This intercooler pipe is made from 2.5” (63mm) high quality aluminum. This is larger than the OEM pipe for improved air flow. CNC-machined sensor flange and mandrel bent pipe ensures perfect fitment. The hoses are a stronger alternative to OEM hoses! These hoses have 4 PLY reinforcement compared to OEM hoses that have 1 PLY reinforcement. Another advantage of these hoses is the silicone material that withstands high temperature for long time. This intercooler pipe kit is a terrific upgrade if your original hoses starts to crack from age or maybe you use your car in a way that the original hoses where not designed for. This kit is available with three different hose colors Blue / Black / Red. There are no performance differences between the different colors, choose which color you think will be best for your car. All parts are included to replace all OEM intercooler hoses and pipe.
