K&N Performance Powersports Oil Filter: Premium Engine Protection, Higher Oil Flow Rates, Compatible with All Oils, Optimized for Synthetic Oils, KN-401

fit like a glove was exactly what i needed. recommended to others

I don't have the Housing to use the filter

as always K N. filters have great quality, and since my bike is old, I got a real good price.

fit perfectly an come with the new gaskets

Worked. Could not find at auto parts or ins tore stock for one of our bikes. Cheaper than the dealer too, only had to wait a few days. So, plan a head.

Product was a perfect fit for my motorcycle. Brand new item shipped quickly in sealed box and came complete with new o-rings. Have ordered this iron the past and will order again when needed

perfect fit on a 2012 Kawasaki Ninja ex250j just have to frezze the bigger rubber first to fit right

Like always, when it comes to K&N all you can expect is the best quality products. Ordered both the air and oil filters for my 2010 Kawasaki Ninja 250r and can really say I am very pleased with my purchase. Oil filter comes with both o-rings needed and air filter even comes with the sealant cream. Products work great and I will always do business with them. And also thanks for the stickers :)

I've tried all the aftermarket oil filters for my Kawasaki ZRX1100 and found the KN-401 to be as good as the original Kawasaki unit.  There are two rubber oil seals in the cartridge metal body that need to fit tightly around the oil pick up bolt (Kawasaki calls this part an oil filter valve).  Only the K&N fits like the Kawasaki 16099-003 oil filter.   And another big plus is both O rings come with each K&N filter! Thanks K&N!

I decided to purchase this filter for the following reasons: Quality ... I have never had an issue with a K&N filter. I have with other box store brands. This filter comes with both gaskets which I prefer to change when installing a new filter. The large gasket is thicker than other brands so you don't have to over torque the plate bolt.
