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.
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, and it fills the opening of the STI bumpers perfectly!
Check out the comparison.
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 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 Performance Clamps are standard on PERRIN Intercoolers. They are designed for uniform clamping at all points around the band. The wider band distributes the force over a larger area and the fine threaded bolts allow for accurate torque and proper clamping. Never worry about having to re-tighten down the road, plus each PERRIN clamp is made in the USA and has the torque spec engraved on each one. Advantage PERRIN!
The PERRIN Front Mount Intercooler kit includes a PERRIN Performance washer fluid tank. How the boost tubes are routed through to the intercooler, the OEM tank conflicts with the space required. The PERRIN Performance coolant overflow tank is protected from the elements by a black powder coating. It looks great and makes the silk screened logo pop.
The PERRIN Front Mount Intercooler kit only adds 9lbs of weight! If you take all the factory pieces you remove and compare them to the PERRIN parts you are installing, you will find you only added 9lbs!
Included with our front mount intercooler is a free PERRIN logged intercooler stencil. Use the stencil to easily paint the PERRIN logo across the front of your intercooler. Simply peel, stick, paint, and remove.
