HPS Blue Upper Intercooler Pipe (UICP) is a direct replacement for Lancer EVO X factory upper intercooler pipe. Made from lightweight 2.5? mandrel bent aluminum tubing, the pipe features one piece design which has a smooth, non-turbulent 2? to 2.5? transition for maximum performance. The bead rolled pipe ends prevent couplers from popping off under boost. The included HPS high temp 4-ply reinforced silicone hoses can withstand minimum 50+ psi of boost and replace the factory rubber couplers, which often crack or fail over a period of time. The intercooler pipe optimize and smooth out the air flow, deliver performance gains in mid-range without re-tuning the ECU. Fits Mitsubishi Evolution 10 GSR and MR Models (USDM, JDM and European). Compatible with all aftermarket intercoolers with factory outlet angle.
