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. 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.

Intercooler Core

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!

Intercooler Support Beams

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.

Finish

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.

Cast End Tanks

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.

Coolant Reservoir

The PERRIN Front Mount Intercooler kit includes a PERRIN Performance 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 Performance coolant overflow tank is protected from the elements by a black texture powder coating. It looks great and makes the silk screened logo pop.

Pressure Testing

PERRIN Performance 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 loose power, literally bleeding turbo boost pressure out the intercooler.

Weight

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!

Logo Stencils

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.
