The Best Filtration

AEM has reinvented the Lifetime performance aftermarket air filter. AEM Dryflow BMW Air Filters are the first performance air filter that does not require filter oil to filter and trap dirt and contaminants, and delivers industry leading filtration and durability for BMW engines that is unmatched by our competitors.

AEM Dryflow BMW Air Filter eliminates the hassle of re-oiling after cleaning and has better filtration and dust trapping capabilities than any other performance aftermarket filter. Our unique non-woven polyester element filters out 98.6% of airborne dust in initial efficiency (99.4% cumulative efficiency), and filters down to ONE MICRON of particulate! For comparison, a human hair is about 100 microns thick. This improved efficiency translates into longer engine life by keeping more ring- and seal-eating dirt out of your engine, with no degradation in engine power compared to oiled air filters. It also means you won't have warranty issues at the dealership because you never have to worry about over-oiling the element and having the filter oil damage your vehicle sensors.

Plenty of Flow for Gas & Diesel BMW

AEM Dryflow BMW Air Filters flows almost as well when it is dirty as it does when it is clean, and flows over twice as much air than is required for large displacement engines in vehicle applications covered by BRUTE FORCE intakes. "Many of our competitors emphasize flow as a primary means of power production in intakes," stated Chief Engineer John Concialdi. "While flow is certainly an important part of the equation, we find that tuning the inlet to work with the harmonics of the engine produces the best power gains. We address flow in the sense that the BMW engine requires a given amount of flow, so we calculate our filter size to exceed this flow requirement to accommodate potential future engine modifications. This allows us to retain a high level of filtration efficiency and still exceed the flow requirements of an engine. Our filters will trap more dirt, and consequently extend the life of the rings and seals in your engine."
