The Mitsubishi Lancer Evolution IX, commonly known as the Evo 9, has become a beloved icon in the world of performance cars. One of the most effective ways to enhance its performance is through intake upgrades. In this article, we will explore the AEM Cold Air Intake system and its impact on power improvements for the Evo 9.
Understanding Cold Air Intakes
A cold air intake (CAI) system is designed to draw cooler air into the engine compared to the stock intake system. Cooler air is denser, which means it contains more oxygen. This increased oxygen availability allows for better combustion and, ultimately, more power. The AEM Cold Air Intake system is a popular choice among Evo 9 enthusiasts for its quality and performance benefits.
Benefits of the AEM Cold Air Intake
- Increased Horsepower: The AEM Cold Air Intake can provide a significant increase in horsepower, often in the range of 10-20 additional horsepower depending on other modifications.
- Improved Throttle Response: With better airflow, the engine can respond more quickly to throttle inputs, enhancing the driving experience.
- Enhanced Engine Sound: The AEM intake produces a more aggressive engine sound, adding to the overall performance feel of the Evo 9.
- Easy Installation: The AEM Cold Air Intake is designed for a straightforward installation process, often requiring no cutting or modifications to the vehicle.
Installation Process
Installing the AEM Cold Air Intake on your Evo 9 can typically be done in a few hours with basic tools. Here’s a step-by-step guide to help you through the process:
- Gather Tools: You will need basic hand tools including a socket set, screwdrivers, and pliers.
- Remove the Stock Intake: Disconnect the battery, then remove the stock air intake system by loosening the clamps and removing the airbox.
- Install the AEM Intake: Follow the instructions provided with the AEM kit to install the new intake, ensuring all connections are secure.
- Reconnect Everything: Reconnect the battery and double-check all components before starting the engine.
Power Improvements and Performance Testing
After installation, many Evo 9 owners report noticeable improvements in performance. To quantify these improvements, it’s advisable to conduct performance testing. Here are some methods to measure the impact of the AEM Cold Air Intake:
- Dyno Testing: A dynamometer can provide accurate horsepower and torque figures before and after the installation.
- 0-60 Time Trials: Timing your 0-60 mph acceleration can give a practical sense of the performance boost.
- Quarter-Mile Testing: Testing your vehicle on a quarter-mile track can showcase improvements in overall speed and performance.
Additional Upgrades for Enhanced Performance
While the AEM Cold Air Intake is an excellent upgrade, combining it with other modifications can lead to even greater performance gains. Here are some additional upgrades to consider:
- High-Performance Exhaust System: Upgrading the exhaust can improve airflow and reduce back pressure.
- ECU Tuning: A proper tune can optimize the engine’s performance parameters to work in harmony with the new intake.
- Upgraded Intercooler: A larger intercooler can help maintain lower intake temperatures, further enhancing performance.
Conclusion
The AEM Cold Air Intake is a powerful upgrade for the Mitsubishi Lancer Evolution IX, providing significant improvements in horsepower, throttle response, and overall driving enjoyment. When combined with other performance enhancements, it can transform your Evo 9 into a true powerhouse on the road or track. Whether you are a seasoned enthusiast or a newcomer to the world of performance upgrades, the AEM Cold Air Intake is a worthwhile investment for any Evo 9 owner.
