PERRIN boost tubes for 2015+ Subaru WRX are CNC mandrel bent from aluminum tubing for better weight reduction. Every boost tube has an over sized beaded end to ensure the hose clamps and couplers stay connected and sealed! We choose to take the smoothest shortest path to get air to and from the intercooler.

Right off the turbo a smooth offset coupler carries the hot side air charge to a perfectly matched 2.25” boost tube. We chose 2.25" tubing for a smoother, cleaner, obstruction free routing while still being large enough to flow more WHP than most turbos can put out. The air charge then is routed through the engine bay next to the battery, and down behind the radiator to the intercooler. The cold side boost tubes are mounted as high as possible in the engine compartment to clear all turbo and intake combinations as it travels to the throttle body through the engine bay.

The PERRIN Front Mount Intercooler kit includes a PERRIN Washer Fluid Tank. How the boost tubes are routed through to the intercooler, the OEM tank conflicts with the space required. The PERRIN Washer Fluid Tank is protected from the elements by a black powder coating finish. It looks great and makes the silk screened logo pop

The PERRIN Front Mount Intercooler kit includes a PERRIN Coolant Overflow Tank. It adds clearance for better boost tube routing, holds more coolant than previous designs and uses the OEM tank cap for a great seal! The PERRIN Coolant Overflow Tank is protected from the elements by a black texture powder coating

Note: This boost tube kit is only for use with PERRIN front mount intercooler cores.
