This air hose connects the intake system to the full load regulator of a fuel injection system in a Citroën DS. The hose guides intake air to the control unit for correct adjustment under different engine loads. The material tolerates conditions in the engine bay and fits existing clamps and connection points. Shape and length suit the available space around engine and body. The air hose supports stable idle speed, correct power delivery and consistent throttle response. It also helps limit leakage losses in the intake path and prevents unwanted pressure changes inside the control system during operation of the vehicle.
