Part Number: 21-204DK
Color: Red
Size: 3.50 in (88.90 mm)
UPC: 840879014858

Our unique non-woven polyester element is independently tested to filter out 98.6% of airborne fine dust in initial efficiency, with an industry leading cumulative efficiency of 99.4% (cumulative efficiency is the average for the test cycle).

The DRYFLOW also filters down to ONE MICRON of particulate! Our competitors claim that as the filter gets dirty, it filters more efficiently. While this is true, what they dont tell you is that their clean filter lets dirt through until it traps enough to become efficient! Get the best filtration the first time with AEM BRUTE FORCE intakes and the DRYFLOW Synthetic filter.

Eric Tcheordikian | August 1st, 2020
Filter works great, no damage in shipping. Loved the stickers that came with the part! My only hang ups are the wrong sized banding to hold the filter to my intake was sent in the box. I also didnít like that they changed the brand of the banding from the brand name AEM to what seemed to be a Cheap wholesale no name band. Maybe if the correct size band banding was sent my opinion would be different, but itís always nice to have brand name accessories to go with/ fit your brand name part.
Good product

Replaced the open funnel filter on my AEM V2 with this one. Fits perfect and sounds smoother a cold start.
