Air intake conduit system for an internal combustion engine

The air induction port system comprises a suction pipe housing with suction ports leading to the cylinders and which are then divided into two individual ports each having a swirl flap (7) mounted on a shaft (6) rotatable by a drive. The shaft with the swirl flap is mounted in a housing component (9) which is fitted in the suction pipe housing in such a way that the shaft engages in the drive. The housing component is fixed in the suction pipe housing by a clamp connection.
