An intake tube for an air intake system of a vehicle is provided. The air intake system is located upstream of an intake manifold and includes an intake enclosure and an air precleaner. The intake tube directs a flow of air from the intake enclosure to the air precleaner. The intake tube comprises a first end section, a second end section and a curved section. The first end section is connected to the intake enclosure and has a first longitudinal axis. An inner surface of the first end section defines a first section air passage. The second end section is connected to the air precleaner and has a second longitudinal axis. The inner surface of the second end section defines a second section air passage. The curved section is located between the first and second end sections. The curved section has a third longitudinal axis. An inner surface of the curved section defines a curved air passage. The curved section includes a compressed portion having a minor dimension and a major dimension. The major dimension is greater than the minor dimension so that the flow of air through the curved air passage has minimal separation which increases flow rate into the air precleaner.
