The integrated intake module 10 for an i.c. engine 22 has an air box 14 that encloses an internal space and contains a particulate filter 24 that separates a clean air space 26 from a dirty air space 28. A throttle body assembly 16 receives clean air from the air box 14 and delivers the air to a plenum 18. Runners 20 that have respective inlets at which clean air from the plenum 18 enters extend lengthwise to respective outlets 44 for delivering clean air to cylinders of the engine 22. At least a portion of the length of each runner 20 is disposed on the wall of the air box 14 about the dirty air space 28. In an imaginary vertical plane passing through the centerline 90 of each runner 20, the whole runner outlet 44 is at a higher level than that of the centerline 88 of the filter cartridge 24. The main parts of the intake module may be made from plastics and joined along their mating perimeters to create fluid-tight joints. In a modification (fig.5), the air filter is rectangular and the runners 20 run upward from plenum 18 along side wall 58, across the top wall and part-way down side wall 60 where they curve into flange 74. In a further modification (fig.6), dirty air enters at the bottom of the module (200) and the end of the air box is closed by a lid (240) having triangular side walls (246, 248).
