In the 4-cylinder engines (M47 ..), the flaps always have a diameter of 22mm.
In the case of the 6-cylinder engines (M57 ..), the manufacturer made a change in the size of the swirl flaps in the course of 2004. As a guide, therefore:
22 mm diameter for vehicles up to 2004
32 mm diameter for vehicles from year 2004
From our experience we know, however, that depending on the model, there may already be deviations from this rule.
Therefore, you should check the required size on the vehicle.
You can determine the diameter without removing the swirl flap.
If the swirl flaps on your intake bridge are mounted with their screw axis parallel to the push rod of the swirl flap adjustment, then 22mm flaps have been installed. (Pic.1)1
If the screw axis should be turned by approx. 40 ° to the push rod, flaps with the diameter 32mm were installed (pic.2)
You can also check the screw distance (pic.3)
