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.
