The F-hose is the branched line that feeds the diverter valves on the 996 Turbo, and the factory rubber splits with age, which bleeds off the pressure signal and leaves the valves slow to react on lift off. This replacement is moulded from high quality silicone with three to five reinforcement layers, so it stays sealed under boost pressure and engine bay heat. A matching Y-hose kit, do88-kit244S, and the clamp kit clamp-kit243 are sold separately.
