The Mitsubishi Lancer Evolution X, known for its performance and tuning potential, can greatly benefit from a cold air intake system. This modification is not only cost-effective but also enhances throttle response and can add up to 15 horsepower. In this guide, we will walk you through the installation process of a cold air intake for the Evo X, ensuring that you can achieve these performance gains with ease.
Why Upgrade to a Cold Air Intake?
A cold air intake (CAI) system replaces the factory air intake system, allowing for better airflow to the engine. Here are a few reasons why you should consider this upgrade:
- Improved Throttle Response: A CAI allows the engine to breathe better, leading to quicker throttle response.
- Increased Horsepower: Many users report gains of up to 15 hp with a CAI installed.
- Enhanced Engine Sound: A CAI can give your Evo X a more aggressive engine note.
- Cost-Effective Mod: For under $300, you can achieve significant performance improvements.
Tools and Materials Needed
Before starting the installation, ensure you have the following tools and materials:
- Cold Air Intake Kit
- Socket Set
- Ratchet Wrench
- Flathead Screwdriver
- Phillips Screwdriver
- Torque Wrench
- Shop Towels
- Safety Glasses
Step-by-Step Installation Guide
Step 1: Preparation
Start by parking your Evo X on a flat surface and engaging the parking brake. Allow the engine to cool down completely before beginning the installation. Gather all tools and materials, and put on your safety glasses.
Step 2: Remove the Factory Intake
Open the hood and locate the factory air intake system. Follow these steps to remove it:
- Disconnect the negative battery terminal to prevent any electrical issues.
- Unclip and remove the air intake duct from the throttle body.
- Unscrew and detach the airbox from its mounting points.
- Carefully pull out the factory air filter and intake assembly.
Step 3: Install the Cold Air Intake
Now that the factory intake is removed, it’s time to install the new cold air intake:
- Place the new air filter into the designated area of the cold air intake kit.
- Attach the intake tube to the throttle body using the provided clamps.
- Secure the intake system to the vehicle’s mounting points.
- Ensure all connections are tight and there are no air leaks.
Step 4: Reconnect the Battery and Test
After the installation is complete, reconnect the negative battery terminal. Start the engine and let it idle for a few minutes. Listen for any unusual sounds and check for any leaks around the intake area.
Post-Installation Tips
Once the cold air intake is installed, consider the following tips to maximize performance:
- Regular Maintenance: Clean the air filter regularly to ensure optimal airflow.
- Monitor Engine Performance: Keep an eye on any changes in engine performance or check engine lights.
- Consider Tuning: For even greater performance gains, consider a tune to complement your new intake.
Conclusion
Installing a cold air intake on your Evo X is a straightforward process that can yield significant performance improvements. With the right tools and a little bit of time, you can enhance your vehicle’s throttle response and add up to 15 horsepower for under $300. Enjoy the benefits of your upgrade and the enhanced driving experience!
