An intake system for an internal combustion engine of a motor vehicle which includes a first unfiltered air intake ( ) which is arranged at a location in the vehicle that is favorable for air intake, and a second unfiltered air intake ( ) which is arranged at a location in the vehicle that is protected against road spray and splashes of water. The two unfiltered air intakes ( ) each open into a common line ( ) which communicates with the internal combustion engine. In the first unfiltered air intake ( ) there is a moisture sensor ( ) which emits a signal when water enters the first unfiltered air intake ( ). This signal actuates a drive member which moves a flap between first and second switching positions. In the first switching position, the flap closes the second unfiltered air intake , so that no air can get into line from the second unfiltered air intake . In the second position, the flap closes the first unfiltered air intake , so that air gets into line exclusively through the second unfiltered air intake
