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

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 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.
