The AMS EVO X upper intercooler pipe is a direct replacement for the factory upper IC pipe on 2008–2015 Mitsubishi Evolution X models. Mandrel-bent 2.5" aluminum with a smooth 2"–2.5" transition, bead-rolled ends and quality 4-ply silicone couplers (rated for 50+ psi) reduce turbulence and coupler failures. TIG welded and offered polished, it delivered measured gains of roughly 5 awhp peak and 10+ awhp in the midrange without retuning.
