No idea, but I suspect that people selling swirlflap blanks will probably know that sort of thing.

Swirl flaps are at the engine side of the air inlet manifold, and open and close to allow more air to each cylinder at higher engine speeds.
There is normally one for each cylinder.
I think that 320d has 4 cylinders.
