In the performance catalog it specifically says that it is for all E9x except not for the 335. I assume that the air intake cover (which is higher on the N54 than the N52) is bumping up against it. I would have to see one, but it looks as though one could pop in a spacer/washer to elevate it where it attaches to the strut tower. But if it were that easy then surely BMW would have provided that adjustment.
