by

The installation and tuning of the Garrett Performance WRX Front Mount Intercooler System is an essential upgrade for enthusiasts looking to enhance their vehicle’s performance. This guide will cover the necessary steps for installation and tuning to ensure optimal performance.

Understanding the Benefits of a Front Mount Intercooler

A front mount intercooler (FMIC) offers several advantages over traditional top mount intercoolers (TMIC). Here are some key benefits:

  • Improved Cooling Efficiency: FMICs provide better airflow and cooling, reducing intake temperatures.
  • Increased Power Output: Cooler air allows for more efficient combustion, resulting in higher horsepower.
  • Enhanced Reliability: Lower temperatures can lead to decreased engine knock and improved reliability.

Tools and Materials Needed

Before starting the installation, gather the following tools and materials:

  • Tools:
    • Socket set
    • Wrenches
    • Screwdrivers
    • Torque wrench
    • Cutting tool (if necessary)
  • Materials:
    • Garrett Performance WRX Front Mount Intercooler Kit
    • Silicone hoses
    • Clamps
    • Intercooler mounting brackets

Installation Steps

Step 1: Preparation

Begin by preparing your vehicle for installation:

  • Park the vehicle on a flat surface.
  • Disconnect the battery to avoid any electrical issues.
  • Remove the front bumper for access to the stock intercooler.

Step 2: Remove the Stock Intercooler

Carefully remove the stock intercooler:

  • Detach the intake and outlet hoses from the stock intercooler.
  • Unbolt the intercooler from its mounting points.
  • Remove the stock intercooler from the vehicle.

Step 3: Install the Garrett Performance FMIC

Now, install the Garrett Performance FMIC:

  • Position the FMIC in place using the provided mounting brackets.
  • Secure the intercooler with bolts, ensuring it is firmly mounted.
  • Attach the silicone hoses to the inlet and outlet of the FMIC.

Step 4: Reinstall the Front Bumper

With the FMIC installed, it’s time to reinstall the front bumper:

  • Carefully align the bumper with the intercooler.
  • Reconnect any electrical connections that were disconnected.
  • Secure the bumper with its original screws and clips.

Step 5: Final Checks

Before starting the vehicle, perform the following checks:

  • Ensure all hoses and clamps are tight and secure.
  • Check for any clearance issues with the FMIC.
  • Reconnect the battery.

Tuning the Vehicle

After installation, tuning the vehicle is crucial to maximize the benefits of the FMIC:

Step 1: Use a Tuning Software

Utilize a tuning software compatible with your WRX, such as:

  • ECUtek
  • Accessport
  • Open Source Tuning

Step 2: Adjust Fuel Maps

Modify the fuel maps to accommodate the increased airflow:

  • Increase fuel delivery to match the new intercooler setup.
  • Monitor air-fuel ratios for optimal performance.

Step 3: Monitor Performance

After tuning, it’s important to monitor the vehicle’s performance:

  • Use a wideband O2 sensor to check air-fuel ratios.
  • Track boost levels to ensure they are within safe limits.
  • Conduct test drives to evaluate performance improvements.

Conclusion

Installing and tuning the Garrett Performance WRX Front Mount Intercooler System can significantly enhance your vehicle’s performance. By following the steps outlined in this guide, you can ensure a successful installation and optimal tuning for improved power and efficiency.
