AMS Performance Polished Upper Intercooler Pipe for 2008-2017 Mitsubishi Lancer, Evolution X, & Ralliart

Fits 2008-2017 Mitsubishi Lancer (DE, ES, GTS, Ralliart) and Lancer Evolution X (GSR, MR, SE, Final Edition) models.

The AMS Performance Upper Intercooler Pipe (UICP) is a high-flow, direct replacement for the restrictive factory piping. Constructed from 2.5-inch mandrel-bent aluminum, this pipe features a smooth 2-inch to 2.5-inch transition designed to minimize turbulence and optimize charge air delivery to the engine. To ensure reliability under high-boost conditions, the pipe ends are bead-rolled and the assembly utilizes factory mounting points on the core support to prevent coupler separation.

This kit replaces all factory rubber couplers with heavy-duty 4-ply silicone components capable of enduring over 50 psi of boost. A dedicated silicone hump hose is included to accommodate engine movement and prevent stress-related tearing. Each unit is TIG-welded by hand and finished in a high-luster polished aluminum for a professional engine bay appearance.
