I run K&N in all my motorcycles
This is absolutely the best motorcycle oil filter out there. On a Harley, 5k miles between oil changes might be stretching it. Filters eventually get clogged even on engines that have no excessive wear problems. The more filter material the filter has the longer it will go before clogging. The ability to remove this filter with a standard socket is a nice plus.

Ease of removal
It’s helpful that it has the ability to use a socket on the front for removal verses trying to use the filter wrench

Good filters for the price. The nut on the end makes oil changes quick.

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.
