An air intake, especially for internal combustion engines with a V-shaped cylinder arrangement, which is composed of two units (16a, 16b). From the two units (16a, 16b) extend the intake ducts (19a, 19b), each associated with one cylinder bank (11) of the internal combustion engine. By dividing the air intake device into two units (16a, 16b), the unit (16a) can be mounted first on the internal combustion engine, a free space (20) for the mounting tool being necessary. Then the unit (16b) is placed and bolted on, the air intake ducts (19b) being able to run through the free space (20) in the hatched area (23), since the unit (16a) is already installed. The advantage of this air intake tube configuration is a substantially greater geometric freedom of design.
