Wrx Front Mount Intercooler Installation Guide: Step-by-step for 300, 400, and 500+ Hp Builds

The installation of a front mount intercooler (FMIC) is a crucial upgrade for WRX enthusiasts looking to enhance performance. This guide will walk you through the step-by-step process of installing an FMIC suitable for builds producing 300, 400, and even 500+ horsepower.

Tools and Materials Needed

  • Front mount intercooler kit
  • Socket set
  • Wrench set
  • Screwdriver set
  • Hose clamps
  • Silicone hoses
  • Zip ties
  • Drill with bits (if necessary)
  • Heat-resistant tape

Preparation Steps

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

1. Remove the Front Bumper

Start by removing the front bumper to access the factory intercooler. This typically involves unscrewing several bolts and clips. Carefully detach the bumper and set it aside.

2. Disconnect the Factory Intercooler

Next, disconnect the piping from the factory intercooler. Use your socket set to remove the bolts securing the intercooler to the vehicle. Make sure to also remove any associated hoses and clamps.

Installing the Front Mount Intercooler

With the factory intercooler removed, it’s time to install the front mount intercooler. Follow these steps carefully to ensure a proper fit.

1. Position the Intercooler

Position the new front mount intercooler in front of the vehicle’s radiator. Make sure it is level and centered. You may need to adjust the mounting brackets to achieve the perfect fit.

2. Secure the Intercooler

Once positioned, secure the intercooler using the provided mounting brackets and bolts. Ensure everything is tight and secure to prevent movement during operation.

3. Connect the Piping

Using the silicone hoses and clamps, connect the piping from the turbo to the intercooler and from the intercooler to the throttle body. Ensure all connections are tight and leak-free.

Final Steps

With the intercooler installed and the piping connected, it’s time to reassemble the front of the vehicle.

1. Reinstall the Front Bumper

Carefully reattach the front bumper, ensuring that all clips and bolts are secured. Check that the intercooler is not obstructing any components.

2. Check for Leaks

Before starting the engine, double-check all connections for leaks. It’s crucial to ensure everything is sealed properly to avoid performance issues.

3. Start the Engine

Start the engine and let it idle for a few minutes. Monitor the intercooler and piping for any signs of leaks or issues. If everything looks good, take your WRX for a test drive.

Tuning Considerations

After installing a front mount intercooler, it’s essential to consider tuning your WRX to maximize performance. A proper tune will ensure that your engine runs efficiently with the new intercooler setup.

1. Consult a Professional Tuner

Consulting a professional tuner can provide valuable insights and adjustments tailored to your specific setup and power goals.

2. Monitor Engine Parameters

After tuning, monitor key engine parameters such as boost levels, air-fuel ratios, and temperatures to ensure optimal performance and reliability.

Conclusion

Installing a front mount intercooler on your WRX can significantly enhance performance, especially for high horsepower builds. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved cooling efficiency and power delivery.
