I ordered a dryflow filter for my intake and got one of the new red one's. I believe k&n now owns AEM and it appears they are replacing the grey dryflow w/ this new red one red dryflow. They are also on k&n's site if you look, dry k&n . I'm a little worried about if these filters are as efficient as the old grey dryflow? I've emailed them to see what the deal is w/ the new one and if they have any data on it's filtration.
