PERRIN Boost Tube Box Subaru 2015+ WRX Black Boost Tubes with Black Couplers
A key to making more power on any turbocharged engine is the addition of a high performance air-to-air intercooler. This part in the simplest of terms, cools the air going from the turbo into your engine, much the same as a radiator cools the water inside the engine, by transferring the excess heat way using multiple passages through a core. A PERRIN intercooler fits easily to the front of your Subaru to maximize cooling.
*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.
