if you've got about $60 laying around to spend do it. Its not a huge improvement but it is noticable. I am getting better gas mileage too. It helps reinforce your power, but not much gain. It is a high flow filter that traps more dirt and runs your engine more efficently. I'm glad I got mine. It really helps downshifting on hills and so on. Its guaranteed a million miles too.

These filters can be cleaned and used over and over again. They are thinner and like mentioned above allow less restrictions than OEM. If you get one make sure you buy the cleaning kit to go with it. When it is dirty..you simply spray with the soap, let sit a few minutes, then clean with hot water. let it dry good, then reapply oil ( in spray can) which is red in color allowing you to easily see your coverage during application.

Read the "Air Filter Test Results" & view the photos & pressure drop numbers, at the following link & come to your own conclusions. While not scientific, it is IMHO interesting and telling. http://bobistheoilguy.com/airfilter/airtest1.htm About 2 years ago, on the Cummings site warranty info page, it was noted that warranty claims for excessive piston & cylinder wall scuffing from using oiled gause or foam type air filtration would be cause for claim denial. Think I'll just stick to the specified filter material & change intervial on my 4.0L.

Had one, went back to the paper filter, on my 4.0L 2001 After reading the info on the above mentioned site, it made up my mind, the idea of my engine lasting over two hundred K miles appeals to me with the price of these trucks. I want this one to last until they get the mileage up to where it is economical to drive. Too much silicone in the oil with any of these oiled gauze and foam filters. Paper does a better job IMO.

I also put a K&N filter in on my 03 4.0l edge, I guess it did it job, but after reading about the dirt and what not that can potentially pass through the filter I put a paper filter back in. I figured everyone is for them or against them..50-50 type deal . I might as well be safe than sorry ,especially after buying the truck brand new. I would like to use the K&N filter, but it doesn't give that warm fuzzy feeling.

The K&N claims are all hype!! And if someone claims to have seen a difference, it's due to the "placebo effect".
Check out this URL for a truely independent dyno test of a K&N air filter:

Stay with the OEM paper filter, and change it regularly......

Here's a link to another air filter test.

In this test, the dust ranges in size from less than 2.5 microns to greter than 80 microns, but from what I read, it does not show what size of particles are being filtered out. (FYI, human hair=60-75 microns, anything under 35 microns is not visible to the human eye) To me it seems that the better filtering filters probably filter out the even the smallest of partices, which isn't bad, but how necessary is it to filter sub 2.5 micron particles. I would like to see results of testing dust of more limited ranges, to see how small of particles each filter is cabable of filtering. In this test the K&N filtered 96.8% of dust. If that 3.2% that is making it through is only 2.5 microns, then it's really not as big of an issue as it might seem.
