New high pressure fuel lines are required for the RS4 SC System.
The design and mfg process involves tight tolerances and multiple inspection at various points to insure proper performance, fit, and safety.
Many iterations between design considerations, mfg possibilities, mfg processes, assembly order were needed to reach this final state.
