An induction system in an engine is provided. The air induction system includes an induction conduit including an air flow passage in fluidic communication at least one combustion chamber in the engine and a passive-adsorption hydrocarbon trap positioned within the induction conduit, a portion of the passive-adsorption hydrocarbon trap defining a boundary of the air flow passage, the passive-adsorption hydrocarbon trap including a breathable layer coupled to a substrate layer coupled to the induction conduit, a hydrocarbon adsorption layer interposing the breathable layer and the substrate layer.

1. A system, comprising: an air box having an air filter, the air box having a hydrocarbon trap and a removable lid, and internal reinforcing structures creating one or more pockets; anda hydrocarbon trap material positioned within one or more of the pockets, the lid defining a boundary of the air flow passage, the air box including a layer coupled over the pockets. 2. The system of claim 1, where the hydrocarbon trap is a bypass hydrocarbon trap. 3. The system of claim 1, where the layer is a breathable non-woven polyester material. 4. The system of claim 1, where a cross-section area of the air flow passage is interrupted when transitioning into a section of the induction conduit having the bypass adsorption hydrocarbon trap coupled thereto. 5. The system of claim 2, where the internal reinforcing structure is one or more ribs extending perpendicularly from a base to the removable lid under the pockets. 6. The system of claim 5, where the base and the ribs comprise of a non-breathable material. 7. The system of claim 1, where a space between the internal reinforcing structure, a base, and the removable lid defines a volume of a single pocket. 8. The system of claim 1, where the hydrocarbon trap material is loosely packed into each of the pockets of the hydrocarbon trap. 9. The system of claim 1, where the removable lid rests upon the internal reinforcing structures with the layer located therebetween. 10. The system of claim 1, where the removable lid is coupled to the internal reinforcing structures along a periphery of the removable lid. 11. The system of claim 1, where the removable lid comprises a first layer and a second layer, where both layers are breathable and at least one of the layers is adhesive and able to bond to a top of the internal support structures. 12. The system of claim 11, where the base and the internal reinforcing structures are non-breathable and do not allow a transfer of gases, liquids, and/or solids across membranes of the base and the internal reinforcing structures. 13. The system of claim 1, where the removable lid is contoured to be in face sharing contact with the internal reinforcing structures of the air box of the induction conduit. 14. A system, comprising: an airflow induction conduit in fluidic communication with an engine intake and including a recessed cavity;a bypass-adsorption hydrocarbon trap positioned within the cavity, forming a continuous, uninterrupted linear surface without sharp edges, ledges, or shelves, and defining a boundary of an airflow passage, the bypass-adsorption hydrocarbon trap including a hydrocarbon adsorption material located within one or more pockets; anda removable cover sitting on top of one or more ribs perpendicularly extending from a surface of the cavity, where a space located between the removable cover, the ribs, and the surface of the cavity defines a volume of an individual pocket of the bypass adsorption hydrocarbon trap. 15. The system of claim 14, where the bypass hydrocarbon trap comprises a plurality of the individual pockets, and where the individual pockets comprise an amount of hydrocarbon trapping material. 16. The system of claim 14, where the removable lid is breathable and allows gas to enter the space of the pocket. 17. The system of claim 14, where the surface of the cavity and the ribs are non-breathable and gas does not pass through the ribs or the surface of the cavity. 18. The system of claim 14, where the removable cover is coupled to one or more of the ribs and the surface of the cavity along a periphery of the removable cover. 19. A system, comprising: an air box having an air filter, the air box having a hydrocarbon trap and a removable lid, and internal reinforcing structures creating a plurality of pockets; anda hydrocarbon trap material positioned within some, but not all, of the pockets, the lid defining a boundary of the air flow passage, the air box including a layer coupled over the pockets.
