Abstract
An engine intake duct is formed by securing a hydrocarbon-adsorbing element to a frame to form an insert, positioning the insert in registry with a blow-molding core, placing a molten plastic parison and mold around the insert and core, and blow-molding the parison to form a shell engaging the frame to retain the insert with a surface of the insert exposed to a hollow interior of the shell.
