Which filter for dusty climate?

[snidley1]

I know there are a hundred threads about intakes for these trucks and I have searched until my eyes hurt, and I still can't make up my mind. I have looked at S&B's site and all there filter testing and also at aem and afe site's.

I had my heart set on a dry filter but then according to other's test's the oiled filters better, and I drive on a gravel road pretty often. Any sugeestions would be greatley appreciated



Thanks Todd

I had the same worries with my gasser (Ford Explorer). The K&N oiled filter (expensive) managed to cover my mass air sensor with crud within 2500 miles, leaving me high and dry on the SF Bay Bridge.



I buy the fram filters on sale now and change them as often as my socks when I am in the high country.

I would go with the stock filter if there is alot of dust. The stock air box is more restrictive than the filter so you wont see much difference in power.

I agree, and the stock filter has fairly deep pleats and a decent surface area.

What to you think about the afe pro guard 7?? I have heard that it filters better than others. You all make a good point though It might be best to stay with the stock filter. But what is everyone else running for an intake in dusty climates, and especially the ones that have oil test to prove it's working?? Thanks again for the input.

I live in a very dusty climate in west Texas and I use the afe pro-guard 7. My uoa come back great. It would be hard presses to find a more dusty enviroment than here. I've some pictures of dust I drove through here awhile back that had me worried to death. Pitted the hell out of my windshield.

Thanks for the info man. The pro guard 7 might be the way I go. The aem dry flow claims to fitler at the same level (99. 5%) with the fine dust analsys though?? Any thoughts??

I have been cautioned by the Cummins SW folks to stay away from Fram and K&N filters. They told me that the best filters for dusty environment are the stock filters as others have posted.

The stock filters do stop the dirt... ... ... ... . but if you don't change it in time when it gets bad it will collapse in the 3rd gens and you will have no filtered air

I saw that happen on a 06 5. 9. He got his turbo replaced under warranty because his servicing dealer never replaced the filter and never made mention of it needing done. The dirty air ruined the turbo

Snidley has a 6. 7, collapsing the stock air filter should be less of a concern than the problematic 5. 9 3rd gen filters that I am hearing about. From what I've been told, this problem has been addressed with the new 6. 7 filter and airbox combo. Can anyone confirm this?

In my 5. 9, I ran an oiled AFE ProGuard and it filtered fairly well, the oil analysis came back perfectly acceptable but this is in an average environment, no desert dust storms, just some gravel roads. I still think a quality stock filter would filter a bit better, but that is a gut feeling, I don't have first person analysis to back that up.

I personally run the pg7 in the stg2,and have had it all over the desert and Baja. The oil always test good,some people are paranoid or admit they won't take the time to service it correctly... ... ... ... ... ... ... . so there is always stock.





If the paper filters get wet,deep water fording or snow pack,they will still die an untimely death.

If you're looking for better air flow than stock, hte AFE Stage 2 w/ Pro Guard 7 or the S&B is the only way to go for the dust protection. The dry filters are good, but not nearly as good as the ones I mention above.

Another vote for the AFE PG7. The best OA numbers Ive had happened with a big AFE used BHAF style. Yes, its an oiled type, but never seemed to have a problem with oil getting in the intake tract like the k&n did. It flowed very well also. Not sure about these nano-filters yet. . Might be going back to an AFE.
