Abstract: A filtered carburetor cover is temporarily and removably secured to the carburetor throat of a motor vehicle internal combustion engine, for precluding passage of significant amounts of dirt, dust, and foreign matter into the engine intake system while the engine is run. The cover is preferably no larger, or not significantly larger, than the lateral dimensions of the carburetor to which it is secured. The relatively small size of the present carburetor cover allows complete access to the external adjustable components of the carburetor with the cover installed. The cover comprises a generally cylindrical housing having impermeable sides and a porous top, with one or more filtering elements in the top.
