The Subaru WRX is known for its impressive performance and tuning potential. Upgrading the intercooler is one of the most effective ways to enhance power gains, particularly for those running a Stage 2 setup. In this article, we will explore the benefits of the GrimmSpeed 22x12x3.5 intercooler and how it impacts the performance of a Stage 2 WRX.
Understanding the Role of an Intercooler
An intercooler plays a crucial role in the performance of turbocharged engines. It cools the air entering the engine, allowing for more dense air and, consequently, better combustion. This results in increased horsepower and torque, making intercooler upgrades vital for any performance-oriented build.
Why Choose the GrimmSpeed 22x12x3.5 Intercooler?
The GrimmSpeed intercooler is specifically designed for the Subaru WRX, providing a perfect balance between size, efficiency, and performance. Here are some reasons why it stands out:

Power Gains with Stage 2 Setup
A Stage 2 WRX typically involves a performance tune, upgraded exhaust, and enhanced intake systems. Adding the GrimmSpeed intercooler to this setup can lead to significant power gains. Here’s what you can expect:
- Improved Horsepower: Users report gains of up to 20-30 horsepower with the intercooler upgrade.
- Enhanced Torque: Torque figures can increase by a similar margin, improving overall drivability.
- Better Throttle Response: The cooler intake air leads to more responsive acceleration.
- Consistent Performance: Reduced heat soak ensures power levels remain stable during extended driving sessions.
Installation Process
Installing the GrimmSpeed intercooler is a manageable task for those with basic mechanical skills. Here’s a brief overview of the installation process:
