The spatially curved oscillator tubes are closely seated on the cylinder head and are partially integrated in that wall of a common intake housing which faces the cylinder head, and are completed by shell halves. The intake system preferably includes injection molded synthetic material, and is fastened on the cylinder head by an aluminum fastening rail or strip, or includes reinforced synthetic material, and is fastened directly on the cylinder head. An air-filter element can be installed as a part of the intake housing.

A multi-part intake system having a flow direction of suctioned intake combustion air for multi-cylinder internal combustion engines which include a cylinder head for said cylinders, said intake system comprising: an intake housing including a cylinder-head side as well as having an inside and having an intake housing wall as well as inside and outside surfaces; and intake oscillator tubes which are curved in more than one plane and which extend inside said intake housing as well as along said intake housing wall toward the cylinder head, said oscillator tubes each being connected with said intake housing in common and the cylinder head as well as respectively having a first end and a second end, with said first end of each oscillator tube being provided with an intake funnel which opens into said common intake housing, and with the second end of each oscillator tube being seated closely on said cylinder head, said intake oscillator tubes at least for a portion thereof consisting of adjoining shell halves having abutting surfaces formed along a single plane thereof lying in flow direction of suctioned intake combustion air with the shell halves being connected with each other, wherein said intake oscillator tubes cross each other inside the common intake housing, said adjoining shell halves crossing each other at the tube crossings which lie substantially in a single plane perpendicular to said plane of said abutting surfaces being unified into one structural part, said intake housing wall on the cylinder-head side being constructed as a shell half.
