The E46 Motorsports Finned cover is avail as a BMW Motorsports part; slightly different casting than the Z4 unit. Same effect also and avail brand new from BMW

The Higher capacity of oil compared to standard cover is nice for thermal stress as well; the cover is also heavier and stiffer/stronger (more metal)






BMW Motorsports cover (NEW):



Z4 finned cover (used)



Casting difference at bolt mounting: the required length of bolts are different!
