Air to Water Intercooler Installation Guide: Upgrading Your Subaru Wrx with Hks and Turbosmart Kits

Upgrading your Subaru WRX with an air to water intercooler can significantly enhance performance and efficiency. This guide will walk you through the installation process using HKS and TurboSmart kits, ensuring you get the most out of your vehicle.

Understanding Air to Water Intercoolers

Air to water intercoolers utilize a liquid coolant to absorb heat from the air compressed by the turbocharger. This method is more efficient than traditional air to air intercoolers, especially in high-performance settings.

Benefits of Upgrading

  • Improved cooling efficiency
  • Reduced intake air temperatures
  • Enhanced horsepower and torque
  • Better performance in extreme conditions

Required Tools and Materials

  • Socket set
  • Wrenches
  • Screwdrivers
  • Coolant hoses
  • HKS or TurboSmart intercooler kit
  • Mounting brackets
  • Zip ties

Preparation Steps

Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials to streamline the process.

Draining the Coolant

Begin by draining the existing coolant from the system. This will prevent spills and make the installation cleaner.

Removing the Stock Intercooler

Disconnect the battery and remove any parts obstructing access to the stock intercooler. Carefully unbolt and remove the stock intercooler, taking note of how it is connected.

Installing the Air to Water Intercooler

With the stock intercooler removed, it’s time to install your new air to water intercooler. Follow the manufacturer’s instructions closely for the best results.

Mounting the Intercooler

Position the intercooler in the designated area and use the provided mounting brackets to secure it in place. Ensure it is level and properly aligned.

Connecting the Coolant Lines

Attach the coolant lines according to the kit instructions. Make sure all connections are tight to prevent leaks.

Reconnecting the Intake System

Reconnect the intake system, ensuring that all clamps and hoses are secure. Double-check that there are no obstructions in the airflow path.

Final Steps

After the intercooler is installed, refill the coolant system with the appropriate mixture. Start the engine and check for any leaks or issues. Allow the engine to reach operating temperature while monitoring the intercooler performance.

Testing and Tuning

Once installed, it’s crucial to test the vehicle to ensure everything is functioning correctly. Consider taking your WRX for a test drive and monitoring the performance closely.

Using a Tuning Software

Utilize tuning software to optimize your vehicle’s performance after the installation. Adjust parameters as needed to match the new intercooler’s capabilities.

Maintenance Tips

To ensure longevity and optimal performance of your air to water intercooler, regular maintenance is essential. Here are some tips:

  • Check coolant levels regularly
  • Inspect for leaks or damage
  • Clean the intercooler to prevent buildup
  • Monitor engine performance and adjust tuning as needed

Conclusion

Upgrading to an air to water intercooler using HKS and TurboSmart kits can significantly improve your Subaru WRX’s performance. By following this guide, you can ensure a successful installation and enjoy the benefits of enhanced cooling efficiency and power.
