Which air filter ????
I bought a typhoon air intake around a year ago. It came with a cone filter. It looks like a K&N but I know it isnt one. I do not know how well it filters. My truck runs fine but I do not want to take any chances over the long run. The intake uses a 3inch diameter inlet on the filter. What brands should I consider. I've heard pros & cons on K&N, but i dont know about the rest of the filters available out there? Any help would be great. 
PS. I have a 4.6L F-150

How often do you service your cone filter? Everything I've read about oiled cotton/foam filters indicates they pass more small dirt particles than paper filters - not what you want on a street machine. Also, if you over-oil the filter you can foul the MAF sensor.

As Steina touched on, paper media filters out more small particles. The K&N and other cloth-oil media filters don't filter as well UNTIL they get dirty. A good filter should be one that has to be replaced more often, IMO. Means it is doing its job. Only thing is..I don't know if you can get a 3" paper cone filter...
...I don't think running the K&N or Typhoon or Paper filter is going to hurt you. As long as its got a filter on it, you should be fine. They all should filter well enough. Just don't overoil or clean the K&N too much. You can tear the cloth...which you then would lose filtering. I'm as anti-Fram as you can get, but I'm running a Fram air filter just cause....with paper how CAN they mess it up?

I wouldn't run a washable filter on the street for the reason I said earlier, but if you can get a K&N in the size you need then they're supposedly the best of that type. Get the recharge kit at the same time.

Run a quality paper filter. If you investigate K&N's own website they claim filtration rates between 97-99%. That seems pretty good until you compare the numbers to a good paper filter. My Donaldson paper filter has an efficiency of 99.8% when clean and 99.9% when a little dirty. That means that when clean the K&N lets in 15 times more dust and when a little dirty 10 times more dust. I don't think the compromise is worth it for placebo performance gains.

the info is very helpful, I just have one problem....there is no paper-cone that I know of, like Saurian said...(I could be wrong)...to fit a 3" end of a pipe....Should I revert back to my stock intake(the plastic) or buy the K&N for my aftermarket....I guess I'm torn on the issue(like everybody else) I want the performance, but I also want my engine healthy

If you can find a paper filter that will work then go with that. That is not my recommendation though but it sounds like you are concerned with running a K&N type filter and the peace of mind a paper will give you might be worth it.
I have run K&N's for 30+ years now and have never had a problem and recommend them. But they only need cleaned every 50k, re-oiled every 10k and you need to know how not to over oil. The only exception would be in a super charged or turbo charged application. At that point the biggest paper filter you can find is the best set up. You move way to much air in these applications.

won't particles this small burn
and what of the foam wrappers?
and i would not say its a plecebo performance gain but most cars don't need more air because that is not where the restriction is
now if your engie has been reworked and "fixed" it mat help

what are turbos spinning 10-20,000 rpm? anything could kill that
but i was thinking of this and will be building a air "box", thinking as big a flat panel as i can crm under a 78 bronco hood pulling air from the rad. support and turning the filter at a angle
now paper flows good when clean right?
how about a paper as secondary and k&n as a "pre filter"
or back to the question ..what of the k&n filter wraps? do these restrict to the point i may as well run paper

Paper flows fine when clean. The best way to maintain filtration and decrease restriction is to use a much larger paper filter. That's the problem with K&N filters, they sacrafice filtration for airflow. Look at their own numbers and compare it to even the cheapest paper filter. Take a look at the air filter I use on my open element intake: http://community.webshots.com/photo/...36219971hAOAqJ
I'm sure a smaller version of this filter is available with a 3" opening and would do the job. There's no question for me, 97-99% efficiency compared to 99.8-99.9%. Be creative and you can still have a filter that works well and decreases restriction.

Here is all the info you will need
to make up your mind. I see no gain to be had from any vehicle that is driven on the street from messing around with the intake or the filter. You will get more NOISE if you change stuff out but not more H/P.
I know all of us can read but can we understand? Check this out I think it is the best test that has been done from a truly unbiased testor.
