    2015-2019 Subaru STI Boost Tube Kit by Perrin Performance

    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.

    Boost Tubes - 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.

    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.

    Coolant Overflow Tank - The PERRIN Boost Tube 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.

    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.

    • CNC Mandrel Bent from High Quality Aluminum
    • Black or Red Powder Coated Finish for Protection From the Elements
    • Perfectly Matched Boost Tubes for Optimal Flow
