by

The WRX is a beloved model among car enthusiasts, especially those who enjoy modifying their vehicles for improved performance. One of the most significant upgrades you can make to your 2020+ Subaru WRX is installing a front mount intercooler (FMIC). This guide will walk you through the installation process for two popular FMIC options: the Mishimoto and PWR models.

Why Upgrade to a Front Mount Intercooler?

Upgrading to a front mount intercooler provides several benefits, including:

  • Improved Cooling Efficiency: FMICs allow for better airflow and cooling, which can lead to increased horsepower and torque.
  • Reduced Intake Temperatures: Lower intake temperatures help prevent engine knock and improve overall performance.
  • Enhanced Reliability: A high-quality intercooler can improve the longevity of your engine components.

Tools and Materials Needed

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

  • Socket set
  • Wrenches
  • Torque wrench
  • Flathead screwdriver
  • Phillips screwdriver
  • Cutting tool (if necessary)
  • FMIC kit (Mishimoto or PWR)
  • Silicone couplers
  • Hoses and clamps

Preparation for Installation

Follow these steps to prepare your vehicle for the intercooler installation:

  • Park on a Level Surface: Ensure your WRX is parked on a flat surface to make the installation easier.
  • Disconnect the Battery: To prevent any electrical issues, disconnect the negative terminal of the battery.
  • Remove the Front Bumper: Carefully remove the front bumper by unscrewing the necessary bolts and clips.

Installing the Mishimoto Front Mount Intercooler

Follow these steps to install the Mishimoto FMIC:

  • Remove the Stock Intercooler: Unscrew the bolts securing the factory intercooler and disconnect the piping.
  • Install the Mishimoto FMIC: Position the new intercooler in place and secure it using the provided hardware.
  • Connect the Piping: Use the silicone couplers to connect the piping to the new intercooler.
  • Tighten All Clamps: Ensure all clamps are tight to prevent any boost leaks.
  • Reinstall the Front Bumper: Carefully put the bumper back on and secure it with the bolts and clips.

Installing the PWR Front Mount Intercooler

If you choose the PWR FMIC, follow these steps:

  • Remove the Stock Intercooler: Just like with the Mishimoto, start by removing the factory intercooler and piping.
  • Position the PWR FMIC: Align the PWR intercooler in place and use the included hardware to secure it.
  • Attach the Piping: Connect the silicone couplers and piping to the PWR intercooler.
  • Tighten All Connections: Ensure everything is secure to avoid any leaks.
  • Reattach the Front Bumper: Put the bumper back on and fasten it using the bolts and clips.

Final Steps

After installing either the Mishimoto or PWR intercooler, follow these final steps:

  • Reconnect the Battery: Reattach the negative terminal to the battery.
  • Check for Leaks: Start the engine and inspect for any boost leaks in the system.
  • Take a Test Drive: Go for a test drive to ensure everything is functioning correctly and to feel the performance improvements.

Conclusion

Upgrading to a front mount intercooler is a fantastic way to enhance the performance of your 2020+ Subaru WRX. Whether you choose the Mishimoto or PWR model, following this installation guide will help ensure a successful upgrade. Enjoy your improved driving experience!
