Perrin [15-21 STI] Front Mount Intercooler Boost Tubes & Hardware Black Pipes/Black Couplers

The Perrin Front Mount Intercooler Boost Tubes & Hardware kit for the 2015-2021 STI (black pipes, black couplers) is the piping half of the Perrin FMIC system - the intercooler core and beam are NOT included and must be purchased separately (Perrin FMIC core & beam PSP-ITR-437-1). The boost tubes are CNC mandrel-bent from aluminum tubing for weight reduction, with oversized beaded ends to keep hose clamps and couplers connected and sealed. A smooth offset coupler carries the hot-side air charge to a perfectly matched 2.25 in. boost tube - large enough to flow more WHP than most turbos can produce - routed through the engine bay next to the battery and down behind the radiator to the intercooler, with the cold-side tubes mounted as high as possible to clear all turbo and intake combinations.

• CNC mandrel-bent aluminum tubing with oversized beaded ends
