The FA20 engine, known for its balance of performance and efficiency, has become a favorite among car enthusiasts. Modifications to this engine can significantly enhance its power output and overall driving experience. One of the most effective upgrades is an intake system, which can provide noticeable horsepower gains. In this article, we will explore how a $1,200 intake system can add 20 horsepower to your FA20 engine.
Understanding the FA20 Engine
The FA20 engine is a flat-four, or boxer, engine produced by Subaru. This unique design allows for a lower center of gravity, improving handling and stability. The engine is equipped with a turbocharger, which enhances its power output while maintaining fuel efficiency. To maximize the potential of the FA20 engine, modifications are often necessary.
Why Upgrade the Intake System?
The intake system plays a crucial role in engine performance. It is responsible for delivering air to the engine, which is essential for combustion. A high-performance intake system can:
- Increase airflow to the engine.
- Improve throttle response.
- Enhance engine sound.
- Contribute to better fuel efficiency.
How an Intake System Works
An aftermarket intake system typically replaces the factory air intake components. This includes the air filter, intake tubing, and sometimes the throttle body. By using larger diameter pipes and high-flow air filters, these systems reduce restrictions and allow for a greater volume of air to enter the engine.
Choosing the Right Intake System
When selecting an intake system for the FA20 engine, consider the following factors:
- Material: Look for systems made from high-quality materials like aluminum or high-density polyethylene.
- Design: A well-designed intake system should have smooth bends and minimal restrictions.
- Brand Reputation: Choose a reputable brand known for performance parts.
- Compatibility: Ensure the system is specifically designed for the FA20 engine.
Benefits of a $1,200 Intake System
Investing in a $1,200 intake system can yield significant benefits for your FA20 engine:
- Increased Horsepower: Many high-quality intake systems can add up to 20 horsepower, making your vehicle more responsive and powerful.
- Improved Torque: A better intake can also enhance torque, providing a more enjoyable driving experience.
- Enhanced Sound: A performance intake often results in a more aggressive engine sound, which many enthusiasts appreciate.
- Better Fuel Economy: With improved airflow, your engine can run more efficiently, potentially leading to better fuel economy.
Performance Gains
The performance gains from an upgraded intake system can vary based on several factors, including the specific make and model of the intake, other modifications, and the tuning of the engine. However, many users report an increase of around 20 horsepower with a quality intake system installed.
Installation Process
Installing a new intake system is typically straightforward, but it is essential to follow the manufacturer’s instructions carefully. Here are the general steps involved:
- Gather Tools: Common tools include a socket set, screwdrivers, and pliers.
- Remove the Factory Intake: Disconnect the battery and remove the factory air intake system.
- Install the New Intake: Follow the instructions to install the new intake system securely.
- Reconnect Everything: Ensure all connections are tight and reconnect the battery.
- Test Drive: Take your vehicle for a test drive to experience the performance improvements.
Tuning Your FA20 Engine
After installing a new intake system, tuning your FA20 engine can further enhance performance. Tuning adjusts the engine’s air-fuel mixture and ignition timing, optimizing it for the new airflow characteristics. Many enthusiasts opt for a custom tune to maximize the benefits of their upgrades.
Types of Tuning
- ECU Reflash: This involves reprogramming the engine’s computer to accommodate the new intake.
- Piggyback Systems: These systems work alongside the factory ECU to enhance performance without complete replacement.
- Standalone ECUs: For those looking for maximum control, standalone ECUs allow for extensive tuning options.
Conclusion
Upgrading the intake system of your FA20 engine is a smart investment for those looking to enhance performance. A quality $1,200 intake system can add up to 20 horsepower, improve throttle response, and contribute to a more enjoyable driving experience. Coupled with proper tuning, these modifications can unlock the full potential of your engine, making your vehicle more powerful and efficient.
