An air inlet arrangement is provided for a work vehicle that has an auxiliary bay external to the engine compartment. The auxiliary bay can have a bay cover in part forming a step panel for the operator. The auxiliary bay contains an air cleaner coupled to an air inlet via air ducting that extends through the engine compartment. In the case of work vehicles having an aftertreatment device within the engine compartment for example, the air duct extends through the engine compartment between a side wall of the engine cover and the engine and/or the aftertreatment device. The air duct can at least in part be formed as a unitary part of the engine cover with multiple tube segments of differing cross-sections. At least the segment passing between the engine cover and the aftertreatment device can be oblong with a major axis essentially parallel to the engine cover side wall.
