Convenient design.
The nut on the end makes fitting and more importantly removal so much easier. Had a few of these and no complaints.

Direct Harley replacement.
K&N quality. The nut on the filter casing makes removal very easy on my Harley as the filter housing is very close to the crankcase.

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.
