Review on 🏍️ K&N Motorcycle Oil Filter KN-401 - High Performance, Synthetic/Conventional Oil Compatible, Premium Quality - Fits Kawasaki Vehicles (Select Models), Color: Black by Robert Toomey

O-rings were too thick. I had to work very hard to get the bottom plate over the o-ring on the stem and the large plate was too thick and didn't fit properly. I poured out about half a liter of oil and had to completely change the oil with matching o-rings. In the garage it didn't leak, but under pressure with the engine running. I used to use K&N with no problems but they gave up on this one.
