Review on Arlen Ness 18 321 Sucker Filter by Corey Krull

As advertised, the solution to the "HD air filter oil, valve cover ventilation problem", also looks good, small, inconspicuous, at a reasonable price! Installation, about an hour. (more time for OEM removal than installation) delivery time approx. 4 days, used with HD SE mufflers, very satisfied! You can add a "sock" or OEM cover if you plan to ride in all weather conditions as the filter is exposed. Invoice.
