The process of compressing incoming air to create boost and power also has a nasty byproduct of heat.

Heated air lacks the density to make higher horsepower, increases detonation and forces the ECU to pull timing. All of which reduce the power you are looking to create.

Enter the PERRIN™ Front Mount Intercooler upgrades. With gargantuan cores, cast endtanks, high velocity tubing and proper mounting supports, there simply isn’t a better choice for your car, period.

These intercoolers will support more than 1000 HP and due to our stringent quality control process have less than 1/4 psi drop across the core at 20 psi., improving throttle response and putting the boost where it belongs in the the combustion chamber!

Fits: Subaru WRX STi 2004-2007
