How to Install a Performance Short Ram Intake in a Mitsubishi Lancer Evolution for Better Airflow?

April 5, 2024

Have you ever pondered the idea of boosting your Mitsubishi Lancer Evolution’s performance by enhancing its air intake system? Or perhaps you’re simply a car enthusiast who wants to understand the nitty-gritty details of a performance short ram intake. Either way, you’ve come to the right place. This article will walk you through the entire installation process and explain how it can enhance your car’s power and performance.

Understanding the Role of an Air Intake System in Your Car

It’s essential to grasp the concept of an air intake system before diving into the installation process. The air intake system in your car is responsible for supplying your engine with the air it needs to operate. The more air supplied, the more power the engine can produce.

Several after-market products like the Injen, AEM, K&N, and HPS short ram intake systems aim at increasing the amount of air supplied to the engine. Unlike the standard air intake system that draws air from the front of the car, a short ram intake system is designed to draw air directly from the engine bay, exposing it to more heat from the engine but also allowing for a faster air delivery.

Picking the Right Short Ram Intake System

Choosing the right short ram intake system can be a daunting task given the wide array of products available in the market. However, brands like Injen, AEM, K&N, and HPS are renowned for their reliable and high-performance products.

For a Mitsubishi Lancer Evolution, an HPS short ram intake is a perfect fit given its design characteristics that make it compatible with this car model. The HPS intake system also comes with a heat shield, which minimizes the heat from the engine that the intake system is exposed to, improving the quality of air delivered to the engine.

Installing the Short Ram Intake System

When it comes to installing the short ram intake, the process is rather straightforward. You will need some basic tools, including a screwdriver, socket wrench, and pliers. Also, ensure you have your HPS cold ram intake system and a new air filter ready.

First, you will need to remove the existing air intake system. Use your socket wrench and pliers to disconnect the system and pull it out. Once that’s done, you can install your new HPS short ram intake system in its place. Fit the intake tube and use your screwdriver to tighten it into position.

Next, install the air filter onto the intake tube’s end. Ensure that it’s secure to prevent any loose particles from entering the intake system. Finally, install the heat shield around the short ram intake system. This will prevent the system from drawing in hot air from the engine, thus maintaining the quality of intake air.

Post-Installation Performance Check

After successfully installing your new short ram intake system, you must assess its performance. Start up your car and let it idle for a few minutes. Listen for any unusual noises and observe if there are any changes in the engine’s performance. If everything appears normal, take your Lancer Evolution for a short drive to get a feel of its improved performance.

You should notice a significant increase in power, especially during acceleration. The engine will also respond more quickly due to the improved air supply. However, if you notice any anomalies in the car’s behavior, it would be wise to revisit your installation and ensure everything was done correctly.

Maintaining Your Short Ram Intake System

Just like any other part of your car, your short ram intake system also requires regular maintenance. The air filter, in particular, needs to be cleaned or replaced regularly to ensure optimal performance. A dirty or clogged filter will hinder airflow and compromise the system’s performance.

Regularly inspect the intake tube and heat shield for any signs of wear and tear. This is especially important if your car is often exposed to harsh driving conditions. Keep in mind that the better you take care of your short ram intake system, the longer it will serve you and your car.

As you can see, installing a short ram intake system in your Mitsubishi Lancer Evolution, is not as complicated as it may seem. With a little bit of patience and the right tools, you can enhance your car’s performance and enjoy a more responsive and powerful ride. Happy motoring!

Long-Term Benefits of Installing a Short Ram Intake System

Installing a short ram intake system in your Mitsubishi Lancer Evolution not only enhances its immediate performance but also brings about several long-term benefits. Unlike the standard air intake system that primarily relies on cold air, the short ram intake system takes advantage of the hot air prevalent in the engine bay, thereby delivering a constant and reliable airflow.

Notably, the use of a short ram intake system can lead to a considerable increase in your car’s horsepower and torque. This is because the short ram intake system allows air to flow into the engine at a much faster rate compared to the factory-installed intake system. Consequently, the engine’s combustion process is significantly enhanced, resulting in an increase in horsepower.

However, it’s critical to remember that while short ram intake systems may increase horsepower, the gains might not be as significant as those achieved with cold air intake systems. Nevertheless, they are much easier to install and don’t require as much maintenance.

In addition to horsepower gains, the use of a short ram intake can also lead to better gas mileage. By ensuring a more efficient airflow, the engine doesn’t have to work as hard, thus reducing fuel consumption.

Your Lancer Evolution is also likely to have a longer lifespan with a short ram intake system. The air filter that is part of the system prevents harmful debris and contaminants from entering your engine, thus reducing wear and tear. Consequently, regular maintenance of the intake system, particularly the air filter, ensures that your car remains in good condition for a long time.


In conclusion, installing a short ram intake system is a great way to enhance the performance of your Mitsubishi Lancer Evolution. The increase in horsepower, improved fuel efficiency, and extended lifespan of the vehicle are all compelling reasons to consider this upgrade.

Choosing a reputable brand, such as HPS Performance, and regular maintenance of your air filter and heat shield, will ensure you experience these benefits for a long time. While the installation process may seem daunting, with the right tools and patience, it can be a rewarding project.

Don’t be afraid to dive in and give your Lancer Evolution the boost it deserves. Remember, the journey of increasing your vehicle’s performance is as exciting as the destination. The satisfaction of seeing your car respond more quickly and deliver more power is well worth the effort. With your newly installed short ram intake system, you’re set for an exhilarating ride. So, buckle up and enjoy the journey!
