Abstract
An improved air filter has a plurality of tubular or cylindrical openings extending through a lower plate which are aligned with the venturis in a carburetor. The venturis in the carburetor draw in air through the filter. The openings in the air filter eliminate the turbulence or efficiency losses typically resulting from the use of an air filter. The openings are constructed to guide the air flow thus increasing the air volume through the carburetor. The inventive air filter configuration results in a seven to eight percent decrease in air flow over free air flow through the carburetor. Prior art air filters result in decreases on the order of twenty percent. In the use of carburetors for racing applications, the addition of approximately a twelve percent increase in air flow with the inventive air filter configuration provides enormous unexpected benefits. While it is necessary that the air be filtered on the way to a carburetor, it is also desirable to decrease the restriction in the air flow to the extent possible. The inventive air filter configuration eliminates the restriction to air flow reaching the carburetor, and provides valuable benefits which are particularly useful in racing applications.
