2015+ Subaru WRX Perrin Boost Tube Kit ONLY - Red Tubes/Black Couplers (No Intercooler)

The PERRIN Boost Tube kit is available for those of you who have purchased the PERRIN FMIC Core. These tubes have been fabricated from aluminum, and have been CNC bent to reduce turbulence under boost to promote quick spool and optimum performance. Each end of these boost tubes also feature over-sized beaded ends to make sure the provided worm clamps stay connected throughout all boost levels.

Other features include 2.25" tubing, and pipes will come for both the hot side which are routed through the engine bay next to the battery, and down behind the radiator to the intercooler. The cold side pipes are mounted as high as possible to clear most turbo and intake combinations as they make their way to the throttle body through the engine bay.

Additionally, there will be a coolant expansion tank, and a coolant overflow tank along with all of the required brackets, worm clamps, and hardware needed for installation. These pipes have been powder-coated a textured black finish to have extra protection against rust and corrosion, and they will come provided with a blow-off valve flange and black silicone couplers.
