Installing an intercooler on your WRX can significantly enhance your vehicle’s performance. This guide provides a step-by-step approach to installing both OEM and aftermarket intercoolers.
Understanding Intercoolers
An intercooler is essential for turbocharged engines as it cools the intake air, increasing density and improving performance. The WRX models benefit greatly from upgraded intercoolers.
Tools and Materials Needed
- Socket set
- Torque wrench
- Flathead and Phillips screwdrivers
- Intercooler (OEM or aftermarket)
- Hoses and clamps
- Coolant (if necessary)
- Shop towels
Preparation Steps
Before starting the installation, ensure you have all tools and materials ready. Park your WRX on a level surface and allow the engine to cool completely.
Step 1: Remove the Front Bumper
To access the intercooler, you need to remove the front bumper. Start by unscrewing the bolts located under the hood and along the wheel wells. Carefully pull the bumper away from the vehicle.
Step 2: Disconnect the Existing Intercooler
Locate the existing intercooler and disconnect the hoses attached to it. Use a flathead screwdriver to loosen the clamps. Be careful as some coolant may spill out.
Step 3: Remove the Old Intercooler
Once the hoses are disconnected, unbolt the intercooler from its mounting points. Lift it out carefully and set it aside.
Step 4: Install the New Intercooler
Position the new intercooler in place and secure it with the mounting bolts. Make sure it fits snugly and does not obstruct any other components.
Step 5: Connect the Hoses
Reconnect the hoses to the new intercooler. Ensure that the clamps are tightened properly to prevent any leaks.
Step 6: Reattach the Front Bumper
Carefully reattach the front bumper by aligning it with the mounting points. Secure it with the bolts you removed earlier.
Step 7: Final Checks
Before starting the engine, double-check all connections and ensure everything is tightly secured. Check the coolant level and top off if necessary.
Aftermarket Intercooler Options
Aftermarket intercoolers can provide better performance than OEM options. Here are a few popular aftermarket intercoolers for the WRX:
- Process West Verticooler
- Grimmspeed Top Mount Intercooler
- COBB Tuning Front Mount Intercooler
Conclusion
Installing an intercooler on your WRX can be a rewarding project that enhances your vehicle’s performance. Whether you choose an OEM or aftermarket option, following these steps will help ensure a successful installation.
