Review on AEM 28 20129 Dryflow Air Filter by Josh Parson

Let me first say that after long hours of research, aem dryflow has the best performance rating for FINE mud at 99.4x the ISO rating. The information is hard to find, but it's there. It was necessary to have it for the dusty environment in the west while getting extra performance. It's not something you can feel, but it's there. You can see it in the fuel trim and the 0.4mpg increase if you're not a fool. However, I am disappointed with the quality of the silicone molds. As you can see from the photos there is nothing more to ask for but the filter material itself is the reason I bought this filter and it works so I took off a star because it does the job.
