Intake system

The air intake (11) of the internal combustion engine induction system is tapered forming a bell mouth shape and is fastened to a ring (13) to the upstream end of an air tube (10). The tube may be a flexible hose made of sheep's wool (12) which can act as a silencer. A ring (14) on the downstream end of the tube may connect it to a large housing (15) for an air filter (16). Air passes into the induction manifold from the filter.
