Tools and Materials Needed
- Skunk2 MegaPower Intake Manifold
- Socket set
- Torque wrench
- Screwdrivers (flathead and Phillips)
- Ratchet extension
- Gasket scraper
- New intake manifold gasket
- Throttle body cleaner
- Shop towels
- Safety glasses
Preparation
Before starting the installation, ensure you have all tools and materials ready. Additionally, park your Honda Civic Si on a flat surface and allow the engine to cool down completely.
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 to expose the intake manifold.
Step 2: Disconnect the Throttle Body and Other Components
Detach the throttle body by removing the bolts with a socket wrench. Also, disconnect any sensors and vacuum lines attached to the intake manifold. Make sure to label them for easier reinstallation.
Step 3: Remove the Old Intake Manifold
Unscrew the bolts holding the old intake manifold in place. Carefully lift it off the engine, ensuring no debris falls into the intake ports. Use a gasket scraper to remove any remnants of the old gasket from the engine surface.
Step 4: Install the New Intake Manifold
Place the new Skunk2 MegaPower Intake Manifold onto the engine. Make sure it aligns properly with the mounting holes. Install the new intake manifold gasket before securing the manifold with bolts.
Step 5: Reconnect the Throttle Body and Components
Reattach the throttle body, ensuring it is properly aligned. Reconnect all sensors and vacuum lines that were previously disconnected. Refer to your labels to ensure accuracy.
Step 6: Torque Specifications
Using a torque wrench, tighten the intake manifold bolts to the manufacturer’s specifications. This step is crucial to prevent any leaks or issues during operation.
Step 7: Reinstall the Engine Cover
Once everything is secured and connected, place the engine cover back onto the engine. Tighten the bolts to hold it in place.
Step 8: Final Checks and Testing
Before starting the engine, double-check all connections and ensure there are no tools left in the engine bay. Start the engine and listen for any unusual sounds. Check for leaks around the intake manifold.
