AEM DRYFLOW Synthetic filter for AEM Cold Air Intake and Short Ram intakes eliminates the hassle of re-oiling after cleaning, and is independently-tested to have better filtration and dust trapping capabilities than any other performance aftermarket filter on the market.

The AEM DRYFLOW Synthetic filter is cleanable AND retains the same great efficiency after cleaning. The DRY media will not blow through after cleaning like many oiled elements. Our media is so durable that it can withstand almost unlimited cleanings without degrading filtration efficiency, and its easy to clean! The DRYFLOW synthetic media is hydrophobic (resists water absorption), so there is less drying time, and since you never have to oil it, AEM DRYFLOW filter technology reduces cleaning time by approximately 90%. Because there is no oiling, the DRYFLOW Synthetic filter maintains virtually the same performance in efficiency and flow throughout its life. In testing by an independent laboratory (visit www.aempower.com for a pdf of the test results) you can compare the filtration efficiency between a new and cleaned AEM DRYFLOW Synthetic filter. Due to the superior fine-dust filtering efficiency of the DRYFLOW Synthetic filter, it may require slightly more cleaning intervals than oiled filters depending on your driving conditions.

Since AEM DRYFLOW Synthetic filter never needs oiling, it eliminates the possibility of voiding your vehicles warranty from over oiling. Anyone who has ever owned an oiled, cotton-gauze filter can tell you that over-oiling after cleaning is a possibility. Manufacturers have metering systems that apply the exact amount of oil necessary to new cotton-gauze filters, but squeeze and spray bottles commonly used to re-oil these filters after cleaning can lead to accidental over-oiling, which can damage a vehicles Mass Airflow Sensor (MAF) if the oil is pulled along the inlet onto the MAF.

AEM 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.
