Does A Cold Air Intake Increase MPG? Tip For Beginners

For a car to operate stably, the engine system will integrate many supporting devices. One of them is the cold airflow. Currently, many people are skeptical about the use of this device. They argue that a car engine is not necessary to use a device that provides a constant flow of cool air. 

So, does a cold air intake increase MPG?

For them, a thermostat or standard radiator-like 2 row vs 3 row radiator for the engine is enough. However, this thinking is entirely wrong. The following article will help you realize the importance of cold airflow to the performance of the engine system.

What Is MPG?

MPG is a unit to measure the fuel consumption of any car engine. It is the number of miles driven per gallon. Currently, MPG is the standard unit for all car manufacturers. The manufacturer will rely on this parameter to adjust other details to minimize fuel consumption.

Does A Cold Air Intake Increase MPG?

Does A Cold Air Intake Increase MPG

The answer is yes. The amount of cold air can help increase the effective MPG index. When the airflow is drawn into the engine, it helps the system to operate in a stable condition. 

Overheating will not happen to your vehicle. Also, the check engine light will not appear intermittent flashing due to engine temperature problem.

The cold airflow will act as a new exhaust in operating principles. The air intake will help improve your vehicle’s MPG efficiency as it will allow more airflow to your engine. 

However, the increase in MPG will depend on your car. The same level of cold air but with different car models will be different. Up to a certain threshold, your car will not be able to increase the MPG index.

Using cold air for the engine system is correct in the long run. Because it increases the car’s performance, it also helps protect the engine from thermal problems. Thanks to that, your vehicle will continuously operate in the best condition.

Does Cold Air Reduce MPG?

The answer is yes. When the air intake is to improve the engine’s performance, the amount of cold air reduces the MPG. 

For example, when your car’s system lets water in, it can cause serious problems. At this time, cold air will help them overcome that situation. Although it reduces the car’s MPG, it will help keep your car safe.

How To Choose The Right One?

Choosing the right refrigerant intake system will help improve your engine’s performance. 

More cold air will be in the engine with a quality system. As a result, it will help ensure the car’s fuel is more efficient and evenly. At that time, the car running hot but not overheating will not happen to your vehicle.

In addition, if you want a cold air intake with long service life and can save fuel, you will need to determine if the air intake pipes are behind the grille. This determination will improve and ensure the air’s performance intake. The car engine can access the best airflow.

However, if the intake system draws hot air from the vehicle’s engine compartment, you should replace it with a cold intake system. It will help the process of regulating the engine temperature better. Besides using the air intake system, the thermostat is also an indispensable tool for every car. It will work with the air intake system to help regulate the engine temperature at a stable level.

Frequently Asked Questions(FAQ’s)

1.Do cold air intakes shorten engine life?

The answer is no. This type of air inlet will help your engine work well in all conditions. At the same time, all the surrounding details will also work well if you have a good filter. Therefore, before you intend to use the air intake, you should check the compatibility between the components in the same engine system.

2.How much horsepower does a cold air intake add?

When you introduce cold air into the engine system, your vehicle can more evenly mix the fuel with that air. 

At the same time, it will help to generate more capacity. In addition, when the amount of air passing through the intake manifold and filter is stabilized, the horsepower can be increased from 10-15 horsepower. 

Therefore, drivers should improve the cold air intake so that the maximum air passes through the intake manifold and filter.

3.Does the K&N filter increase performance?

The answer is yes. The K&N filter is to help improve the speed of torque and horsepower. At that time, more cold air will be in the engine system. This improvement will help your car burn more robust and stable fuel faster. These oil-based cotton filters can deliver up to 50% more air.

4.Do you need a tune after cold air intake?

You do not need to adjust your vehicle after installing the cold air intake. Because the adjustment will be costly for you, at the same time, it only helps to optimize the amount of cold air and will not have any other benefits. 

Therefore, you can upgrade and install it easily without any further adjustments with a cold air inlet.


Hopefully, this article will help you better understand the cold air intake for the car’s engine system. This part will significantly improve your car’s MPG index. The driver can travel longer distances and still save maximum fuel use at that time. 

However, the MPG improvement will need to depend on the vehicle you are using. With each car, it will have a specific limit. Therefore, once it has reached its maximum efficiency, the cold inlet will not improve the number of miles per gallon.
