Abstract:
1. A filter element for an air inlet system, comprising: an annular filter medium in the form of an annular bellows having an open interior and two axially opposing ends; wherein air flow through the filter medium radially between a radial exterior face of the filter medium and a radial interior face at the open interior of the filter medium; wherein the filter medium is operable for cleaning raw air; an inflow protection element arranged at and overlaying a portion of the radial exterior face, and deflecting flow in an inflow area of the filter medium; a terminal disk arranged on and covering said filter medium on a first one of said axially opposing ends of said filter medium; wherein the first axial end of the filter medium is embedded into material of the terminal disk, securing the terminal disk onto the filter medium; wherein the inflow protection element is directly embedded into the material of the terminal disk of the first axial end of the filter medium, such that an end part of the inflow protection element is surrounded by the material of the terminal disk; a second terminal disk arranged on an opposing second axial end of the filter medium; wherein the inflow protection element at an axial end proximate to the second terminal disk has at least one plug in connection element; a counter holder having a first end secured to the second terminal disk, the counter holder having at least one complimentary plug in connection element, the complimentary plug in connection element configured to engage with the at least one plug in connection element to connect and secure the inflow protection element to the second terminal disk.
