Air Horn
Three mounting screws
S&S recommends that air horns be used in racing applications only, as they do not provide the filtration required to protect the engine on a day-to-day basis. Any installation of an air horn on an S&S carb in place of an air cleaner requires an S&S carb support bracket, part #16-0471, to securely fasten the carb to the engine. This bracket is included in the air horn conversion kits.
S&S recommends that the bowl vent plug at the bottom of carb body be removed when air horn is installed, as air horn may obstruct bowl vent in air cleaner mounting surface of the carb body.
