This is quality material. Not one thing on this is not solid or chincy. They have drilled required hole on mating surface for the super E carb that is needed like the stock ss super E aircleaner . No need to remove bottom Allen screw for "aftermarket" air cleaner. Bolt on and go. Polishes back up easily with neverdull too. So stoked on this cleaner. Gives my schovel a cleaned up non bulky look with a functional included filter. I also pick up more chic's with this air cleaner. The stock ss cleaner was bringing me wore out old haggered ladies. My Benchmark brings all the sweet newer ho's!
