Top Quality Filters ! The nut is for removal ONLY !
I have been using K&N filters for my motorcycles for over 40 years. They have never let me down. Pro Tip: the 17mm nut on the filter is for REMOVAL ONLY ! Do not use the nut to tighten the filter. If I can't get it tight enough by hand I use a strap wrench on my Harley to tighten the filter.

As good as OEM filters
Used on 2011 Road King, prefer not to pay dealership rip off prices. This filter is as good or better than OEM from independent studies.
