Front Mount Intercooler for 2015-2019 Subaru WRX by Perrin

Our intercooler support beam is constructed from boxed steel and powder coated black. The installation of the PERRIN Front Mount Intercooler for 2015-2017 WRX does not require the removal of the driver-side bumper beam support. The most important part of any intercooler system is the core. The core cools the charged air on the way to the engine. The factory Subaru tube and fin intercooler was designed to be easy to manufacture, but is not good for performance. Our testing has shown the optimum core design is the 3/8” bar and plate style that has a 3/8” charge air and ambient air path, instead of the common 1/4” size. The PERRIN bar and plate core design is much more durable than tube and fin with the ability to withstand rocks and other debris, which may enter the scoop. The PERRIN intercooler core is 28” long x 9.25” tall x 3.5” deep with a volume of 906.5 cu-in. giving the PERRIN Intercooler the best overall design for cooling and pressure drop! Every PERRIN intercooler is powder coated to further protect your intercooler from the elements making it look awesome for years to come. Our intercoolers come in two finish options, a bright silver or stealth black powder coat.

The PERRIN designed end tanks control for near perfect dispersal of hot air across the intercooler core. By eliminating any 90º corners adding a smooth, and gradual taper from top to bottom turbulence is eliminated. Each end tank incorporates an innovative mounting tab to secure the core to the mounting beam. 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.

PERRIN is one of the only intercooler manufactures who pressure tests every intercooler. We pressurize every intercooler to 50 psi. on our special jigs. This ensures you never get a core with a leak! Even the slightest leak can cause your vehicle to lose power, literally bleeding turbo boost pressure out the intercooler. The PERRIN Front Mount Intercooler kit includes a PERRIN Washer Fluid Tank. 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. It looks great and makes the silk screened logo pop. The PERRIN Front Mount Intercooler 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.

Great product

Great product, easy to install, it’s nice that it comes with coolant catch cans. MAP had great customer service with this item and fast shipping. The charge pipe from the turbo to the hot side of the intercooler does run near the air filter so you have to be creative with the heat shield! All and all a great item!
