Swap out your overheated factory top mount intercooler for the PERRIN Front Mount Intercooler to get the most out of your turbocharged STi.  Add power and a new bold look all in one.

Construction

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

Boost Tubes

Right off the turbo a smooth offset coupler carries the hot side air charge to a perfectly matched 2.25″ boost tube.  PERRIN 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.

Coolant Overflow Tank

The PERRIN front mount intercooler kit includes a PERRIN Performance 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 Performance coolant overflow tank is protected from the elements by a black texture powder coating.

Washer Tank For 2015+ Models

The PERRIN boost tube kit includes a PERRIN washer fluid tank.  With how the boost tubes are routed through the intercooler, the OEM tank conflicts with the space required.  The PERRIN washer fluid tank is protected from the elements by a black powder coat finish.

Finish

Every PERRIN boost tube is powder-coated for further protection from the elements, making it looks awesome for years to come.  PERRINS boost tubes come in two finish options, texture powder coated black and texture powder coated red.
