PERRIN 15-21 Subaru WRX/STI Front Mount Intercooler Core + Mounting Beam - Black Core

This is the Perrin front mount intercooler core and mounting beam assembly, specifically made for the 2015 through 2020 Subaru WRX STI. If you're pushing your STI's engine hard, especially with performance tuning, keeping the air charge cool is crucial. A hot air charge means less dense air, which can lead to reduced power and potentially knock. This kit replaces the factory top-mount intercooler with a much larger front-mount unit, significantly increasing its ability to absorb and dissipate heat.

The core itself is a well-built bar-and-plate design, offering a larger surface area and more internal volume than the stock intercooler. This means it can handle more heat and keep the intake air temperatures down, even under sustained load. Perrin includes a solid mounting beam that replaces the factory crash beam, providing a strong foundation for the larger intercooler and ensuring it sits securely in place. The black finish on both the core and the beam gives a clean, stealthy look behind the front bumper.

Installing this front mount intercooler is a significant upgrade for any STI owner looking to maximize their engine's performance and reliability, especially when running increased boost levels or modified tuning. It's designed to fit right into the factory location for the front-mount setup, though some minor modifications might be needed depending on other aftermarket parts you may have installed. This kit is a popular choice for those building a more powerful and responsive WRX STI.
