The Subaru WRX is a high-performance vehicle known for its rally-inspired design and impressive speed. To enhance its capabilities, many enthusiasts turn to aftermarket modifications, one of which is the intercooler. In this article, we will evaluate the performance gains of the Treadstone 27x12x4 intercooler on Subaru WRX models.
Understanding Intercoolers
Intercoolers are crucial components in turbocharged engines, as they help reduce the temperature of the air entering the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to increased power output. The Treadstone 27x12x4 intercooler is designed to optimize this process for Subaru WRX models.
Specifications of the Treadstone 27x12x4 Intercooler
The Treadstone 27x12x4 intercooler features a large core size that contributes to its efficiency. Here are some key specifications:
- Core Size: 27 inches x 12 inches x 4 inches
- Inlet/Outlet Size: 2.5 inches
- Material: Bar and plate construction for durability
- Weight: Lightweight for easy installation
Installation Process
Installing the Treadstone intercooler on a Subaru WRX requires some mechanical knowledge. Here is a brief overview of the installation process:
- Gather necessary tools: socket set, wrenches, and clamps.
- Remove the stock intercooler and piping.
- Install the Treadstone intercooler in the same location.
- Reattach the piping and ensure all connections are secure.
- Check for any leaks and start the engine to test functionality.
Performance Gains
After installation, many Subaru WRX owners report noticeable performance gains. The benefits of the Treadstone 27x12x4 intercooler include:
- Lower intake air temperatures, resulting in improved engine efficiency.
- Increased horsepower and torque, especially during high boost situations.
