PURPOSE: An intercooler connection pipe is provided to reduce radiation noises by forming villus along the outer surface of the intercooler connection pipe. CONSTITUTION: An intercooler connection pipe(20) comprises a pipe(21) having a predetermined diameter and which is made of a plastic material; and villi(22) formed along the outer surface of the pipe. Each of the villi has a protrusion formed at the root thereof so as to improve a strength. The villi are formed integrally with the pipe during the molding process. Alternatively, the villi are formed separately, and implanted into the outer surface of the pipe.
