Swap out your overheated factory top mount intercooler for the PERRIN Front Mount Intercooler to get the most out of your turbocharged WRX or STI. Add power and a new bold look all in one. 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. 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 are not good for performance. Our testing has shown the optimum core design is 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 are 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, and it fills the opening of the WRX/STI bumper perfectly! Our intercooler support beam is constructed from boxed steel and powder-coated black. Competitors use inexpensive aluminum bumper beams which save a little weight but are easily destroyed in a collision. 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 Performance designed end tanks control for near perfect dispersal of hot air across the intercooler core. By eliminating any 90? 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 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. 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.
