Abstract
An air intake filter for the internal combustion engine of a motor vehicle in which a substantially cylindrical housing contains an annular filter insert through which the air flows radially from the outside to the inside. At one end of the housing an end opening of the filter insert sealingly engages a tubular projection which communicates with the clean air outlet so that the filter insert is centered within the housing. At its opposite end, the filter insert is closed by a cover and is provided with fastening elements which engage in the junction between the housing and the cover, so that the fastening of the cover to the housing simultaneously serves to axially and radially secure the filter insert in place. Alternatively, the cylindrical housing may be formed of two, semicylindrical half-shells, and the filter insert may be provided with an annular bead which mates with a corresponding indentation in the housing to assure proper installation of the filter insert.
