K&N, FRAM Air Hog, or Amsoil Foam?

[RedWolf4000]

I have been thinking of buying a cotton or foam filter. I extend my oil drains to 7500 miles with m1 and i also wish to make other basic maintanance things have extended life, hence a extended life air filter.

Which is the best? I hear the FRAM Air Hog is thicker then the K&N so thats a plus for me because i am mainly concerned about filtration. (should i stick with paper then?)

I have heard many say oiled cotton filters work better, and some say they work worse then paper. Which is best for extended drains?? Does cotton keep my intake clean??

i think your best bet is to go to the oil analysis section and check out what air filter they run and how it does in the "SI" area.

you will get mixed opinions trust me on that...yet i think paper is a good long lasting thing...

The high quality paper filters are the ones to use IMO.

There was an air filter study done over at the dieselplace.com on Duramax airfilters. Bottom line was the best filter was the OEM paper.

Thanks guys, now im sure that paper filters are the best, and are worth changing every year.

If you do want an oiled cotton air filter, The GREEN FILTER sounds like the best one. I'm thinking of getting one for the track and using a paper one for everyday driving.

Well, when in autozone today, buying some replacment tail light bulbs for my trailer, i took a look at all the cotton filters offered, K&N and AIR HOG. Although they are sealed in clear plastic wrap they were easy to inspect. Held them both up to the light, K&N let a little more light in. Anyway, for $27 at my autozone, i bought the AIR HOG on a whim.

Let me just tell you, when installing this puppy, it sat and sealed (visually) perfectly. Instead of the sides of the pleats being visable, they are covered by a long thick rubber lip that extends down from the seal on the top. After installing it and driving home i did not notice anything odd, it sounded fine. When i gun the car, i THINK it feels a bit zippier but everyone THINKS that when putting a cotton filter in. Fact is i was really happy with the construction quality of the AIR HOG after handling both pieces.

I will track my MPG again, with this filter see if it changes. But, because i drive a 5-speed and its not consistant on shift points and so on, it will be very hard to tell if i gain anything.

Another big selling point with the Air Hog is that the cotton actually changes color when its dirty, and when cleaned and re-oiled it returns to its FRAM ORANGE color, i thought that was pretty cool.

Anyway, it cost a bit less then the K&N and it is visably thicker, and it is of high quality.

I had a K&N panel type filter on my Jeep for a while and it seemed to be to small and did not seal well. For paper I like the O'Reilly house brand/Puratator filters.
