Air Hose

The engines air hose carries the air from the fanshroud (produced by the cooling fan inside) down towards the exhaust. The heat exchanger s that are attached to the exhaust then heats the air up which gives you the heating inside the car. Air hose must be fitted to your engine in order to keep good cooling efficiancy to the engine. If you wish to remove your air hose then the holes in the fanshroud must be blocked off with a pair of air hose block off plates.
