The Scion FR-S is known for its lightweight design and agile handling, making it a favorite among car enthusiasts. However, many owners seek to enhance their vehicle’s performance further. One popular modification is upgrading to a K&N cold air intake system, which promises to boost power and throttle response. This article explores the real-world results of this upgrade.
Understanding Cold Air Intakes
A cold air intake system replaces the factory air intake system, allowing for a greater volume of cooler air to enter the engine. Cooler air is denser and contains more oxygen, which can lead to improved combustion and increased power output. K&N is a well-known brand in the automotive industry, recognized for its high-performance air filters and intake systems.
Benefits of Upgrading to a K&N Cold Air Intake
- Increased Horsepower: One of the most significant benefits of installing a K&N cold air intake is the potential for increased horsepower. Many users report gains of 10-15 horsepower on average.
- Improved Throttle Response: With better airflow, drivers often experience a more responsive throttle, making the car feel more lively and engaging.
- Enhanced Engine Sound: The K&N intake can provide a deeper, more aggressive engine sound, enhancing the driving experience.
- Reusable Filter: K&N filters are washable and reusable, reducing long-term maintenance costs compared to disposable filters.
Installation Process
Installing a K&N cold air intake on a Scion FR-S is generally straightforward and can be completed with basic tools. Here’s a brief overview of the installation process:
- Gather Tools: You’ll need a socket set, screwdrivers, and pliers.
- Remove the Stock Intake: Disconnect the battery, then remove the factory intake system, including the airbox and intake tubing.
- Install the K&N Intake: Follow the instructions provided with the K&N kit to install the new intake system, ensuring all connections are secure.
- Reconnect the Battery: After installation, reconnect the battery and start the engine to check for any issues.
Real-World Performance Results
Many Scion FR-S owners who have upgraded to a K&N cold air intake report noticeable improvements in performance. Here are some real-world results based on user experiences and dyno tests:
- Dyno Tests: Various dyno tests have shown power gains of up to 15 horsepower at the wheels, depending on other modifications and tuning.
- Throttle Response: Drivers report a more immediate throttle response, particularly in the mid-range RPMs where the FR-S tends to feel more sluggish.
- Fuel Efficiency: Some users have noted slight improvements in fuel efficiency, particularly during highway driving, due to better airflow.
Considerations Before Upgrading
While upgrading to a K&N cold air intake offers many benefits, there are a few considerations to keep in mind:
- Warranty Implications: Modifications may affect your vehicle’s warranty. Check with your dealer before proceeding.
- Tuning Needs: For optimal performance, consider tuning your engine after installation, especially if you have other performance modifications.
- Maintenance: While K&N filters are reusable, they require regular cleaning to maintain performance.
Conclusion
Upgrading to a K&N cold air intake can significantly enhance the performance of your Scion FR-S, providing increased horsepower and improved throttle response. While the installation process is straightforward, it’s essential to consider warranty implications and maintenance requirements. Overall, many owners find that the benefits far outweigh any potential drawbacks, making it a worthwhile upgrade for those looking to maximize their driving experience.
