Installing a 24-inch Wrx Front Mount Intercooler: Boosting Intake Temps and Power Output

by

Installing a front mount intercooler is a popular modification for Subaru WRX owners looking to enhance their vehicle’s performance. A 24-inch front mount intercooler can significantly boost intake temperatures and power output, making it an attractive upgrade for those seeking more from their turbocharged engines.

Benefits of a Front Mount Intercooler

A front mount intercooler (FMIC) serves several purposes that contribute to improved engine performance:

  • Lower Intake Temperatures: FMICs provide more surface area for air cooling, reducing the temperature of the air entering the engine.
  • Increased Power Output: Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to higher power levels.
  • Improved Throttle Response: A well-designed FMIC can enhance throttle response by maintaining optimal air temperatures.
  • Better Performance in High-Load Conditions: FMICs perform better under high boost conditions, making them ideal for track or performance driving.

Tools and Materials Needed

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

  • Socket set
  • Wrenches
  • Screwdrivers
  • Intercooler piping kit
  • 24-inch front mount intercooler
  • Hoses and clamps
  • Heat-resistant tape
  • Optional: Silicone couplers

Step-by-Step Installation Guide

Step 1: Prepare Your Vehicle

Start by parking your WRX on a flat surface and ensuring the engine is cool. Disconnect the battery to prevent any electrical issues during the installation.

Step 2: Remove the Front Bumper

To access the stock intercooler, you will need to remove the front bumper. This typically involves:

  • Unscrewing the screws and clips that hold the bumper in place.
  • Carefully pulling the bumper away from the vehicle.
  • Disconnecting any fog light or sensor wiring.

Step 3: Remove the Stock Intercooler

Once the bumper is removed, locate the stock intercooler:

  • Disconnect the hoses attached to the stock intercooler.
  • Unbolt the intercooler from its mounting points.
  • Carefully remove the intercooler from the engine bay.

Step 4: Install the New Front Mount Intercooler

With the stock intercooler removed, it’s time to install the new 24-inch front mount intercooler:

  • Position the FMIC in the desired location, ensuring it fits properly.
  • Secure the FMIC using the provided mounting hardware.
  • Connect the new intercooler piping, ensuring all connections are tight and leak-free.

Step 5: Reinstall the Front Bumper

After the intercooler is securely in place, reinstall the front bumper:

  • Reconnect any fog light or sensor wiring.
  • Align the bumper and secure it with screws and clips.

Step 6: Reconnect the Battery and Test

Once everything is back in place, reconnect the battery:

  • Start the engine and check for any leaks.
  • Ensure that the intercooler is functioning properly.
  • Take the car for a test drive to experience the enhanced performance.

Conclusion

Installing a 24-inch front mount intercooler on your WRX is a straightforward process that can yield significant performance benefits. By following this guide, you can boost your vehicle’s intake temperatures and power output, leading to a more exhilarating driving experience.
