Best universal cone filter

[Champ_white_FL5]

Hey everyone,

I recently bought an aftermarket intake for my Civic Type R for those sweet turbo noises. The intake I bought comes with a privately labeled green filter which is an oiled cotton gauze media. Because of this, I'm looking to replace it with either an AEM Dryflow or an AFE Pro Dry S for their superior filtration abilities as I live in a dusty environment.

I was able to find a study by SWRI comparing these filters but the study was done in 2007 I believe and I think the AEM Dryflow's filter media has been updated since then, so I'm not sure how much weight that study holds today.

Does anyone have experience with the AEM Dryflow or AFE Pro Dry s that they can share? And would you recommend it for a dusty environment?

my house is full of "boob" lights (real term)

but I've never seen a "boob" filter

Another option for a foam filter

I used an AFE on my 911. Well built filter and it was a dual cone for more surface area.

This test might be helpful:

AEM's air filter business was sold to K&N. The filters may have changed since that SWRI study was done. K&N has published ISO test results for some of the K&N filters as well as some AEM Dryflow filters, though I don't see them posted on their websites anymore.

Here's an example of a test report for an AEM Dryflow. Efficiency is 98.3% initial, 99.0% average. Considering that they're using coarse test dust, this isn't nearly as good as what the SWRI study showed, but it seems to be a lot better than a typical K&N, and close enough to the efficiency of a typical paper filter. For instance, the test report for the K&N filter that fits my car shows an efficiency of only 96.9% initial and 98.1% average.

Thank you very much for sharing this! Looks like the new red media doesn't perform as well as the old grey media that was used in the SWRI test.

I kinda figured the new dryflows don't filter very well as when I've held one up to the light in the past you can see tiny pinholes in the media. I also noticed some dust buildup in the intake tract of a friend's car using a newer dryflow.

On the other hand, my girlfriend has an AFE pro dry s and when holding that filter to the light, there are no holes and the media is very dense and fluffy almost like a paper filter. I've also checked her intake tract and haven't found any noticeable dust buildup.

I guess it's safe to say the old SWRI test doesn't hold up anymore and I will be going with an AFE pro dry s.

Thanks again for posting!

That's a good looking setup! Have you looked in your intake tube to see if there is any dust buildup? I'm most likely going with an AFE pro dry s. The media looks a lot more sense than an AEM dryflow

Sold the car but the intake was always clean.

I would love to run a cone filter on my Ion Redline, so I can hear that supercharger whine again, but I travel lot's of dirt roads in the summer so I switched back to the OEM paper filter. Was always worried that I would end up wiping the lobes of my S/C running a K n N oiled cone filter.....

I think an AEM dryflow or AFE pro dry s will be sufficient. I know some OEMs use AEM dryflows for factory performance parts. Mazdaspeed, nismo, and I think Mopar use AEM dryflows for their factory performance parts.

That sounds reasonable, thanks!
