Full intake vs Drop in filter

Ok, been reading thru the forums for about a week or so. It seems that it's about a half an half about weather they work or not and if they filter out dust and stuff just as good as stock. Same with warrenty info about half and half. Now heres what I got and see if any one can help.
S &B OR BANKS for full intake.
or just get airaid for afe drop in filter.
I have banks dfp back exhaust
and edge programer. not really caring to much about COLD AIR cause so fair in 6000 miles the temp of air coming in has only been 2 degres hotter than outside when the truck is moving. For me I wanna get it for 2 main reasons edge recommands afermarket intake for more airflow, and the convence of not having to buy a new filter everytime cleaning is cheaper if the filter works like its supposed to.
As for warrenty I had K&N on my 01 mustang from day one 2 warrenty works one leaking tranny and other blown water pump which included to new heads and there was no problem. Im gonna call FMC to see what they say. I know kinda long but I don't like wasting money. Really Im leaning toward the drop in airaid filter then s&b then banks. Stock intake box is covered and plastic don't see it getting any cooler. well thx guys for any and all info.

No need to call FMC to see what they have to say. They have already given their response/opinion of aftermarket 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?
