Why a Ram Air Intake Will Improve Your Subaru Impreza WRX
The Subaru Impreza WRX is a popular car among car enthusiasts for its performance and handling. The WRX is equipped with a turbocharged engine that gives it a boost in power. However, the stock air intake system is restrictive, which can limit the performance of the engine. Luckily, there is a solution to this problem: the ram air intake. A ram air intake can enhance the performance of your Subaru Impreza WRX by improving the throttle response and increasing power output. In this article, we will discuss what a ram air intake is and how it works, as well as the top ram air intakes for your WRX.
What is a Ram Air Intake and How Does It Work?
A ram air intake is an air intake system that is designed to increase the amount of air that enters the engine by using the force of the moving vehicle to force air into the engine. The ram air intake system works by capturing the air that is flowing into the engine compartment while the car is moving forward and directing it into the air intake system. This increases the volume of air that enters the engine, which results in a higher air-to-fuel ratio and increased power output.
One of the advantages of a ram air intake is that it can provide a significant improvement in throttle response. This means that the engine will respond more quickly to changes in the throttle position, which can improve the overall driving experience. Additionally, a ram air intake can also improve fuel economy by increasing the efficiency of the engine.
Comparison of Top Ram Air Intakes for Subaru Impreza WRX
There are several ram air intakes available on the market for the Subaru Impreza WRX. The most popular ones are the COBB Tuning SF Intake System, the AEM Cold Air Intake System, and the Perrin Performance Cold Air Intake System.
The COBB Tuning SF Intake System is known for its high-quality construction and excellent performance. It features a custom airbox that keeps hot engine bay air out, and a reusable high-flow air filter that can be cleaned and reused multiple times. This intake system is designed to work with the factory tune and does not require any additional tuning.
The AEM Cold Air Intake System is another popular choice among WRX owners. It features a mandrel-bent aluminum intake tube that is designed to provide a smooth, unrestricted flow of air to the engine. The intake system also includes a washable and reusable air filter, and a heat shield that keeps hot air from entering the intake.
The Perrin Performance Cold Air Intake System is another high-quality choice for the Subaru Impreza WRX. It features a 3-inch aluminum intake tube that is designed to provide maximum airflow to the engine. The intake system also includes a heat shield that keeps hot air from entering the intake, and a washable and reusable air filter.
Installation Guide: How to Install a Ram Air Intake on Your Subaru Impreza WRX
Installing a ram air intake on your Subaru Impreza WRX is a relatively straightforward process that can be completed in a few hours with basic hand tools. The first step is to remove the factory air intake system and install the ram air intake. This can involve removing the bumper and other components, depending on the specific intake system.
Once the ram air intake is installed, it is important to ensure that all connections are tight and secure. It is also recommended to check the air filter regularly and clean or replace it as needed to ensure optimal performance.
Performance Test Results: Before and After Installing a Ram Air Intake
The performance improvements that can be achieved with a ram air intake on a Subaru Impreza WRX can be significant. Many WRX owners have reported improvements in throttle response, power output, and overall driving experience after installing a ram air intake.
In a dyno test performed by COBB Tuning, a Subaru Impreza WRX with the COBB Tuning SF Intake System installed showed an increase of 14 peak horsepower and 16 lb-ft of torque compared to the stock air intake system. This translates to improved acceleration and overall performance.
Conclusion: The Best Ram Air Intake for Subaru Impreza WRX
In conclusion, a ram air intake can provide significant performance improvements for your Subaru Impreza WRX. The COBB Tuning SF Intake System, AEM Cold Air Intake System, and Perrin Performance Cold Air Intake System are all popular choices that offer high-quality construction and performance improvements. The installation process is relatively straightforward and can be completed with basic hand tools. With a ram air intake installed, you can expect improved throttle response, increased power output, and a better overall driving experience.
