This kit replaces the eight rubber charge air hoses of the RS4 2.7 BiTurbo turbo and intercooler system with silicone: both turbo outlet hoses, both intercooler inlet hoses, both intercooler outlet hoses and the two diverter valve hoses. Every hose is moulded in high quality silicone with three to five reinforcement layers, so it holds full boost pressure and the heat of compressed charge air without the swelling and splitting that finishes the factory rubber. Matching hose clamps are sold separately as clamp-kit224.
