the 6637 filter would fit without having to take the bottom support bracket and the tunnel thingy off..

Nice job!
That should help keep the dirt out well.

that is a size 11.5 redwing boot in the pic for reference

if i did my calculations right the other day, the 2790 filter has over 800sqft of media... i may be way off though....

the 6637 fits easy in a 7.3... the 2790, not so much... i had to move the battery forward in my 01 to get it to fit. my dually has two 6637 filters in it.. its kinda packed.. lol..

oh! i only use the donaldson filters too. its easier to remember the wix/napa numbers lol.... the donaldsons are hydrophobic.. the others might be but i know the donaldsons are...

bigr, when you get your 4" kit done, put one of these filters on and see how they compare..

- A vet' that's gone from a 7.3 to a 6.7, tryin to gather info & help out when I can. New to the 6.7 & PSA. Please excuse my potential FNG ways.

don't think that will happen. I prefer the multi media of the afe stuff. more choices and better filtration . and certainly easier on the eye.

it was more of a poke at ya anyway.. always so serious... better filtration? did afe come out with a different line of filters then the pro guard series?

Thank you! Thank you! Thank you!! I would love to have a No Limit intake but like you I'm done with AFE filters after dusting my 6.0. I'm in western Oklahoma and my truck sees as many miles of dirt as it does pavement. If a Donaldson will keep the throat clean on a tractor in the dustiest field conditions imaginable I'll damn sure trust it on my truck!

Are you back working on a 4" intake design again?

Buck1 · Feb 18, 2015

Looks good! I was pondering doing this just the other day, good work!

cbf9703 · Feb 18, 2015

Good write up, sounds like what I need when I upgrade to a 6.7!

lincolnlocker said:
this filter is way bigger filter media wise the 2790 has 10.5" diameter and the 6637 has a 8.5" inch diameter.. the 2790 is 11.88 inches long total hight including neck and the 6637 is 12.38 total hight including neck.. the pleats in the 2790 are 2.75" deep and the 6637 are 2" deep... i am guessing there is close to twice the filter media in the 2790.. the cfm rating, which i think means nothing, on the 6637 is 425 and has done just shy of 800hp on a 7.3 on swamps dyno, the cfm on the 2790 is 680... so a third more airflow...

Pretty sure it was just over 800 and over 1000 on the juice, but who's counting?
