The air guide includes an air guide body having a plurality of surfaces and an air passage opening arranged between adjacent surfaces of the air guide body, a guide surface which corresponds to the opening and configured to act on airflow through the air passage opening; and an end region which extends from the guide surface and which is spaced from and extends in a plane which is substantially parallel to a plane of the surface of the air guide body. The guide surface begins at a first edge of the air passage opening and the end region ends at the opposite edge of the opening, and the end region does not overlap with an adjacent surface that continues at the opposite edge of the air passage opening. ## Claims ### Claim 1 Air guide for a fan cowling of a motor vehicle, the fan cowling being arranged downstream of a heat exchanger in a direction of airflow, the air guide comprising: an air guide body having a plurality of surfaces and an air passage opening arranged between adjacent surfaces of the air guide body; a guide surface which corresponds to the opening and configured to act on airflow through the air passage opening; and an end region which extends from the guide surface and which is spaced from and extends in a plane which is substantially parallel to a plane of the surface of the air guide body, wherein: the guide surface begins at a first edge of the air passage opening and the end region ends at the opposite edge of the opening; and the end region does not overlap with an adjacent surface that continues at the opposite edge of the air passage opening. ### Claim 2 (depends on 1) The air guide of claim 1, wherein the air passage opening has a V-shaped cross-section. ### Claim 3 (depends on 1) The air guide of claim 1, wherein the guide surface extends downwardly from a corresponding surface of the air guide body. ### Claim 4 (depends on 1) The air guide of claim 1, wherein the air passage opening is configured to overlap the guide surface and the end region. ### Claim 5 (depends on 1) The air guide of claim 1, wherein the air passage opening, the guide surface and the end region are arranged in a separate component configured for connection to the fan cowling. ### Claim 6 Air guide for a motor vehicle, the air guide comprising: a plurality of air guide surfaces; an air passage opening arranged between adjacent air guide surfaces; a guide surface which extends from an air guide surface and corresponds to the air passage opening; and an end region which extends from the guide surface in a plane which is substantially parallel to a plane of the surface of the air guide body, wherein: the guide surface begins at a first edge of the air passage opening and the end region ends at the opposite edge of the opening; and the end region does not overlap with an adjacent surface that continues at the opposite edge of the air passage opening. ### Claim 7 (depends on 6) The air guide of claim 6, wherein the air passage opening has a V-shaped cross-section. ### Claim 8 (depends on 6) The air guide of claim 6, wherein the guide surface extends downwardly from a corresponding surface of the air guide body. ### Claim 9 (depends on 6) The air guide of claim 6, wherein the air passage opening is configured to overlap the guide surface and the end region. ### Claim 10 (depends on 6) The air guide of claim 6, wherein the air passage opening, the guide surface and the end region are arranged in a separate component configured for connection to the fan cowling. ### Claim 11 A motor vehicle, comprising: an air guide having: a plurality of air guide surfaces; an air passage opening arranged between adjacent air guide surfaces; a guide surface which extends from an air guide surface and corresponds to the air passage opening; and an end region which extends from the guide surface in a plane which is substantially parallel to a plane of the surface of the air guide body, wherein: the guide surface begins at a first edge of the air passage opening and the end region ends at the opposite edge of the opening; and the end region does not overlap with an adjacent surface that continues at the opposite edge of the air passage opening. ### Claim 12 (depends on 11) The motor vehicle of claim 11, wherein the air passage opening has a V-shaped cross-section. ### Claim 13 (depends on 11) The motor vehicle of claim 11, wherein the guide surface extends downwardly from a corresponding surface of the air guide body. ### Claim 14 (depends on 12) The motor vehicle of claim 12, wherein the air passage opening is configured to overlap the guide surface and the end region. ### Claim 15 (depends on 13) The motor vehicle of claim 13, wherein the air passage opening, the guide surface and the end region are arranged in a separate component configured for connection to the fan cowling.
