Great oil filters that are so easy to fit and replace because of the end nut.
I always use K&N oil filters on my Kawasaki Ninja1000SX, Quality is excellent and with the end nut theyโre so easy to fit to the correct tightness and remove when replacing without needing a oil filter wrench. Also Iโve never had issues with air locks on K&N oil filters causing low oil pressure and then the need to burp the oil filter, an issue Iโve experienced with Kawasaki branded filters in the past. Highly recommended!

Good fit good price with nut attachment
Very good filter the fit is good (Make sure it will fit with the nut attachment it might come out to far if your bikes filter is in the front of engine hitting the downpipes.) the thread goes on nice and smooth. Great value for the money. The K&N filter has a white area on it which you can write on with permanent marker Mileage and date of oil change saves having to keep it written on paper some where. Had no issues since fitted, haven't removed yet as it is not due for oil change yet, but can't see any issues removing it having the nut attachment. I think the filter is a good price on Amazon and next day delivery can' beat it in my opinion. I would recommend this K&N filter good products. Hope this Helps

K&N Quality
Great quality oil filter! Iโve used K&N products before, and this one didnโt disappoint. It feels solid, fits perfectly, and works exactly as expected. My bike runs smoothly and I trust the filtration performance. I would absolutely buy this filter again.

Easy fit oil filter body.
fits my Ninja 9 perfectly. This one has a 17mm bolt head on the top to help with screwing into the engine sump. Went in perfectly whilst being careful not to scratch the paint surface with my spanners.

Z650rs
Fits z650rs perfectly BUT be aware that the nut is for removal only and people have broken the weld unwittingly torquing the filter on
