Tools and Materials Needed
- Skunk2 Pro Series Intake Manifold
- Socket set
- Torque wrench
- Screwdrivers (flathead and Phillips)
- Gasket scraper
- New intake manifold gasket
- Throttle body cleaner
- Vacuum hose (if needed)
- Shop towels
Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials to make the process smoother.
Disconnect the Battery
Begin by disconnecting the negative terminal of the battery. This step is crucial to prevent any electrical shorts during the installation process.
Remove the Engine Cover
Next, remove the engine cover by unscrewing the bolts that hold it in place. This will give you access to the intake manifold.
Removing the Stock Intake Manifold
With the engine cover removed, you can now proceed to take off the stock intake manifold.
Disconnect All Hoses and Sensors
Carefully disconnect all hoses, electrical connectors, and sensors attached to the stock intake manifold. Make sure to label them if necessary to ensure proper reinstallation.
Unbolt the Stock Intake Manifold
Using your socket set, unbolt the stock intake manifold from the engine. Keep track of the bolts as you will need them for the new manifold.
Remove the Old Gasket
Once the manifold is removed, use a gasket scraper to clean off any remnants of the old gasket from the engine surface. This step is essential for a proper seal with the new manifold.
Installing the Skunk2 Pro Series Intake Manifold
Now that the stock manifold is removed, it’s time to install the Skunk2 Pro Series Intake Manifold.
Position the New Gasket
Place the new intake manifold gasket onto the engine. Ensure it is aligned properly with all bolt holes.
Install the Skunk2 Intake Manifold
Carefully position the Skunk2 Pro Series Intake Manifold over the gasket and align it with the bolt holes. Once in place, hand-tighten the bolts to secure it.
Torque the Bolts
Using a torque wrench, tighten the intake manifold bolts to the manufacturer’s specifications. This step is critical to ensure a proper seal and prevent leaks.
Reconnect Hoses and Sensors
Reconnect all hoses and sensors that were disconnected earlier. Double-check to ensure everything is connected properly.
Final Steps
After installing the new manifold, there are a few final steps to complete the installation.
Reinstall the Engine Cover
Replace the engine cover by screwing it back into place. Ensure it is secured properly to avoid any rattling.
Reconnect the Battery
Reconnect the negative terminal of the battery. This will restore power to the vehicle.
Start the Engine
Start the engine and let it idle for a few minutes. Check for any leaks or unusual noises. If everything sounds good, you have successfully installed the Skunk2 Pro Series Intake Manifold!
