Preparation Steps

Before starting 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.

Safety First

Always wear safety glasses and gloves while working on your vehicle. This will protect you from any debris or sharp edges.

Step-by-Step Installation

Step 1: Remove the Engine Cover

Using a socket set, remove the bolts securing the engine cover. Carefully lift it off and set it aside.

Step 3: Install the New TMIC

Position the new Perrin or Cobb TMIC in place. Make sure it aligns properly with the mounting points. Secure the intercooler using the provided bolts and torque them to the manufacturer’s specifications.

Step 4: Reconnect the Hoses

Reconnect the hoses to the new intercooler. Ensure that the hose clamps are tightened securely to prevent any boost leaks.

Step 5: Reinstall the Engine Cover

Once everything is securely in place, reinstall the engine cover by reversing the removal process. Tighten the bolts to ensure it is secure.

Post-Installation Checks

After the installation, it’s essential to perform a few checks to ensure everything is functioning correctly.

Check for Boost Leaks

Start the engine and let it idle. Listen for any hissing sounds that could indicate a boost leak. If you hear any, double-check your hose connections and clamps.

Monitor Engine Temperature

Take the WRX for a short test drive. Monitor the engine temperature and ensure that it remains within the normal range. If you notice any overheating, stop and check your installation.
