Complete charge air hose kit for the C5 RS6 twin turbo V8, covering the turbo inlet, turbo outlet, intercooler inlet and intercooler outlet hoses on both banks. Each hose is manufactured in high quality silicone with three to five layers of reinforcement depending on inner diameter, so it holds boost without ballooning where the original rubber softens, delaminates and eventually splits, a well known cause of boost loss on this engine.
