Does Cold Air Intake Make A Car Louder?

Are you a car enthusiast who wants to know if cold air intake affects the sound of a car? You are at the right place because I'll explain everything you need to know about the cold air intake in this article. 

About the question that does cold air intake makes a car louder? The smaller answer is. Yes, it does. It makes the sound of your car more aggressive. You will be able to hear air flowing into the air intake when you release the throttle. The sound generated at this point will feel very bold and remarkable.

What's the Role of Air in a Car? 

What's the role of air in the engine? A car needs the power to run, and power is produced when a mixture of fuel and air is ignited in the combustion chamber. The air present in the engine is used during the combustion process, so to continue this process, a constant supply of air is required. More oxygen means more considerable combustion and more power for the car. Let's now move to the cold air intake.

How Does Cold Air Intake Work?

We know that cold air is denser and heavier, containing more oxygen from our high school science. The cold air remains at the bottom while the hot air is lighter and moves at the top side. That's why an AC placed at the top side of the room will cool the hot air.

The custom cold air intake is placed in the engine hub besides other hot components. It absorbs the hot air (which is low on oxygen) available in the engine hub, which is not good.

What cold air intake does is it re-routes the air intake route. Instead of the air in the engine hub, it sucks cold air near the wheels. This cold air is rich in oxygen, so the scope of combustion will increase.

Sound Changes by Cold Air Intake

In addition, the performance cold air intake will also make the sound louder and more aggressive. You will also hear the sound of air flowing into the engine. But how does this change occur? Let's have a look at the reasons.

More Air Flow

The cold air intake increases the amount of oxygen sucked into the engine. Whether the air is cold or hot, more air will have more oxygen, improving the sound.

Bigger Exposed Area

If you pop the hood and try to look for the stock air intake, you probably won't find it because it is enclosed to reduce the sound produced by input. In contrast, the cold air intake exposure area is more prominent and absorbs more air. This exposure increases the sound as a side effect.


The manufacturers have to follow many regulations regarding noise pollution. After-market cold air intakes are designed to increase the vehicle's performance, and nothing else matters. So the manufacturers can do everything they want, and as a side effect, we get an excellent and aggressive sound.
