Great filter for my harley
Never an issue, easy on and off with no leaking

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.

Good quality, as always with K&N. Love the 'nut' end for removal.
Been using K&N filters on multiple vehicles for years now, and always happy with 'em. I'll never buy another filter without the 'nut' end for removal.

fit perfectly
2014 dina that I have this perfectly worked great, it’s a little smaller than the stock one, but it worked fine. Took a little less oil.

All oil filter should have that not on the end.
KNN oil filter filters are the only ones I use. I love the fact that you can just use a regular socket to take it off. I’ve never had a problem with them leaking, and they seem to be filtering my oil very efficiently. I believe they make a quality oil filter. It may cost a couple dollars more but I think it’s worth it.

Great K&N product, crappy Amazon packing
K&N oil filters have always been my go to oil filters. Great quality products. As good as or even better than OEM. Unfortunately, this particular filter arrived in a plastic Amazon envelope! With NO packing or protection what so ever!. So, of course, the K&N oil filter box looked like absolute crap! All the corners are mashed in as though someone purposely kicked it up and down my street! Very disappointing that Amazon has become too cheap to ship it in a BOX! luckily, the filter survived without any damage, Amazing!. I loved the discounted price on Amazon, but I think I’ll go back to buying them at my local retailer to avoid this disappointment in the future.

Lo compré para una Harley Davidson y encaja perfecto, el torillo para aflojar es un gran acierto para hacer el cambio ya que a veces se queda pegado y no sale, lo recomiendo.

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.
