EZ removable
I like the hex nut on the end of the filter. It makes it easier to remove and install a filter on a Harley twin cam. K&N is a good filter but pricey. Some of these filter manufactures should make a generic filter with a nut welded on the end. All motorcycle spin-on filter are about the same micron filtration. You are paying for the name, pretty paint and the nut on a K&N. The best filter is the SS reusable cartridge type.

Super Filter
Habe den Filter für meine Harley Davidson Road Glide ,M8, 114CI gekauft und eingebaut. Funktioniert alles sauber und gut. Bin sehr zufrieden und verwende den Filter wieder. Sehr gut finde ich den Schskant Ansatz, dabei Harley der Ölfilter blöd verbaut ist, so kann man den Filter gut und leicht festziehen und lösen.
