Important Notes:

• Aftermarket Intake Required! Depending on brand of intake there may be a compatibility issue and a new intake or modification will be required. Short-ram intake recommended for ease of installation.
• The use of factory service manuals is highly recommended. These can be purchased at the dealer, or downloaded from http://techinfo.subaru.com
• Boost tubes will have tight clearances next to battery and secondary air pump cover. Take time in moving boost tubes to clear parts.
• Be prepared to empty your windshield washer tank into a container.
• Installation of this part does require destruction of your OEM windshield washer tank.
• There will be a few extra parts included with this kit that may not be used in your installation.
• Due to the differences between LHD/RHD and the 15-17 vehicles, perfect fit cannot be guaranteed. Rather, this kit is designed to be a close fit for all models but additional parts or modifications to piping or engine bay components may be required.

Boost Tubes:

PERRIN boost tubes 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.

T-Bolt Clamps:

PERRIN Performance T-bolt clamps are standard on PERRIN intercoolers. They are designed for uniform clamping at all points around the band. The wider band distributes the force over a larger area and the fine threaded bolts with nylon lock nuts allow for accurate torque and proper clamping. Never worry about having to re-tighten down the road, plus each PERRIN logo-ed clamp is made in the USA and has the torque spec engraved on each one. Advantage PERRIN!

Coolant Reservoir:

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. It looks great and makes the silk screened logo pop.

Washer Tank:

The PERRIN Boost Tube Kit includes a PERRIN Washer Fluid Tank. With 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.

Construction:

PERRIN Boost Tubes 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.

Finish:

Every PERRIN Boost Tube is powder coated for further protection from the elements, making it look awesome for years to come. Our boost tubes come in two finish options, texture powdercoated black, and texture powdercoated red
