K&n excellence, like always.
If you actually love your cars (or in this case, motorcycles) and/or plan on keeping It for a while (and not simply beating on it then selling it...) than you NEED a K&n oil filter. People always buy these nice full synthetic oils for their vehicles, but skimp and buy a cheap-o oil filter, thinking they don't need a high end oil filter... But they do. This filter was obviously high quality, and easy to install. It comes with 2 little O-rings, one large and one small. Note** when you take off the old oil filter, make SURE that you see where these new rings go! In my case, on a 2011 Kawasaki Ninja 250, I only found a spot for the large o-ring, never found a small one? So I just saved it for future use. I assume that this filter fits on many motorcycles, so they probably included both o-rings to accommodate those that use them. Nonetheless, I feel that this should have been stated somewhere, as it would have saved me some time. Overall, this is a very high quality filter, and I have no outstanding complaints. It's priced very well, and (frankly) gives me peace of mind about how well my bike's inner workings are being protected.

Quality and performance you trust
I've been using K&N filters on most of my stuff without issue for years. I'll use cheapos for break-in and testing, but I always switch to a premium filter for daily use. These always fit perfectly and the bike runs great. Probably overkill, but it's cheap insurance.

About the O-ring issues..
I have a 2003 Ninja250R, and I have never had a problem with the KN-401 o-rings. I have used this exact filter kit 3 times, and when I bought it on amazon for the first time I was worried because of the reviews. I can safely say that on the Ninja 250R (pre 2008) that this filter and O-rings fit snug and fine, never had an issue getting the o-rings in and never had a problem with them leaking. Maybe it's different for other bikes but for mine this does the job great.

Good price. I like having them delivered so I don’t have to go to a auto parts store and try to find them.
