The FA20 engine, found in various Subaru and Toyota models, has gained popularity among car enthusiasts for its performance potential. One of the most effective modifications to enhance its performance is the installation of a cold air intake system. This article will explore the best cold air intake systems for the FA20 engine, discussing power gains, costs, and installation tips.
Understanding Cold Air Intakes
A cold air intake (CAI) system is designed to draw cooler air into the engine, which is denser and contains more oxygen. This increase in oxygen can lead to better combustion and, consequently, more power. The FA20 engine can particularly benefit from a CAI due to its turbocharged design.
Benefits of Cold Air Intake Systems
- Increased Horsepower: Cold air intakes can provide noticeable horsepower gains, often ranging from 5 to 20 horsepower, depending on the system.
- Improved Throttle Response: A CAI can enhance throttle response, making the vehicle feel more responsive during acceleration.
- Better Engine Sound: Many enthusiasts appreciate the deeper, more aggressive sound that a cold air intake can provide.
- Potential Fuel Efficiency Gains: By improving the air-to-fuel ratio, some users report better fuel economy.
