Exactly! But the original question leans towards airflow and/or performance. So at least we both agree that the K&N with it's less restrictive setup flows better. The benefit here is a quality re-usable filter...
That reminds me. K&N now offers a PreCharger for most of it's popular filters.
What is a K&N PreCharger?
The K&N PreCharger is a specially designed filter wrap made to extend the service interval of your K&N Filtercharger when used in very dusty conditions. They are made from durable polyester material containing a uniform weave. The PreCharger will stop small dirt particles with minimal restriction to the airflow of the filter. The PreCharger is designed to be run dry and can be cleaned with K&N Filter Cleaner. The PreCharger is custom made to fit each application. Double stitched elastic openings assure that the PreCharger will stay in place. The PreChargers are available in a variety of colors, all with a silk-screened K&N PreCharger logo.

I have K&Ns on all my other vehicles. They are normally aspirated engines and airflow at the intake has more of an effect than on a turbocharged engine. The stock filter on the 6.0 is a very serviceable filter for its duty. I for one will stick with the stock until someone can show me independent information that any other filter will give the same or better filtration with same or better airflow.

What about less power due to the restrictive housing? How you going to explain that???If you use the K&N filter/Generation II FIPK kit and the precharger...you'd get excellent filtration and better flow...Right??? Plus a filter that will service the 6.0L engine for life. Na...don't want that...lets pay $90-100 every time the filter needs replacing. That works better too.
Conclusion: Let's reduce air flow and stick with stock setup (both filter and housing). More air in doesn't apply here!
FYI...I am not disputing the fact that the stock filter is 99.9% effective. Just that the K&N filter w/precharger offers great filtration and flows better.

Do you think K&N coming out with the "precharger" is their
way of admitting the standard K&N filter DOES NOT filter well???????

As to your "independent" tests, not sure what to say about that. Only that if K&N is making false claims regarding their products...well maybe I should call my attorney and file a class action suite? Care to join in?

If FORD would remove the restrictive housing and use the Donaldson brand filter with a Generation II FIPK type kit...then this thread would not be needed.

k&n filter not available
I called K & N filter company last week and asked them if a filter was available for the 6.0 diesel ford truck. I was told that it was not available and would never be available for the 6.0.
So I really don't know what all this nonsense about k & N filters are from. Someone needs to get there stories straight. Obviously someone had not done their homework.
Also, I read the forums a lot and have yet to find anyone that is completely satisfied with their Ford Truck (diesel). Why buy one if you can't appreciate them.. I love my 6.0 Ford diesel and yes, mine is a 2003 model.
