A bit thicker than the real deal
The filter is just a bit too thick. The stock bolts won't quite reach the threads for install. However, if you push with a bit of force near the bolt holes on the filter you can get the threads to start... and then cinch down on each of the stock star bolts in alternating pattern to work them into the threads. So...it will work...you just have to MacGyver it. The filter itself is of great quality and worth the savings for sure. Buy it.

01 road king
Great air filter element. Fitment was not correct. 01 v twin road king takes a different filter. Bolt holes don't line up. Had to drill the correct bolt holes and fill in the prior bolt holes.

Great
I recently painted my Harley Road King a blue and white and this air filter not only color matched my paint scheme but is a great filter to boot and won't break the bank either. I highly recommend these but not cause they match my color scheme but they are made with great materials and at the right price too
