Air Filter for Gas Mileage?

Steved,
I wanted to try the Amsoil foam filter, but after two attempts (they did not fit), I went elsewhere. I did not like the gloppy oily mess antway and shuddered at the thought of having to clean and oil the thing. The vacuum gauge sounds interesting, how do you install it? Ilike the fact that the new Eaa does not have to be oiled and it still flows well, while (most importantly) filtering better than just about anything out there. Alas, no Eaa filter for my application.

The amsoil foams are nice, but mine is still sitting in a box on top of my workbench because I CAN'T GET IT CLEAN after 25k miles of use!!! It had a better fitment than even the Wix or OE Mopar filter, but what good is it if you cannot clean them??

The vacuum guage (the filterminder) is a factory piece on the dodge Cummins-equipped trucks...the filter change schedule is determined by how far the filterminder has pulled in. As for getting one...I think most big truck dealers have them...they require a hole to be drilled into the intake downstream of the filter (to show the filter becoming restricted)...http://www.filterminder.com/

As for the dirt, I wish I could post a picture of the filter I took out yesterday...you would see why the new dry filter would be useful for less than 10k in my application...

Steved,
See if you can figure out some way to rig up a prefilter, that would extend the filters life. It sounds like you have some vicious stuff floating around up there in PA.

I installed an EAA filter on my 2000 Excursion powerstroke about 7 months ago and can comment on a couple of things.

1. The filter clogs up more readily with the microfine dust that we have here. I have used the amsoil foam and the factory filter and neither of those two would clog up and restrict the flow like the EAA. Both of them would never get to the point where the indicator showed >25% restriction. The EAA showed >75% after about 15k miles. Even after blowing the dust off it still registered >25% restriction.

2. It is nearly impossible to blow out all the very find dust particles without risking damage to the filter.

The EaA filter, while apparently excellent at filtration, will not be "completely clean" after a routine clean-up. There will still be dirt left inside thus reducing air flow, compared to new. Perhaps this is also why Amsoil recommends replacing them after four years, as the filter itself will accumulate dirt overtime (despite cleaning), and reach its capacity? Pablo?

IOW, I don't believe the EaA is the best choice for maximum air flow, provided that efficiency/filtration is not a concern. I would pick-up a K&N from Amazon. Even if filtration was an issue, the poorer filtration from the K&N is unlikely to drastically reduce engine life to the point that one would care/notice.

If you have a turbo-diesel (newer Powerstroke, Duramax, Cummins), I'd look into the FRAM Air Hog (if your local stores have any). The Air Hog turbo-diesel models are supposed to have (8) layers of cotton media rather than (4) layers like a K&N. The urethane on the Hog is a lot harder/durable, too. I have one.

As long as your car meters the amount of air flowing past the throttle body to optimize the air/fuel mixture does it really matter what filter is used? Won't the car achieve the appropriate air/fuel mix regardless of which filter is used or how much air flows past the filter?

that's about the way i understand it, with the exception of WOT, when some filters would allow more air volume to pass
