Previous owner of my Sporty used them exclusively because he liked the Drag Specialties brand. Their oil filter is longer (holds more oil, and nicely chromed), but looking inside, the filter element did not go all the way to the end, so from a "media" area point of view, it is the same as the standard length filters. No spec on actual filtration, and you must use a three finger gripping wrench to remove (puts 3 dents into the side of that slick chrome cover) as there are no flutes on the end for a cap type wrench, too slippery to use anything else except the old "screwdriver in the side trick..."!
Standard Harley filter is very hard to beat...in either chrome or black...the poll numbers speak for themselves.
