Pipe for an car engine air-intake circuit, and circuit comprising same.

The pipe (1) comprises an internal elastomer layer (10), an external elastomer layer (16), an intermediate elastomer layer (12) intended to facilitate an adhesion between the internal and external elastomer layers, and a reinforcement structure (14), which is radially disposed between the intermediate elastomer layer and the external elastomer layer. The reinforcement structure comprises a knitted or plaited multifilament fabric made of a polyethylene teraphtalate material. An independent claim is included for an air intake system of an automobile motor vehicle.
