What You Will Need
- AEM Boost Leak Tester Kit
- Socket set
- Wrenches
- Vacuum pump (optional)
- Safety goggles
- Shop towels
Before starting the installation, ensure you have all the necessary tools and equipment ready. This will help streamline the process and avoid interruptions.
Preparation Steps
Follow these preparation steps to ensure a smooth installation:
- Park your Subaru WRX on a flat surface and engage the parking brake.
- Disconnect the battery to prevent any electrical issues during installation.
- Remove any engine covers or components that may obstruct access to the intake system.
Installation Process
Step 1: Locate the Intake System
Identify the intake system of your Subaru WRX, which includes the throttle body and the intake manifold. This is where the boost leak tester will be connected.
Step 2: Remove the Intake Hose
Using your socket set, carefully loosen and remove the clamps securing the intake hose to the throttle body. Gently pull the hose off and set it aside.
Step 3: Connect the Boost Leak Tester
Take the AEM Boost Leak Tester and connect it to the throttle body where the intake hose was previously attached. Ensure a snug fit to avoid any air leaks.
Step 4: Seal the System
Using the provided sealing plugs, block off any other openings in the intake system to ensure that the pressure is maintained during the testing process.
Step 5: Apply Pressure
Using a vacuum pump or the manual pump included in the AEM kit, apply pressure to the intake system. Monitor the pressure gauge to ensure it reaches the desired level.
Step 6: Inspect for Leaks
Carefully inspect all connections and components for any signs of air leaks. If the pressure drops quickly, you may need to check for loose clamps or damaged hoses.
Post-Installation Steps
Once the testing is complete, follow these steps to finalize the installation:
- Release the pressure from the system and disconnect the boost leak tester.
- Reattach the intake hose securely to the throttle body.
- Reconnect any components or engine covers that were removed during the installation.
- Reconnect the battery.
Testing and Validation
After completing the installation, it’s important to validate your results:
- Start your Subaru WRX and let it idle for a few minutes.
- Monitor the engine performance and check for any unusual sounds.
- Take the vehicle for a test drive to ensure everything is functioning smoothly.
Troubleshooting Common Issues
If you encounter issues during or after installation, consider the following troubleshooting tips:
- Check for any loose connections or damaged hoses.
- Ensure that all sealing plugs are properly installed.
- Re-evaluate the pressure levels applied during testing.
