The AEM Cold Air Intake system is a popular modification among Mazdaspeed 3 enthusiasts looking to increase performance. This installation guide will walk you through the steps to successfully install the AEM Cold Air Intake on your Mazdaspeed 3, potentially gaining up to 15 rear wheel horsepower for an investment of around $350.
Why Choose AEM Cold Air Intake?
AEM is known for producing high-quality performance parts. The cold air intake system is designed to draw cooler air from outside the engine bay, which can lead to better combustion and increased horsepower. Here are some benefits of choosing the AEM Cold Air Intake:
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
- Easy installation process
Tools and Materials Needed
Before you begin the installation, gather the following tools and materials:
- AEM Cold Air Intake Kit
- Socket set (10mm, 12mm)
- Flathead screwdriver
- Phillips screwdriver
- Torque wrench
- Zip ties
- Safety glasses
- Gloves
Step-by-Step Installation Guide
Step 1: Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface. Turn off the engine and allow it to cool down. Open the hood and disconnect the negative battery terminal to prevent any electrical issues during installation.
Step 2: Remove the Stock Intake System
Begin by removing the stock intake system. Follow these steps:
- Disconnect the mass airflow sensor (MAF) connector.
- Loosen the hose clamp on the throttle body using a flathead screwdriver.
- Remove the two bolts securing the airbox using a 10mm socket.
- Lift the airbox out of the engine bay and remove the intake tube.
Step 3: Install the AEM Cold Air Intake
Now it’s time to install the AEM Cold Air Intake. Follow these steps:
- Place the AEM air filter onto the intake tube and secure it with the provided hose clamp.
- Install the intake tube into the throttle body and secure it with the hose clamp.
- Position the air filter in the designated area, ensuring it is not touching any hot engine components.
- Use zip ties to secure any loose wiring or components away from the intake system.
Step 4: Reconnect the MAF Sensor
Reconnect the mass airflow sensor by plugging it back into the connector. Ensure it is securely fastened to prevent any air leaks.
Step 5: Final Checks and Reconnect Battery
Before closing the hood, double-check all connections and ensure everything is tight. Reconnect the negative battery terminal and start the engine. Listen for any unusual sounds and check for any air leaks around the intake.
Performance Gains and Tuning
After installation, many Mazdaspeed 3 owners report noticeable performance gains. While the AEM Cold Air Intake alone can provide up to 15 rear wheel horsepower, it is recommended to pair it with a tune for optimal performance. A proper tune can help maximize the benefits of the intake system and ensure your engine runs efficiently.
Maintenance Tips
To keep your AEM Cold Air Intake performing at its best, follow these maintenance tips:
- Inspect the air filter regularly for dirt and debris.
- Clean the air filter as needed using an AEM cleaning kit.
- Check all connections and clamps periodically for tightness.
- Monitor engine performance and check for any warning lights on the dashboard.
Conclusion
Installing an AEM Cold Air Intake on your Mazdaspeed 3 is a straightforward process that can yield impressive performance gains. For around $350, you can enhance your driving experience with increased horsepower and improved throttle response. By following this guide and performing regular maintenance, you can enjoy the benefits of your new intake system for years to come.
