Box containing the air filter for the 1961 to 1965 Giulietta Sprint and Spider models

This is a box containing the air filter for the 1961 to 1965 Giulietta Sprint and Spider models. The filter is made of metal and is in excellent condition. It is an original part from that era, professionally restored to impeccable condition.
The purpose of this filter was to house the paper or fiber filters and was installed on the carburetor. It filtered the air before it reached the carburetor, removing dust, insects, stones, and dirt, ensuring that the air entering the carburetor was as clean as possible for combustion. The filter box has been painted with high-temperature black semi-gloss paint.
The mechanism within the box could be removed in racing cars to increase combustion and allow more air in. In such cases, the air would still be filtered but through perforated trumpets.
