Hey guys, I have the K&N Typhoon intake for my xA. The filter element needs a cleaning and I have decided to just upgrade to the new AEM dryflow filter. Any body know what size of the inlet I need to get? I think its gotta be either 2.75" or 3". Thanks fellas

 

movin' to 'A FI.....

 

moved to NA...

nothing to do with forced indution...

 

anyone have any idea? bump

 

The dry flow does not flow near as well as the K&N.

 

Just curious. What do you base that on? Have any links?

 

I'm curious as well. The reason why I am considering this AEM dryflow filter is because of the fact that it does not need to be oiled. Not to be lazy but I have seen first hand on how an over oiled filter can ruin a MAF (it happened to my buddy with a maxima). I just don't want to run that kind of risk with my car. I understand that if the filter were to be oiled properly, no problems would occur, however, this new AEM filter does seem to be a nice alternative.

 

it's alot smaller than 3 inch. either 2.75 or 2.5

 

K&N Typhoon is 2.5" od

 

thanks, I guess thats the one I'll be ordering.

 

The company I work for has a flow bench to test air filters. It is very true an over oiled filter can cause harm to a MAF, part of this has to do with the type of "Cotton" the other problem is the type of oil.
We test about every filter made. The AEM Filters well but flow poorly. The K&N Filters well, flows well, but does not hold the oil well. I can go on for days...but I can't type or spell so I will stop now.

 

So is the Green the best?

 

I would love to see hard data if you have it. I have seen published reports elsewhere, but can't remember the site. Maybe I can take a look around and see where it was.

Found it...

k*n/aem's seem to flow awesomely. and all aem's were k&n's for years. they just started making their own filters which are basically k&n copies

 

yes I'd definately like to see any hard data you have on this...

Rton20s: I believe that link is the one Weapon-R provided for the foam vs. cotton gauze filter comparison. They provided it to show that foam could perform better than cotton. Though I would say in some ways that comparison is incomplete.
As well it also does not show any dry type filters in that comparison.

You may be thinking of the filter shootout they had a while back where they compared
1 foam filters (hks)
1 dry metal filter (blitz)
1 dry-type filter (apexi)
1 oiled cotton gauze type filter (K&N)
the dry-type won in both filtration and flow
the cotton gauze came in second

I've seen those filter comparisons before as well. The dilemma for me is whether or not the AEM dryflow is a real good alternative to oil cotton gauze filters. My buddy with the maxima switched over the using the Apexi one after the oil from the K&N or AEM filter messed up the MAF. I understand that this may not happen to everyone. Perhaps I'm just worrying too much. But it would be nice to see how well the new AEM dryflow one performs. Its more affordable too @ $40 or so compared to the 80-90 bucks for just the Apexi filter itself.

 

Oiled filter elements are one of the best designs out there. I have been running them for a long time and have never had an over oiling problem. Just follow the instructions when you clean it and you should be fine.
