This kit replaces the two rubber turbo outlet hoses that carry compressed charge air away from the turbochargers on the 993 Turbo, the hoses that soften and blow off under boost once the rubber has aged. Both are moulded from high quality silicone with three to five reinforcement layers, so they hold full boost pressure and charge air temperature without swelling or ballooning. Matching hose clamps are sold separately.
