What Does a Cold Air Intake Do?

Vehicles are already fitted with standard intake systems, but these models are often of poor quality and become quickly clogged with debris. Using a factory-installed air intake system is similar to driving your vehicle while it’s suffering from a cold – it's breathing, but has a restricted performance. To enhance vehicle performance, a cold air intake system does the following things:

Provides Uninterrupted Airflow

Intake systems move the air filter to the outside of the engine compartment, resulting in cooler air being sucked into the vehicle’s engine for combustion. The cooler air further consists of more oxygen that increases the power produced by the engine. Since the filter is located near the upper wheel well, it ensures unrestricted airflow to the engine.

Increases Acceleration and Enhances Engine Performance

The right cold air intake system is capable of improving horsepower, adding anywhere from an extra five to twenty horsepower. The engine’s responsiveness is further improved because of the increased amount of cooler air available for combustion.

Improves Fuel Economy

The increase in oxygen also improves fuel economy. A combination of fuel and oxygen power your vehicle, so the more oxygen available for combustion, the less fuel will be needed. This results in a more fuel-efficient vehicle, significantly reducing your vehicle’s running costs.

Enhances Engine Sound

As cold air is sucked into the engine, it creates a more aggressive and satisfying sound. While this sound is preferred by many car enthusiasts, you can also choose intake systems that muffle this sound if you don’t like it.

What Are the Components of a Cold Air Intake?

To better understand cold air intakes, it’s essential that you know the numerous parts it’s constructed of. Some of these components include:

Air Filter

This is arguably the most important part of every intake system, whether warm or cold air. The air filter protects the combustion chamber from dirt, dust, and other particles, preventing dull engine power, reduced fuel efficiency, and any severe damage that might be caused over time. Most models are equipped with their own specialized filters.


The tubing in cold air intake systems suck in cold air and deliver it to the engine. It's usually designed with some of the best materials, including plastic, stainless steel, rubber, and aluminum, and usually runs through the grille of the vehicle.

Mass Flow Sensor

As the name suggests, a mass flow sensor determines the total air mass flowing through the intake system and into the engine. The sensor calculates the air mass and then calibrates the amount of air flowing into the engine to maximize performance. There are two types of mass flow sensors – hot wire and vane meter.

How Do I Choose a Cold Air Intake For a 6.0 Powerstroke?

With so many cold air intake systems available today, choosing the best one can be an extremely technical and daunting task. While these units are relatively inexpensive, there are still some things you should look out for. Some of these features include:

Heat Shield

Quality models are usually designed with a heat shield. This further insulates the intake system from the heat produced by the engine, giving you a bit more boost.

Fender Mount

Some models are innovatively designed and can be mounted to the fender, allowing cooler air into the engine. In short, intakes with a fender mount enable users to fully take advantage of cold air combustion.

Water Ingestion

If water gets inside the intake system, it can negatively affect performance and significantly damage the system. Hence, make sure you choose a model that’s designed with a bypass valve to avoid water from being ingested in the system, especially if you live in areas with regular rainfall.

Some models are also designed with a two-piece system that enables users to convert the system into a short ram intake. Once the lower portion is removed, water will not enter the system at all.

What Do I Need To Know Before Buying?

Like every other bolt-on modification, the most important thing to consider is the correct application. Before you purchase a cold air intake for your vehicle, make sure you consider the following factors:

Vehicle-Specific Design

Most cold air intakes are designed to be compatible with a specific vehicle and engine type, make, model, and year. Make sure the model you’ve chosen can be used with your specific vehicle.


As mentioned above, cold air intakes reduce accumulated heat, allowing colder and denser air to flow into the engine. Thus, it’s better to choose a system that’s designed with heat-resistant materials.

Style of the Cold Air Intake System

There are two types of cold air intake systems – true cold air intakes and the short ram systems. Short ram systems make it easier to access the air filter and require less fabrication or "plumbing" work.

On the other hand, true cold air intakes move the air filter forward as much as possible, resulting in more cold air flowing into the engine compared to short ram systems.

Intake Tube Flow

Make sure you check the flow of the tubing before you make your purchase. If the model has straight hoses, it will result in a more efficient airflow than one with significantly curved ones.


Cold air intake systems are essential for a vehicle’s engine health. They not only enhance the performance but also improve the longevity and efficiency of the vehicle. However, choosing the right model can be an extremely difficult task. Hopefully, the aforementioned guide cleared any confusion you had and helped you find the right cold air intake system.
