My point is that K&N does not filter as well, and from some of the reports, after a short time, it actually doesn't provide as much flow as a stock filter (needs to be cleaned and re-oiled). So, for me, I am not sure I am willing to sacrifice filtering for no guaranteed increase. At least the last time I looked, K&N did not even advertise any HP increase.
I think I am entitled to my opinion, and I was simply trying to express a different opinion/information. If you don't like it, don't read it, but others may want to know. You can believe whatever you like and that is fine with me... Let me do the same..... I am always glad to read documented proof, if you have some to provide, post it....

I'd be more than glad to put a wager on dyno time with a stock intake vs a good aftermarket intake. I've seen first hand increases of 8-10 HP on vehicles only putting 160 HP to the wheels. Naturally, a drop in filter alone usually won't help this much.
If filtration is the main concern and you feel it outweighs any performance gains, then stick with the stocker if that's what you want. Many of the oiled foam type filters will actually improve over stock in the filtration department, but some will clog easily and restrict flow as well.

I just gotta say. I kept logs of gas mileage for my 98 w/4.6. I showed a 1 mpg increase when I switched to a K&N filter.
On my 01 w/5.4. the K&N air filter has yeilded no gains in mpg. I average 15.5mpg, mostly town driving.

The service manager at a local Ford dealership said, when asked about improving fuel mileage without voiding warranty, opening the airflow in front of the engine and behind the engine will increase fuel mileage. Changing the inake to a K&N filter and adding a cat-back exhaust will help.
He actually mentioned the K&N air filter. Of course, the K&N filter is the same one Ford sells as the "Ford Performance filter".
