ABSTRACT:
An air intake pipe able to increase intake of air and bendable freely for assembly includes an accelerating inner pipe, an air intake outer pipe and a flexible fit pipe. The accelerating inner pipe has one end connected with the air intake end of an engine, and the air intake outer pipe has one end connected with an air filter. The accelerating inner pipe and the air intake outer pipe respectively have the other end movably fitted with the flexible fit pipe. The diameter between the air intake outer pipe and the accelerating inner pipe is shrunk to increase the intake and pressure of air. The rotatable fit structure between the flexible fit pipe and the accelerating inner pipe and the air intake out pipe, and the flexibility of the flexible fit pipe enable the air intake pipe to be installed in various engine rooms of different automobiles.
