A filter pipeline for an air intake system of an internal combustion engine has a tubular body and a filter element arranged in the tubular body. The filter element is a filter bag of a flexible material that has an opening and is attachable in the area of the opening to the tubular body. The filter bag and an inner wall of the tubular body are shaped such that in a circumferential direction of the pipeline different spacings are provided between the filter bag and the inner wall of the tubular body.
