A filter housing part with an air filter element that filters the combustion air is provided. The filter housing part has an inlet section and at least one outlet for the filtered combustion air. An air connection between the outlet section of the intake housing part and an inflow side of the air filter element is provided. A fixed intake pipe part is arranged between the outlet section of the intake housing part and the inlet section of the filter housing part. The fixed intake pipe part at least partially forms the air connection between the outlet section of the intake housing part and the inflow side of the air filter element. ## Claims ### Claim 1 An intake module of an air intake tract of an internal combustion engine of a motor vehicle, the intake module comprising: an intake housing part comprising an inlet section and an outlet section; at least one inlet opening for combustion air to be filtered to enter the inlet section of the intake housing part; an inlet grid arranged in the at least one inlet opening of the intake housing part; wherein the outlet section is arranged at an opposite second end of the intake housing part relative to the inlet section; a plurality of water separating surfaces formed on circumferential housing walls of the intake housing part, the plurality of water separating surfaces each elongated horizontally in a direction from the inlet grid to the outlet section of the intake housing part, the plurality of water separating surfaces extending parallel to each other, the plurality of water separating surfaces each having a first end positioned at the inlet grid, and terminating at the opposite second end of the inlet section of the intake housing part; the plurality of water separating surfaces providing an enlarged surface area that is active for water separation; and a water drain outlet opening arranged in a bottom wall of the intake housing part below the plurality of water separating surfaces; a filter housing part comprising an air filter element configured to filtrate the combustion air, the filter housing part further comprising an inlet section and further comprising at least one outlet for the filtered combustion air; an air connection disposed between the outlet section of the intake housing part and an inflow side of the air filter element; a fixed intake pipe part arranged between the outlet section of the intake housing part and the inlet section of the filter housing part, wherein the fixed intake pipe part at least partially forms the air connection between the outlet section of the intake housing part and the inflow side of the air filter element. ### Claim 2 (depends on 1) The intake module according to claim 1, wherein the filter housing part and the intake housing part are arranged so as to be displaced relative to each other. ### Claim 3 (depends on 1) The intake module according to claim 1, wherein a flow cross-section provided in the intake housing part decreases in a main flow direction of the combustion air. ### Claim 4 (depends on 1) The intake module according to claim 1, further comprising at least one water separating device arranged upstream of the inflow side of the air filter element. ### Claim 5 (depends on 1) The intake module according to claim 1, further comprising at least one water separating surface arranged in the intake housing part. ### Claim 6 (depends on 1) The intake module according to claim 1, further comprising at least one water separating surface arranged in the intake pipe part. ### Claim 7 (depends on 1) The intake module according to claim 1, further comprising at least one particle separating device arranged fluidically between the at least one inlet of the intake housing part and the inflow side of the air filter element. ### Claim 8 (depends on 1) The intake module according to claim 1, further comprising at least one drainage device configured to drain media separated from the combustion air, wherein the at least one drainage device is arranged between the inlet of the intake housing part and the inflow side of the air filter element. ### Claim 9 (depends on 1) The intake module according to claim 1, wherein the filter housing part and the intake housing part are flat. ### Claim 10 (depends on 1) The intake module according to claim 1, wherein the filter housing part is flat. ### Claim 11 (depends on 1) The intake module according to claim 1, wherein the intake housing part is flat.
