AEM EXTREMELY abused its' new Synthetic DRYFLOW Air Filter with brake cleaner, window cleaner, industrial cleaner, bleach, Honda Brite, carb cleaner, weld prep and topped it off by blowing the filter out from the inside with 125psi directed air stream... Then sent it back for independent testing to see how efficient the filter would be. Test results showed that the filter's initial efficiency was 98.17% which is only .18 difference from the initial efficiency of a BRAND NEW filter!!
