Does A Cold Air Intake Make Your Car Louder? (Detailed Answer : 2022)

The cold air intake has a lot of benefits to the engine of a car, but we will focus on is the improved sound.

The question, “Does a cold air intake make your car louder?”

Arises when someone wants to install a cold air intake on his vehicle.

The cole air intake is responsible for directing oxygen to the combustion chamber, which helps the engine burn fuel more efficiently.

The modification improves the vehicle’s horsepower, performance, and sound.

In this article, we will answer the question about cold air intake and other related questions.

Does A Cold Air Intake Make Your Car Louder?

Cold air intake is a popular way to improve the power capacity of your engine.

But people are not only interested in the power gain but also constantly ask if it can make cars louder.

The answer to the question is yes, cold Air intake will make your car louder and sound more aggressive.

The increase in the car’s sound is because the cool air intake changes the airflow in the engine.

You can hear the sound of air rushing through the engine.

The rushing air then results in an aggressive sound that is pretty impressive to hear.

It is one of the reasons cold air intake is a popular modification.

How Does A Cold Air Intake Work?

Before you can understand how a cold air intake makes a car’s engine louder, you must understand how the modification works.

First of all, you must understand what an air intake is.

The air intake has the sole purpose of providing the engine with oxygen.

The air is an important factor that aids fuel burning in the engine combustion system.

There are different types of air intake, and they are positioned differently.

The cold air intake is a type of air intake that serves as an engine modification.

It helps give your engine more air to work more efficiently and produce more power.

The cold air intake diverts more cold air into the engine’s combustion system.

As we know, the engine does not just work using only fuel.

It uses air and fuel to produce power used to power the car to move.

The more efficiently air is mixed with fuel, the more power the vehicle uses.

A colder air provides better combustion when mixed with fuel, and this is because colder air contains more oxygen density.

The cold air intake can capture cold air because the air filter is moved outside the engine.

With the position of this air intake, it can suck cold air into the engine combustion system with ease.

The engine can achieve more combustion once the captured air is mixed with fuel in the combustion system.

The cold air intake can easily be seen when you open the car hood.

It is strategically located where it can easily get cold air for the engine to use.

You can see the intake tube either at the fender, hood scoop, or grille.

How Does Cold Air Intake Make the Engine Loud?

Now that you understand how the cold air intake works, we can dive into how it affects the car’s sound.

The loud and aggressive sound coming from the engine due to the cold air intake is called the intake sound.

The intake sound is caused by two main categories, which are cold air intake noise and the other component parts.

Due to cold air intake into the engine, the first category is an easy component to understand.

As we have explained previously, the cold air intake is responsible for sucking or capturing cold air and then transferring this cold air into the combustion system.

The process of sucking this air and transferring it to the engine combustion system could increase the sounds coming from the engine system.

The rush of air can cause a lot of noise, especially when the air is sucked with so much intensity.

Also, the air crashing on components of the engine and cold air while being sucked in can cause noise.

We should also understand that the type of engine could also influence the sound of the intake of air process.

You can not expect the same sound and performance from a supercharged engine as a normal engine.

You can expect a louder and more aggressive sound with a supercharged engine.

We will get more into this as we go on.

The second aspect is the other components, including other parts of the engine that contribute to its increased sound.

Some of which include valves, fuel injectors and other parts of the engine.

With the increase in the cold air entering the engine, you can expect an increase in the performance of other parts of the engine.

As the saying goes, with more power comes more responsibility.

You can expect the sound coming from these components to change because of the increase in power caused by the cold air intake.

Apart from the factors mentioned above, other factors can influence the engine’s sound caused by the installation of a cold air intake.

Some of these factors include the following.

01. Exhaust System

The exhaust system plays a major role in the sound of a vehicle whether or not there is a cold air intake installed.

The exhaust is a major tool that influences the airflow in the car.

So, the type of exhaust or the exhaust upgrade you have done on your car may influence the car’s sound.

Having an upgrade on the exhaust system like installing a complete aftermarket exhaust, muffler delete, and many more can completely change the sound of your engine.

So, if you are looking to further upgrade the sound of your engine after the cold air intake installation, you can consider getting an exhaust upgrade.

You must understand that the cold air intake does not influence the sound of the exhaust.

The cold air intake strictly affects the performance and sound of the engine.

The exhaust system only acts as an added sound improvement.

02. Charged Engine

A major influence of sound after installing a cold air intake is charged engine.

The sound that you get from a cold air intake may be different with a charged engine.

Also, the engine’s sound depends on the type of charger you are installing or have already installed in the engine.

With a charged engine like the turbocharger, you may not experience any difference in the sound immediately.

You will only experience a difference when you speed up driving or rev up.

It is because turbocharged engines make use of forces induction.

This means that the turbocharger will not react to the engine unless enough pressure is built up.

Unlike the turbocharger, the supercharger is quite different.

The supercharger is instantly responsive to the engine because the engine itself powers the supercharger.

Once the charged engine is switched on, you will notice a difference in the sound.

Other engine upgrades and chargers will give a different result in sound when used with cold air intake.

It all depends on the result you are you want.

03. Type of Cold Air Intake

There are different types of cold air intakes built to suit specific models of cars.

What makes a cold air intake different depends on several things.

Cold air intakes come in different sizes and designs.

Many deliver an additional quantity of cold air into the engine.

These specific features can influence the sound that the engine delivers.

You can expect more sound improvement from a cold air intake that delivers more cold air into the engine.

The amount of air rushing into the engine is more, and the sound difference can be heard.

Other factors like the size of the cold air intake could also affect the engine’s sound.

Also, note that not all the special features of the cold air intake could influence the engine’s sound.

04. Engine Type

The engine type and its components can also influence the engine’s sound after the intake has been installed.

Components like the number of valves that the engine has can also be an influencing factor.

If you do not know what an engine valve is, it can be found in the engine combustion system.

This component serves as a restriction of air and liquid entering the combustion system.

The valve opens and closes, and the cold air intake can influence this movement.

As a result of this, the sound coming from the valve could increase.

05. Diameter of the Intake

The diameter of the cold air intake is a major influence on the sound that the intake will give your car.

The diameter makes the cold air intake different from the normal air intake that comes with your engine.

An air intake with a larger intake diameter will be able to let out a more aggressive sound easily.

The large diameter of the intake allows sound to travel freely.

Why Are Cold Air Intakes illegal?

It is important to consider the legality when getting a modification if you do not want to get into trouble with the authorities.

When it comes to the cold air intake, it is not legal in every State in the USA.

Currently, there are states in the US that strictly prohibit the use of cold air intake.

The states where the cold air intake is considered illegal include Arizona, New York, Pennsylvania, California and other states where the necessary permission to use one has not been granted.

The major reason for the illegal status of cold air intake in many states in the US is because of emissions.

The cold air intake causes changes in the air intake system, leading to changes in the car’s emissions.

California is the State that spare headed laws controlling the use of cold air intakes on the road.

They did this by creating California Air Resources Board (CARB).

CARB is a committee responsible for checking and preventing the State from air pollution.

They have established programs to ensure that the State is free from air pollution.

One of these programs is establishing a regulation that guides the use of cold air intake.

The regulation states that any cold air intake without a CARB-approved Executive Order number will not pass an emission test.

With this law, you can only use a cold air intake with a CARB-approved EO number when driving on the road of California.

If you do not have an approved cold air intake, it is considered illegal, and you can get in trouble with the authority.

With the establishment of this law in California, other states in the US have decided to adopt this system.

States like Pennsylvania have adopted the CARB EO number.

It is important that you check the laws in your state before you decide to install a cold air intake.
