The Mitsubishi Lancer Evolution IX, commonly known as the Evo 9, is a performance-oriented vehicle that has captivated car enthusiasts since its release. One of the most popular modifications among Evo 9 owners is the installation of a cold air intake, specifically the APS (Advanced Performance Systems) Cold Air Intake. This article explores the performance gains you can expect from installing an APS cold air intake on your Evo 9.
Understanding Cold Air Intakes
A cold air intake system is designed to replace the factory air intake system with a more efficient design that allows for cooler, denser air to enter the engine. Cooler air contains more oxygen, which can lead to improved combustion and, consequently, more power. The APS cold air intake is engineered specifically for the Evo 9, providing optimal fitment and performance benefits.
Benefits of the APS Cold Air Intake
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
- Better fuel efficiency
Increased Horsepower and Torque
One of the most significant advantages of installing an APS cold air intake is the potential increase in horsepower and torque. While the exact gains can vary based on other modifications and tuning, many Evo 9 owners report an increase of anywhere from 10 to 20 horsepower after installation. This increase is primarily due to the improved airflow and cooler air entering the engine.
Improved Throttle Response
The APS cold air intake not only increases power but also enhances throttle response. Drivers often notice a more immediate reaction when pressing the accelerator, making the car feel more agile and responsive. This improvement can significantly enhance the driving experience, especially during spirited driving or track days.
Enhanced Engine Sound
Another appealing aspect of the APS cold air intake is the distinct sound it produces. Many enthusiasts appreciate the deeper, more aggressive intake noise that accompanies the installation of a cold air intake. This auditory feedback can enhance the overall enjoyment of driving the Evo 9.
Better Fuel Efficiency
While performance gains are often the primary focus, an APS cold air intake can also contribute to improved fuel efficiency. By allowing the engine to breathe more freely and operate more efficiently, drivers may experience better fuel economy under certain driving conditions. However, this improvement can vary based on driving habits and other modifications.
Installation Process
Installing an APS cold air intake on your Evo 9 can be a straightforward process for those with basic mechanical skills. Here is a general overview of the installation steps:
- Gather necessary tools: socket set, screwdrivers, and pliers.
- Remove the factory air intake system, including the airbox and intake tubing.
- Install the APS cold air intake, ensuring all connections are secure.
- Reconnect any sensors or hoses that were detached during removal.
- Test the vehicle to ensure proper operation.
Tuning Considerations
While the APS cold air intake can provide noticeable performance gains, it is essential to consider tuning your Evo 9 to maximize these benefits. A proper tune can help the engine take full advantage of the increased airflow and optimize fuel maps for better performance and efficiency.
Types of Tuning Options
- ECU Reflash: A software update to modify fuel and timing maps.
- Standalone Engine Management: A more advanced option for fine-tuning performance.
- Dyno Tuning: Professional tuning on a dynamometer to achieve optimal results.
Real-World Performance Gains
To understand the real-world performance gains from an APS cold air intake, it’s beneficial to look at user experiences and dyno results. Many Evo 9 owners have reported their results after installation, showcasing the effectiveness of this upgrade.
- Owner A: 15 horsepower gain, improved throttle response.
- Owner B: 12 horsepower gain, enhanced engine sound.
- Owner C: 20 horsepower gain, better fuel efficiency on highway driving.
Conclusion
In summary, the APS cold air intake is a popular modification for the Evo 9 that can provide significant performance benefits. With potential gains of 10 to 20 horsepower, improved throttle response, and enhanced engine sound, it’s an attractive option for enthusiasts looking to boost their vehicle’s performance. Pairing this upgrade with proper tuning can further maximize the benefits, ensuring that your Evo 9 performs at its best.
