The Subaru WRX is known for its turbocharged performance and rally-inspired design. One of the most effective upgrades for enhancing the power and efficiency of your WRX is the installation of a larger intercooler. In this article, we will focus on upgrading to a 33-inch core intercooler, discussing the installation process and the potential power gains.
Why Upgrade to a 33-Inch Core Intercooler?
Upgrading to a 33-inch core intercooler can significantly improve the performance of your Subaru WRX. Here are some reasons why this upgrade is beneficial:
- Increased Cooling Efficiency: A larger core allows for better heat dissipation, which helps maintain optimal intake temperatures.
- Improved Power Output: Cooler air is denser, allowing for more air and fuel to enter the engine, leading to increased horsepower.
- Enhanced Reliability: Reducing intake temperatures can prevent engine knock and prolong engine life.
Installation Process
Installing a 33-inch core intercooler on your Subaru WRX requires some mechanical skills and tools. Below is a step-by-step guide to help you through the installation process.
Tools and Materials Needed
- 33-inch core intercooler kit
- Socket set
- Wrenches
- Phillips and flathead screwdrivers
- Hose clamps
- Intercooler piping (if necessary)
- Thermal paste (optional)
Step-by-Step Installation
Follow these steps to install your new intercooler:
- Step 1: Begin by disconnecting the battery to ensure safety.
- Step 2: Remove the front bumper by unscrewing the necessary bolts and clips.
- Step 3: Take off the factory intercooler by disconnecting the piping and any attached sensors.
- Step 4: Install the new 33-inch core intercooler in the same position as the factory unit.
- Step 5: Reconnect the piping and ensure all hose clamps are tight.
- Step 6: Reinstall the front bumper carefully, ensuring all clips and bolts are secure.
- Step 7: Reconnect the battery and start the engine to check for leaks.
Power Gains from Upgrading
After installing a 33-inch core intercooler, many Subaru WRX owners report noticeable power gains. Here’s what you can expect:
- Increased Horsepower: Upgrading the intercooler can add anywhere from 20 to 50 additional horsepower, depending on other modifications.
- Improved Torque: Better airflow can lead to increased torque, enhancing acceleration.
- Better Throttle Response: Cooler intake air results in improved throttle response, making the car feel more responsive.
Conclusion
Upgrading to a 33-inch core intercooler is a worthwhile investment for any Subaru WRX enthusiast looking to enhance their vehicle’s performance. With improved cooling efficiency, increased power output, and better reliability, this modification can elevate your driving experience. Follow the installation steps carefully, and enjoy the benefits of your upgraded intercooler!
