How should I handle “how to choose Teile plus rothbury” when shopping for “Teile plus rothbury”?

Choose “Teile plus rothbury” by matching the full vehicle identity and the old component number, then compare construction, warranty, and installation risk. Use an OEM catalog or a seller fitment record as evidence. A keyword match is discovery; it is not confirmation that the component fits. End with a go / no-go rule the reader can apply without jargon.
