If you don't already have a set of PERRIN Boost Tubes, make sure you purchase them separately!

Important Notes:

• Aftermarket Intake Required! Depending on brand of intake there may be a compatibility issue and a new intake or modification will be required. Short-ram intake recommended for ease of installation.
• The use of factory service manuals is highly recommended. These can be purchased at the dealer, or downloaded from http://techinfo.subaru.com
• Fog lights can be left installed on 06-07 models, but not on 02-05 cars. These cars require fog light covers which can be purchased at dealer.
• There will be a few extra parts included with this kit that may not be used in your installation.
• Due to the differences between LHD/RHD and the 01-02, 03-05, 06-07 vehicles, perfect fit cannot be guaranteed. Rather, this kit is designed to be a close fit for all models but additional parts or modifications to piping or engine bay components may be required.
• Bumper trimming required

Swap out your overheated factory top mount intercooler for the PERRIN Front Mount Intercooler to get the most out of your turbocharged STI or WRX. Add power and a new bold look all in one!

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!

Intercooler Support Beam:

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.

End-Tanks:

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.

Pressure Testing:

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.

Logo:

Included with our front mount intercooler is a free PERRIN logo intercooler stencil. Use the stencil to easily paint the PERRIN logo across the front of your intercooler. Simply peel, stick, paint, and remove!
