An under-hood mounting configuration for a work vehicle may generally include an air intake component positioned upstream of an engine of the work vehicle. The air intake component may include a wall having an exterior surface and an interior surface. The wall may define a cooling port extending between the exterior surface and the interior surface. In addition, the under-hood mounting configuration may include a control unit having a housing defining an upper surface and a lower surface opposite the upper surface. The housing may be mounted to the wall along the exterior surface such that the housing is positioned directly over at least a portion of the cooling port. When the airflow is directed through the air intake component, a portion of the airflow may flow through the cooling port and may be directed towards the lower surface of the housing.

The system of claim 9, wherein the wall forms part of the filter assembly of the air intake system. 12. The system of claim 9, wherein the wall forms part of the at least one aspiration component of the air intake system. 13. The system of claim 9, wherein the housing is mounted to the wall such that the housing covers the entire cooling port. 14. The system of claim 9, wherein the emission sensor comprises a NOx sensor. 15. The system of claim 9, wherein the emission sensor is in flow communication with the exhaust flow directed through an exhaust conduit extending between the engine and a DOC system of the work vehicle. 16. The system of claim 9, wherein the airflow flowing through the cooling port contacts the lower surface of the housing in order to provide convective cooling for the control unit. 17. The system of claim 12, wherein the at least one aspiration component comprises an aspiration conduit coupled to a scavenge port of the filter assembly and an aspiration scoop coupled to the aspiration conduit. 18. The system of claim 17, further comprising a fan and a fan shroud at least partially surrounding the fan, the aspiration scoop extending through a portion of the fan shroud.
