RPMs (again making A/M intakes a waste of money). For the 2009-10s removing the snorkel will add 7 hp (with a custom tune) at 5200 RPMs. Unless you're racing, who in the hell drives at 5200 RPMs? And (again) if you are, are you really trying to save gas?

I have a 2010 fx4 with a 5.4l. What intake do you guys think will do its job the best?
One aftermarket intakes are always better than stock. Plus I dont see the stock intake increasing my mpg or horsepower. So I refuse to believe the stock intake is better. What is you opinion on ur your stock intake?

I dont agree with the added HP only in the higher RPMS, that DEPENDS on the TUNER. Also your HP numbers are incorrect. Pherhaps if you actually looked at the Dyno results on VMP, PHP, And troyers websites you would see a much improved HP and TQ numbers from 1000 to 5000 RPM.

I was referring to the hp gains that can be directly attributed to removing the snorkel (intake mod). I was not referring to the gains that can be had with a programmer.
PHP is the ONLY tuner that has a SINGLE dyno plot with the snorkel removed. The plot (and the other 2009 dyno plots are in my gallery/album).
Please re-read my post.
