Perrin [15-21 WRX] FMIC Boost Tube Box w/ Black Boost Tubes and Black Couplers

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! We choose to take the smoothest, shortest path to get air to and from the intercooler.

• BOOST TUBES ONLY - intercooler core NOT included (sold separately); designed to work with the PERRIN Front Mount Intercooler
• Black powder-coated boost tubes with black silicone couplers
• 2.25" CNC mandrel-bent aluminum tubing with oversized beaded ends
• Hot-side charge routed through the engine bay next to the battery and down behind the radiator to the intercooler; cold-side tubes mounted as high as possible to clear all turbo and intake combinations on the way to the throttle body

• This part WILL fit the 2018+ WRX, but you have to remove a Front-Side Support Beam to do it
