Better filter than what was available at Harley or an auto part store.
Perfect fit for my 17' ultra limited, has the nut on the filter for easy removal and install. Chrome looks good and was a better value that any auto part store. The o-ring seal seems pretty flexible as well.

Top-Notch Performance and Easy to Install
The K&N KN-171C Motorcycle Oil Filter is a fantastic upgrade. You can tell right away it’s built with quality in mind. It works perfectly with both synthetic and conventional oils, and I’ve had zero issues with performance. The wrench-off nut is a game changer—it makes installation and removal incredibly easy, especially compared to standard filters. No slipping or struggling, which saves time and hassle. Fitment was spot-on for my bike, and it feels secure and reliable once installed. K&N definitely delivers on durability and performance with this one. Overall, a high-quality oil filter that’s easy to use and built to last. Highly recommend!

Quality part
Hard to say much about it except K&N filters are well-made and fit properly. I love the nut on the end to help get it off if needed. These are a quality part.

Having the nut on the end… brilliant. Makes changing the filter a ten second job unlike the ones that need a strap wrench
