The Subaru WRX is a performance-oriented vehicle that has captured the hearts of many enthusiasts. One of the most effective upgrades for enhancing its performance is the installation of a top mount intercooler (TMIC). This guide will walk you through the process of installing a Wrx top mount intercooler specifically for the Subaru WRX models from 2015 to 2023.
Why Upgrade to a Top Mount Intercooler?
Upgrading to a top mount intercooler can provide several benefits for your Subaru WRX, including:
- Improved Cooling Efficiency: A larger intercooler can reduce intake temperatures, leading to better performance.
- Increased Power Output: Cooler air allows for more aggressive tuning and increased horsepower.
- Enhanced Throttle Response: Improved airflow can lead to quicker throttle response and better overall drivability.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Socket set (10mm, 12mm, 14mm sockets)
- Ratchet and extensions
- Torque wrench
- Flathead screwdriver
- Phillips screwdriver
- Intercooler installation kit (if applicable)
- New clamps (if necessary)
- Shop towels
Step-by-Step Installation Process
Step 1: Preparation
Before beginning the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative terminal of the battery to prevent any electrical issues during the process.
Step 2: Remove the Engine Cover
Using a socket wrench, remove the bolts securing the engine cover. Carefully lift the cover off and set it aside.
Step 3: Disconnect the Existing Intercooler
Locate the stock intercooler. Start by disconnecting the inlet and outlet pipes. Use a flathead screwdriver to loosen the clamps and gently pull the pipes off. Be cautious not to damage any surrounding components.
Next, remove the bolts securing the intercooler to the mounting brackets. Carefully lift the intercooler out of the engine bay and set it aside.
Step 4: Install the New Top Mount Intercooler
Position the new top mount intercooler in place, aligning it with the mounting brackets. Secure it using the bolts you previously removed. Make sure to torque the bolts to the manufacturer’s specifications.
Step 5: Reconnect the Inlet and Outlet Pipes
Reconnect the inlet and outlet pipes to the new intercooler. Ensure that the clamps are tightened properly to prevent any boost leaks. Double-check the connections to make sure everything is secure.
Step 6: Reinstall the Engine Cover
Place the engine cover back onto the engine bay and secure it with the bolts. Make sure it sits properly without any obstructions.
Step 7: Reconnect the Battery
Reconnect the negative terminal of the battery. Ensure it’s tightened securely to prevent any electrical issues.
Testing Your Installation
After completing the installation, it’s important to test the vehicle to ensure everything is functioning properly. Start the engine and check for any leaks around the intercooler and connections. Take the car for a short drive and monitor the performance. Look for improvements in throttle response and overall power delivery.
Maintenance Tips
To keep your new top mount intercooler functioning optimally, consider the following maintenance tips:
- Regularly check for leaks and ensure all clamps are tight.
- Inspect the intercooler for any signs of damage or corrosion.
- Clean the intercooler periodically to remove any debris or dirt that may affect performance.
Conclusion
Upgrading to a top mount intercooler is a worthwhile modification for Subaru WRX owners looking to enhance performance. By following this installation guide, you can successfully install your new intercooler and enjoy the benefits of improved cooling and power. Happy driving!
