Beru ultra-x aren't like Bosch Platinum +4 at all other than look. The Beru's are copper core & use 4 electrodes. The 230Kompressor & 230SLK come only with this style of plug from Beru.
If you got a set of Bosch that end in DC not DC0 from Germany then they are OLD stock & still good ones!
The (0) at the end means a WIDER heat range! & therefore costs more!
