🏍️ K&N Motorcycle Oil Filter KN-177: High Performance, Premium, Synthetic/Conventional Oils, Fits Select Buell Vehicles, Black Review

Good quality filter but will not fit 2003 XB9R lower fairing bracket. Nut welded to filter enters lower fairing bracket.

KNN filters are my favorite filters. My wife's SUV, my jeep, RV and generator, lawn mower, backup generator and now my motorcycle. I like that they are easy to remove and replace.

Needed a replacement oil filter for the bike I bought. Always rely on K&N to deliver quality products, so I replaced the base filter with K&N. I know I don't have to worry about it doing its job and expect it to do plenty of miles and keep the engine in tip-top shape.

In my opinion the best oil filter money can buy. I love that they have a wrench and if you've ever seen an oil filter without one and it wouldn't come loose, you'll really appreciate a K&N oil filter. Also, they are simply better than FRAM or other brands.

I've been using this KN filter on my Buell XB12 for over 10 years. Maybe there are cheaper filters, but I haven't found the best quality. The main feature for me is the non-welded end, pre-drilled for the safety wire. In addition, the nut makes it easy to remove the filter with just a wrench.

Perfect for my 2002 Buell Blast. I like the black with minimal white markings so it doesn't stand out (because it literally sticks out on the bike). I also like the protrusion on the bottom that allows you to use a wrench to install/remove (or a torque wrench if you're the "by the book" type of person). This is a big improvement over an oil filter or strap wrench. K&N has always met my expectations.

I've been using K&N oil filters on my cars and motorcycles for a while now. It seems like a quality product and I love being able to use a wrench or socket when removing it. I just have to be careful not to overtighten them. I've never had a problem removing the K&N filter like some other brands and have never had a single leak, so I'll pay a few bucks more for the peace of mind and ease of installation and removal.

Perfect fit for my 2003 Buell Lightning XB9S. As with any filter, it is best to change it at every oil change. It's hard to say much about the internal quality without cutting it in half, but it seems good enough. As others have said, the 17mm nut is a sleeve - it makes removing the filter a lot easier. Be sure to fill the filter with oil before installing it to prevent the engine from running without oil for several moments after an oil change.

I have used KN-177 on both Buell XB12S 07 and 08. When I got the bike, 08 had KN-177. KN-177 is slightly shorter than the filter he replaced with 07 (not sure what brand he replaced but most likely HD as that is the brand of oil the previous owner used). I cannot confirm the effectiveness of this filter in terms of whether its filtering is better or worse, or whether it is more or less restrictive compared to other filters. But I can confirm that it's made of thicker steel than most filters…
