The Subaru WRX is known for its performance and tuning potential. Among the many modifications enthusiasts consider, upgrading the intercooler is one of the most effective ways to boost power output. One popular option is the Cobb 27-inch intercooler, which can significantly enhance your WRX’s performance. In this article, we will explore how this intercooler works and the benefits it provides.
Understanding Intercoolers
Intercoolers play a crucial role in forced induction systems by cooling the air that enters the engine. This cooling process increases the density of the air, allowing for more oxygen to enter the combustion chamber. More oxygen means more fuel can be burned, which translates to increased power output.
Benefits of the Cobb 27-Inch Intercooler
The Cobb 27-inch intercooler is designed specifically for the Subaru WRX, offering several advantages over the factory intercooler. Here are some key benefits:
- Increased Cooling Efficiency: The larger surface area of the 27-inch intercooler allows for better heat dissipation, keeping intake temperatures lower.
- Improved Power Output: By reducing intake temperatures, the intercooler can help your WRX achieve up to 25 additional horsepower.
- Enhanced Reliability: The Cobb intercooler is built with high-quality materials, ensuring durability under high-performance conditions.
- Easy Installation: Designed as a direct replacement, the installation process is straightforward for most enthusiasts.
How the Cobb Intercooler Works
The Cobb 27-inch intercooler utilizes a bar-and-plate design, which is more efficient than the stock fin-and-tube design. This setup allows for better airflow and heat exchange. As air passes through the intercooler, it is cooled before entering the engine, which helps maintain optimal performance.
Installation Process
Installing the Cobb intercooler is a manageable task for those with basic mechanical skills. Here’s a brief overview of the installation process:
- Remove the factory intercooler by disconnecting the necessary piping and clamps.
- Install the Cobb intercooler in the same location, ensuring a secure fit.
- Reconnect the piping and clamps, making sure there are no leaks.
- Test the system to ensure everything is functioning properly.
Real-World Performance Gains
Numerous WRX owners have reported significant performance improvements after installing the Cobb 27-inch intercooler. On the dyno, many have seen gains of up to 25 horsepower, especially when paired with an appropriate tune. These gains can make a noticeable difference in acceleration and overall driving experience.
Conclusion
Upgrading to a Cobb 27-inch intercooler is an excellent choice for WRX enthusiasts looking to enhance their vehicle’s performance. With increased cooling efficiency, improved power output, and a straightforward installation process, this intercooler is a valuable addition to any performance build. If you’re aiming for higher horsepower and a more thrilling driving experience, consider making this upgrade.
