The Subaru WRX is a beloved vehicle among car enthusiasts, known for its performance and rally heritage. One of the key components that can significantly enhance its power and efficiency is the intercooler. In this article, we will explore the benefits of upgrading to the ETS 27x12x4 intercooler and how it can maximize power for your Subaru WRX.
Understanding Intercoolers
An intercooler serves the crucial function of cooling the air that enters the engine after it has been compressed by the turbocharger. Cooler air is denser, which means it contains more oxygen, allowing for better combustion and increased power. Upgrading to a larger intercooler, such as the ETS 27x12x4, can provide significant performance gains.
Key Features of the ETS 27x12x4 Intercooler
- Size: The 27x12x4 dimensions allow for greater airflow and cooling capacity.
- Core Design: Features a bar and plate design that enhances heat dissipation.
- Durability: Constructed from high-quality materials to withstand high performance demands.
- Easy Installation: Designed for a straightforward installation process on the WRX.
Performance Gains with the ETS Intercooler
Upgrading to the ETS 27x12x4 intercooler can lead to several performance benefits:
- Increased Horsepower: Users have reported gains of up to 20-30 horsepower with proper tuning.
- Improved Torque: Enhanced torque delivery, especially in the mid-range RPMs.
- Lower Intake Temperatures: Significant reduction in intake air temperatures, leading to more efficient combustion.
- Enhanced Throttle Response: Quicker throttle response due to improved airflow.
Installation Process
Installing the ETS 27x12x4 intercooler can be done with basic tools and mechanical knowledge. Here’s a brief overview of the installation steps:
- Remove the factory intercooler and associated piping.
- Install the ETS intercooler using the provided mounting hardware.
- Reconnect the intake and charge piping.
- Ensure all connections are tight and secure.
