If you’re a Subaru WRX owner looking to boost your vehicle’s performance without breaking the bank, installing an intake spacer is a great option. This guide will walk you through the process step-by-step, ensuring you can achieve that extra horsepower with ease.
What is an Intake Spacer?
An intake spacer is a component that sits between the intake manifold and the throttle body. It increases the volume of the intake manifold, allowing for a better air-fuel mixture and improved engine performance. The benefits include:
- Increased horsepower and torque
- Improved throttle response
- Better fuel efficiency
Tools and Materials Needed
Before you start the installation, gather the following tools and materials:
- Intake spacer kit
- Socket set
- Torque wrench
- Ratchet
- Flathead screwdriver
- Phillips screwdriver
- Clean rags
- Engine cleaner (optional)
Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative battery terminal to prevent any electrical issues during installation.
Step 2: Remove the Engine Cover
Using a socket set, remove the bolts securing the engine cover. Carefully lift off the cover and set it aside.
Step 3: Disconnect the Throttle Body
Locate the throttle body and disconnect the electrical connectors. Remove the bolts holding the throttle body in place using your socket set, then carefully pull it away from the intake manifold.
Step 4: Clean the Surfaces
With the throttle body removed, take the time to clean the mating surfaces on both the intake manifold and the throttle body. This ensures a good seal when installing the spacer.
Step 5: Install the Intake Spacer
Position the intake spacer on the intake manifold, aligning it with the bolt holes. Use the provided gaskets to ensure a proper seal. Secure the spacer with the bolts, tightening them to the manufacturer’s specified torque settings.
Step 6: Reattach the Throttle Body
Carefully place the throttle body back onto the intake spacer. Reinstall the bolts and tighten them securely. Reconnect the electrical connectors to the throttle body.
Step 7: Reinstall the Engine Cover
Once everything is reconnected, place the engine cover back on and secure it with the bolts you removed earlier.
Step 8: Reconnect the Battery
Reconnect the negative battery terminal and ensure it is tight. Your installation is now complete!
Testing Your Vehicle
After installation, it’s important to test your vehicle to ensure everything is functioning correctly. Start the engine and let it idle for a few minutes. Pay attention to any unusual noises or warning lights. Take your WRX for a test drive to feel the difference in performance.
Conclusion
Installing an intake spacer on your Subaru WRX is a straightforward process that can lead to noticeable improvements in horsepower and overall performance. With the right tools and a little patience, you can enjoy the benefits of this upgrade without spending a fortune.
