I searched and was surprised to find nothing about this filter here. The main "feature" appears to be the pre-oiled paper media which Fram claims gives better dirt capture. They also feature a little heavier backing screen and a glue bead to keep the pleats from folding over. I recently purchase one as a replacement filter for an F150. I'm no fan of most Fram oil filters, but their air filters have generally appeared to be well constructed.
Has anyone seen any test data on the Tough Guard air filters?
