An apparatus for mixing intake air and exhaust gases of an internal combustion engine includes a chamber having an inlet to supply a stream of intake air, and a second inlet that receives an exhaust gas flow. The second inlet includes a section extending into the chamber of the mixer that has an outer surface that is elongated in cross-section along a longitudinal axis of the chamber in the direction of flow of the flowable media. The mixing apparatus mixes the intake air and exhaust gases without high pressure head loss across the apparatus.
