1. A duct system for an air intake system for a vehicle, the duct system comprising:
a first duct including
a first duct wall that defines a first duct opening and forms a conduit configured for conveying fluid through the first duct opening in an axial direction of the first duct opening, and
a rim fixed with the first duct wall and extending from the first duct in the axial direction of the first duct opening, and disposed around the first duct opening, with a first rim portion and a second rim portion disposed along opposite sides of the first duct opening in a lateral direction of the first duct opening perpendicular to the axial direction of the first duct opening, and
a second duct including a second duct wall that defines a second duct opening in fluid communication with the first duct opening, and forms a conduit configured for conveying fluid through the second duct opening,
wherein when the second duct is installed on the first duct in an installation direction along the lateral direction of the first duct opening, the second duct wall engages the first rim portion such that the rim obstructs movement of the second duct in the installation direction, and extends over the second rim portion.
