Review on AEM 28 20480 Dryflow Air Filter by Johnny Wheat

These AEM dry flow filters are of the highest quality. I've bought many for different cars and they all work great. I used to buy a K&N but the oil on the filters gets sucked into the intake manifold and blows out the MAF sensor causing airflow problems. With a dry filter there are no problems with oil. It is less restrictive than traditional paper filters and will also save you money over time. They are very easy to clean, AEM says every 50,000 miles but I do it once a year. They make a special cleaner, but it can be expensive. Alternatively, you can buy a bottle of plain greens, spray on the filter, hose off until the soap is gone, then let it dry for a few hours, then put it back on.
