For 328i's running M3 clutch and M3 3.0/3.2 slave cylinder the hose is still the same as any other E36.
E36 M3 3.2 has a pressure switch on the OE hose, M3 3.0 and 328i don't, but any E36 braided hose works for all models, in the case of 3.2 you'll have to bypass the sensor or buy a T adaptor. I recommend HEL.
