Great Filter and Great Price
Only filters I use. I’ve got a Street Glide and a Night Train and both have the trusted K&N brand filters. The built in nut on the filter makes it super easy to add and remove.

Top Notch!
Probably the best H-D filter out there! Top quality! I use the black and write the date and mileage on it with a silver sharpie.

Good Filtration And Never Had An Issue
Long time user of K&N filters and yet to have any issue. I go through 4-6 filters a year and they have been consistent throughout the years. The addition of the bolt head has made removing the filter a lot easier since on my Road Glide it's tucked back in there a ways (unless you over-tightened it last filter change!).I feel they have always been a good value and one I trust.
