Tools and Materials Needed
- AEM Catch Can Kit

Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials to streamline the process.
Step 1: Locate the PCV System
Open the hood and locate the Positive Crankcase Ventilation (PCV) system. This is typically found on the engine cover. Familiarize yourself with the layout to identify the connections for the catch can.
Step 2: Remove the Engine Cover
Using a ratchet and socket, carefully remove the bolts securing the engine cover. Set the cover aside in a safe location.
Step 3: Disconnect the PCV Hose
Gently disconnect the PCV hose from the intake manifold. Be cautious not to damage the hose or fittings during this process.
Step 4: Install the AEM Catch Can
Choose a suitable location for the catch can, typically near the intake manifold. Use the provided mounting hardware to secure the catch can in place. Ensure it is stable and will not move during operation.
Step 5: Connect the Hoses
Using the provided hoses, connect one end to the PCV port on the catch can and the other end to the intake manifold. Ensure the connections are tight to prevent any leaks.
Step 6: Secure the Catch Can
Once the hoses are connected, use zip ties or additional mounting hardware to secure the catch can and prevent movement. Double-check all connections for tightness.
Step 7: Reinstall the Engine Cover
Carefully place the engine cover back onto the engine bay. Secure it with the bolts you removed earlier. Ensure everything is aligned properly.
Step 8: Final Checks
Before starting the engine, double-check all connections and ensure there are no loose parts. Make sure the catch can is securely mounted and all hoses are properly connected.
Step 9: Start the Engine
Start the engine and let it idle for a few minutes. Check for any leaks around the catch can and hoses. If everything looks good, take your Civic Si for a test drive.
Maintenance Tips
Regular maintenance of your AEM catch can is essential for optimal performance. Here are some tips:
- Check the catch can every 500 miles for fluid levels.
- Empty the catch can as needed, ideally every oil change.
- Inspect hoses for wear or damage regularly.
- Ensure all connections remain tight.
Conclusion
Installing an AEM catch can on your 2015-2019 Honda Civic Si is a straightforward process that can enhance engine performance. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved engine health.
