Superior Flow Capabilities

Every DRYFLOW air filter is engineered to exceed the flow capacities of the engine it is required for. For example, a naturally aspirated 2.0L engine requires 253 CFM of flow. The filter we manufacture for a 2.0L Acura RSX Type-S delivers 565 CFM of flow when clean, which is 123% more than the engine requires. You get superior flow with DRYFLOW, in addition to the best filtration and excellent dust holding capacity. No other filter on the market delivers these three critical elements of filtration better than DRYFLOW.

Delivers Significantly More Flow Than Engines Require**

AEM’s approach to performance filtration is to achieve a balance between filtering efficiency and air flow. The result is maximum engine protection and performance. Our engineers design AEM air filters to significantly exceed the flow requirements of the engine for extended performance as the filter collects dirt.

Diesel engines require massive air flow. AEM has responded with a filter that dramatically exceeds that requirement without compromising filtering efficiency. For example, the AEM BFS-HD (PN 21-9221D) for the 2007 Dodge 6.7L Cummins Turbo Diesel exceeds the stock induction air flow by 84%.

Plenty of Flow for Gas and Diesel!

AEM’s DRYFLOW Synthetic filter 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. 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 engine requires a given amount of flow, so we calculate our filter size to exceed this flow requirement by a wide margin 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.

By designing our DRYFLOW filters to exceed the flow requirements for the size of the engine that we designed the intake for, it allows us to do two things. The first is that it allows you to add modifications that increase flow demand without exceeding the flow capabilities of the filter. Second, it extends the filter’s service cycle (you don’t have to clean it as often) because it can trap more dirt without sacrificing flow. Rest assured that we have taken flow into account for all of our intake designs and our DRYFLOW filters will deliver more than adequate flow for your vehicle.

Advanced Filration, the Incredible Dust Holding, and Excellent Flow

Going further between cleanings means less down time and more time for you to enjoy your ride. Additionally, this means less time spent in the lower efficiency part of the graph. Note that all of the competitor’s filters tested have much higher restrictions well before the AEM DRYFLOW filters do. Simply put, they get dirtier faster. Also demonstrated in this graph, is how the AEM DRYFLOW continues to flow with a much lower restriction for a longer period of time. That’s because the DRYFLOW filter’s higher dust holding capacity allows you to go longer before the flow falls off due to the restriction of the dirt captured in the media.

DRYFLOW holds more dirt and delivers the best air flow over the longest period of time when compared to the competitors we tested. Fewer cleanings means less down time.
