Mitsubishi Evo 7/8/9 2.5" Aluminum Upper Intercooler Pipe Kit by STM

The STM 2.5" aluminum upper intercooler pipe kit for the Evo 7/8/9 features smooth, mandrel bent, lightweight 2.5" aluminum piping with bead-rolled ends. Choose brushed, polished, gloss black or a durable wrinkle black finish. Available with either a TiAL, HKS, GReddy or stock blow off valve flange and includes an AIT bung. (A plug is included if AIT is not needed for your application).

This kit is designed to work with any intake manifold that utilizes the factory throttle body location, including OEM, Skunk2, JMF Sheetmetal, Driven Innovations, AMS F1 and so on. This will not fit with the JMF Billet manifold. Select the proper coupler size to match your throttle body in the purchase menu. We offer a 2.5-2.75" to match the stock TB or a 2.5-3" which fits with the S90 70/74 and the Full Blown. Please double check your TB size if you have another style.

These pipes have been test-fitted and are compatible with the STM, OEM and Buschur intercoolers, and they will also work with any aftermarket intercooler utilizing the stock-placement of piping such as ETS. The included 2.5" coupler will fit a 2.5" intercooler outlet (which is standard on most intercoolers). All STM UICP kits will include an AIT bung welded onto the bottom pipe that connects to the intercooler. If you do not need to run an AIT sensor, we also include a black plug to seal it off.
