Factory Air filter replacement?
The factory filter is VERY efficient. I am in the camp that you should replace it in-kind unless you go after some extreme power. In the early years, there were some air box "end cap" problems that resulted in a TSB coming out. The TSB stated to replace the end caps with new ones because the old ones warped. Besides this TSB, the factory filter is a proven performer and can last 80-100k miles.
When you buy from dieselfiltersonline, if you do so in bulk you can get a discount AND free shipping.
Here is some background that may help you decide:

If you want someone to say you can buy a cheap air filter, you may have to wait awhile.

Second - the Zoodad is a mod to cut a hole in the plastic behind your grill to allow air to more freely flow into your intake.
I had some links to the mod, but they are not working. You can do a search and find a BUNCH on it (even pics)
Lastly - here is the Ford stand on aftermarket air filters:
6.0L & 6.4L Power Stroke Diesel
Super Duty and Excursion Air Filtration
Q&A
Q: Don't all filters stop the same amount of contaminants from getting into the engine and turbo?
A: Absolutely not! The 6.0L and 6.4L OE filters, produced by Donaldson Company, Inc., stop 99.99% of contaminants the size of one micron or larger. Some aftermarket filters trap only 95%. What does this mean to an owner? Driven in the same conditions, a 95% filter would pass 50 grams of contaminant through to the engine that would be trapped by the OE filters! Even a 99.00% filter would pass 10 grams of contaminant. This could mean an early end to your engine or turbo.
Q: Won't aftermarket airbox modifications, which use a lower priced filter, save me money?
A: Don't be fooled by aftermarket tactics of comparing the cost of one filter because you also need to know how often you'll need to change filters. The 6.0L and 6.4L OE filters hold more than three pounds of dust, dirt and soot. The aftermarket kits tested by Donaldson Company, Inc. held about half this amount. And don't forget, if these aftermarket replacement filters are less than 99.99% efficient, they pass some contaminant through to the engine that the OE filter would have stopped!
Q: How frequently do the 6.0L and 6.4L OE air filters need to be changed?
A: Everybody's driving habits and environments are different.
Owners/Dealers should check the air filter restriction gauge (located on the upper housing of the air cleaner assembly) at each oil change interval to determine when the filter needs to be changed.
Some vehicles also have a dash light that will illuminate when the filter needs to be changed.
No replacement is necessary until the filter minder (or dash light) gives indication.
Q: My filter minder doesn't seem to move, so shouldn't I check or change the filter to be safe?
A: The filter minder is a gauge that starts registering only after the filter reaches a certain point of being filled. This is why owners do not see it consistently move (like a gas gauge). Rest assured, the filter minder works and there is no reason to check on the filter by removing the airbox cover, thereby increasing the risk of contaminants entering the air intake system. Remember, the 6.0L and 6.4L OE air filters hold more than three pounds of contaminant – so it will take some time to fill!
Q: I want maximum airflow through the system to provide more power. Don't some aftermarket filters provide more airflow than the 6.0L or 6.4L OE air filters?
A: Airflow should not be the determining factor in buying a filter. Think about it: would you ever operate without a filter in place even though you'd get maximum air flow? High airflow generally means the filter is less efficient at stopping contaminants, too. Owners should instead look for the combination of three factors: airflow, how small of contaminant the filter will stop, and how much contaminant the filter will hold. The 6.0L and 6.4L OE filtration systems provide a great combination and it comes standard on all Super Duty and Excursion trucks!
Q: If the 6.0L and 6.4L OE filtration systems are so effective and efficient, why would anybody pay to modify them?
A: Excellent question. It makes no sense to pay hard earned money to go backwards in technology – especially considering that such modifications may even put future warranty repairs in jeopardy. You invested in your 6.0L or 6.4L Power Stroke Diesel truck to provide years of dependable service. Ford engineered it with a great filtration. So just why would anyone pay to modify it?

This was the Broadcast Message that was released on the issue. I can not remember for sure if it ever turned into a TSB or not and I can not seem to find it if it did. Maybe bismic has the TSB number and I can check and see if it is still valid...
6.0 Air Cleaner Housing Appears Warped/Misaligned:
The appearance of a misaligned sealing surface between the air cleaner and mass air flow sensor is due to the design of the air induction system and the positioning of the clamps. The air cleaner should be sealed providing the gap is not greater than 16mm (5/8"). If the gap is greater than these measurments, attempt to reseat the air cleaner to the mass air flow sensor. If the gap is still too wide, replace the air filter element only.
