At its core, a cold air intake system is designed to increase the amount of cool air that flows into an engine. This, in turn, can lead to improved engine performance and better fuel economy. In this article, we will explore the benefits of installing a cold air intake system, as well as the different types of cold air intake kit available on the market.

What Is a Cold Air Intake?

A cold air intake is a system that replaces the factory air box and intake tube with an aftermarket unit. The purpose of this is to allow for cooler, denser air to enter the engine, which can lead to improved combustion and more power.

Benefits of a Cold Air Intake

There are several benefits to installing a cold air intake system in your vehicle. Here are just a few:

Improved Engine Performance: By increasing the amount of cool, dense air that enters the engine, a cold air intake system can improve combustion and increase horsepower and torque.

Better Fuel Economy: When the engine is running more efficiently, it uses less fuel. A cold air intake system can help your vehicle achieve better fuel economy.

Enhanced Sound: Many cold air intake systems have a more aggressive sound than stock systems, which can make your vehicle sound more powerful.

Types of Cold Air Intakes

There are two main types of cold air intakes: open and closed.

Open Cold Air Intakes: These systems use an exposed filter element and typically offer the highest levels of airflow. However, because they are open to the engine bay, they can also draw in hot air, which can negate some of the performance gains.

Closed Cold Air Intakes: These systems use an enclosed air box to keep the air filter isolated from the rest of the engine bay. While they may not offer quite as much airflow as open systems, they are less susceptible to heat soak and can provide more consistent performance gains.

Choosing the Right Cold Air Intake

When choosing a cold air intake system, there are several factors to consider. These include:

Compatibility: Make sure the system you choose is compatible with your vehicle’s make and model.

Filter Material: Look for a system with a high-quality filter that will effectively trap contaminants without restricting airflow.

Build Quality: Choose a system that is well-built and made from high-quality materials.

Performance Goals: Consider your performance goals when selecting a system. Do you want maximum horsepower gains, or are you more concerned with fuel economy?


A cold air intake system can be an excellent upgrade for those looking to improve engine performance and fuel economy. With so many different types of cold air intakes on the market, it’s important to do your research and choose a system that meets your specific needs and performance goals. Whether you opt for an open or closed system, a high-quality cold air intake can help take your vehicle’s performance to the next level.
