As long as it is not coming with more dirt and oil like from famous K&N filters.
I do have the oval air filter in my truck, what from I know is FACTORY upgrade over standard one.
Does anyone provide comparison charts for air resistance and particle catching on those things?

Does yours look like this?



If so, that's a Ford AIS setup. Here's a marketing PDF of the AIS system:

Yup. Thanks for the link. I understand that my filter doesn't make lower resistance, but comparing to washable:
"5 x dust holding capacity
17x media area
400x more efficient at capturing harmful abrasive dust"
Make me wonder why anybody would like any of those cone filters, having such excellent choice from the factory?
I am not going to be popular between the aftermarket vendors, am I?

Your AIS is a higher flow rate filter than the stock filter. The AIS filter minder is calibrated to trip at less resistance than the stock filter minder.

but.. but ... that still is not saying if it makes lower resistance at the same flow?
Not that I would really care, but it is really too easy to fall for sale pitch, while the real technical data is suppressed.

Dang right...

Any motor is basically a big air pump...the fuel is fired to create the torque needed to spin the crank and to keep the pistons pumping the air to fire the fuel to spin the crank to keep the pistons pumping the air to fire the fuel...etc......more air, more fuel= more torque/hp...tell your teacher he's a douche...

I love my AIS. It does stop a heck of a lot of crud. But, the price is 4x the amount of a 6637 so...

Bottom line is any upgrade like the 6637 or AIS, AFE is superior to the stock set up for breathing and protection. The K&N drop in's are not very effective with the stock box because of sealing issues.

Amsoil offers the same kit but says it is not intented for modified trucks.
AMSOIL - 7.3L PowerStroke Air Induction System
I can get them for $250.00 plus shipping.
Another down side is that replacement filters are $91.00

Lower resistance at the same flow as what?

I had an AIS on my pickup for a couple of years, and I have a vacuum gauge. The AIS is lower restriction than the stock system and from what others have stated here the AIS with the fendersleeve is probably similar or lower restriction than the 6637. That's why I'm running the 6.0 filter, which is the same media but a larger filter and better design than the AIS.

I would be interested in that set up.
Got any pics?
How much work is involved to install it?

It's a lot of work to install, Pics are in my gallery. Here's the thread about the install:

Other guys that have done it since tell me it is a lot easier if you buy the 6.0 battery tray.

That looks like copy-cat of Ford system I have?
When I bought the truck 4 years ago -the small dealer told me that he paid $120 for the insert. He might pay premium buying it at stealer, but 100 bucks those days don't go too far. Than I estimate that even with occasional runs on dusty construction sites -I should get about 20 years from the insert I already have.
Thanks for the link.

One of those late Friday night posts
But what I get from it - your factory kit sucks the air from engine bay?
On my 99 model I do have factory cold air intake, but than I have the severe duty filter. Would you mind to post a picture or give better explanation how the air enters the filter on your model?

Both the Amsoil and Ford AIS are engineered and manufactured by Donaldson.

Meaning this is the same stuff sold under 2 different brands.
Talk about messing with customers heads.
Now we need members to start arguing "My Amsoil filter is better than yours AIS"
