Whenever you are installing or considering buying a cold air intake for your vehicle, you may be wondering: does a cold air intake make your car louder? When you install an air intake system, you naturally want to improve the performance and sound of your car.
Yes, it’s true that a cold air intake will make any car louder than before. Because when you fit a cold air intake, the larger diameter and free-flowing design of the intake manifold allow more air into the engine.
This increased airflow can create a louder engine noise, especially when accelerating. But it also depends on the type of cold air intake and the vehicle in which this retrofit product is installed.
In this article, we will address the controversy and explore the science behind how a cold air intake works, as well as the impact it can have on your car’s engine sound.
We will also see how the noise level of your car increases. Whether you’re a gear connoisseur or just curious about car mods, read on to find the answer once and for all.
Know About How Does A Cold Air Intake Work
A cold air intake is an aftermarket air intake system used to lower the temperature of the air entering the engine. This is usually done by relocating the air filter out of the engine compartment or by using a larger, open-air box.
Colder air is denser than warm air and therefore contains more oxygen molecules. The components of a cold air intake system typically include an air filter, heat shield, and a specially designed intake manifold.
They all work together to maximize the amount of cold air drawn into the engine. However, cold air intakes have some disadvantages. One is that they can sometimes cause engine oil to foam, which can lead to reduced lubrication and increased wear.
Why Do You Require Air In An Engine?
Air is essential for the proper functioning of an engine. An engine needs air to mix with fuel to create the combustion needed to generate electricity. The process by which an engine draws in the air is called the intake stroke.

During this stroke, the intake valve opens and the piston moves down, creating a vacuum that allows air to flow into the engine. The air mixes with fuel in the combustion chamber and when ignited creates a controlled explosion that propels the piston up and produces power.
Without air, the engine could not run or generate electricity. Therefore, the air intake system plays a crucial role in an engine’s performance.
Does A Cold Air Intake Give Great Sound To A Car?
Many car enthusiasts disagree on whether or not a cold air intake makes the car louder. One thing is for sure though, a cold air intake can definitely change the sound of your engine.
Increasing the amount of air drawn into the engine can produce a deeper, more aggressive tone that some people love. This is especially noticeable when starting the vehicle for the first time or when accelerating sharply.
While some people may find this attractive, others may not like the added noise. Ultimately, it all depends on your personal preference. Some cold air intakes are quieter than others, so it’s possible to find one that doesn’t make too much noise if you search.
Choosing a quality cold air intake system is critical to minimizing negative effects on engine noise.
How Does Cold Air Intake Make Car Louder?
When you install a cold air intake on your car, you are essentially removing the regular air filter and replacing that filter box with the aftermarket cold air intake. Additionally, cold air intakes are often designed with wider, softer tubes that allow for freer airflow.

This can cause the engine to make more noise as air is drawn through the intake system. The sound produced can be a deep, raspy growl that is more noticeable than the original air intake system.
It’s worth noting that increasing engine noise is not the primary goal of a cold air intake. Instead, the main goal is to increase the amount of cold air reaching the engine, which can improve performance.
Top Factor That Affects Car Loudness By Cold Air Intake
The noise from a car with a cold air intake can be affected by several factors, including the type of car, the type of cold air intake system, and driving conditions. The type of car can also play a role in the effect an intake of cold air has on the sound.
Cars with larger engines and more aggressive exhaust systems are often noisier to start with, so adding a cold air intake can make them even noisier. In addition, the design of the cold air intake can also affect the sound of the engine.

Some designs incorporate sound-deadening materials to reduce noise generated by the engine, while others are designed to amplify sound for a more aggressive tone. How you drive the car is also a big factor that affects the sound of your car.
When the engine is running under heavy loads or high speeds, it may generate more noise than under normal driving conditions.
Here Are Essential Ways To Make Cold Air Intake Louder
In addition to the cold air intake system, there are also many ways to get your car to sound well. Just follow the tips below and you will be able to make your car sound better.
1. Upgrade the Exhaust System
Installing a performance exhaust system can improve the sound and performance of your car. For example, a cat-back exhaust system can improve your car’s performance and give it a deep, aggressive exhaust note.
2. Headers
Headers are the octopus-like tubes that emerge from one if not both, sides of the engine block. They’re the first point your exhaust exits the vehicle, so it’s usually the first place a race car engineer tries to break down the drag in your car’s engine.

Because headers can improve flow, they also change the sound of your car’s exhaust system and can even increase performance.
3. Resonator Delete Kit
A resonator acts as a second muffler, softening the tone of your exhaust and limiting its sound. Once you get it out, you get all that extra smoothing off. Basically, these components can be compared to large echo chambers.
When installed into your stock or aftermarket exhaust system, it will give your vehicle a harsher, throatier tone and create a smoother path for the exhaust flow.
4. Exhaust Tips
Surprisingly, your exhaust tips can change the way your exhaust sounds. Changing the size or number of tailpipes can really change the sound that comes out of your car.
Exhaust tips come in all sorts of shapes and sizes, and changing them up can give you a more aesthetic look and better sound. Go crazy and throw big blast tubes or be subtle and stay small. The sound of your car will change completely.
Top FAQs About What Does A Cold Air Intake Sound Like
Does air intake makes the car louder?
Yes, with a cold air intake, the engine can receive a greater volume of air, which can increase engine noise during operation. Additionally, some cold air intakes are designed with a more open air filter element or larger diameter air tube, which can further increase intake noise.
