This is the Perrin Performance 15-21 Subaru WRX/STI Front Mount Intercooler Core + Mounting Beam - Black Core. Part perPSP-ITR-437-1BK. An intercooler cools the charge air from the turbo or supercharger for denser air and more consistent power.

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.

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.
