Does a Cold Air Intake Actually Work?

If you are thinking about installing cold air intake and you wonder, do cold air intakes work? We offer you a clear answer for that question.

A cold air intake is believed that it is a valuable addition to your vehicle that can make a significant difference in driving performance.

As an owner of a car, you may consider installing a cold air intake. A cold air intake is believed that it is a valuable addition to your vehicle that can make a significant difference in driving performance. Since every car owner wants to upgrade the car’s power and general performance, it comes to changing the new part of the car such as exhaust systems, bolt-on accessories. But the downside of it is the high cost you have to pay for it. A cold air intake is a fairly economical modification and easier to install than most other engine modifications. So do cold air intakes work or not? Let’s find out the truth about cold air intakes here!

What Is Cold Air Intake?

First of all, let’s talk about the definition and the function of a cold air intake.

Cold Air Intake (CAI) is usually an aftermarket assembly of parts used to bring relatively cool air into a car’s internal-combustion engine. The CAI will not add a lot of power to your engine like other engine modifications but it helps your engine in some ways.

An interesting example to help you understand better the function of cold air intake is cold. Think about when you have a cold that clogs up your head and restricts your breathing. Then go running, you will feel better right? So cold air intake is like a medicine for your engine, letting your engine finally breath.

Cold air intakes move the air filter outside of the engine compartment so that cooler air can be sucked into the engine for combustion. Cooler air brings more oxygen into the combustion chamber, and that means more power. The filters are usually moved to the upper wheel well area, or near a fender where there is more access to free flowing, cooler air, and less heated air from the engine.

How Does Cold Air Intake Work?

Before going to know “do cold air intakes really work”, it’s necessary to know how do cold air intakes work. Actually, the way it works is similar to the human lungs. 

At first, air passes through a much larger performance air filter. The filter uses a depth loading design to remove more dirt from air, then keep it trapped inside a matrix of sticky cotton fibers. The matrix of sticky cotton fibers allows a high volume of air to always be able to pass through. After that the air is cleaned, it flows into a wider intake tube. The tube typically has completely smooth interior surfaces, and less restrictive curves. By that, a cold air intake system can always feed the engine a high volume of turbulence-free air.

The air filter is situated so that it can collect the coldest air. It often requires a special heat shield to prevent warm engine bay air from entering the system. But a front mounted ram air intake will relocate the air filter to a high-pressure zone outside of the engine compartment so it can collect the coldest air as possible and the high air pressure forces more air into the system as the speed increases. By improving the airflow dynamics, a front mounted cold air intake system is able to deliver more horsepower.

So Do Cold Air Intake Really Work?

As you already know how do cold air intake work, the answer is much clearly that YES, a cold air intake really works. 

In order to make power, the cylinders have to inhale air to create the explosion that produces wheel-turning horsepower and torque. Since cold air contains more oxygen molecules than warm air, injecting a higher volume of oxygen-rich air into the cylinders allows the engine to burn fuel more completely during the combustion cycle. This “combustion efficiency” results in an increase of horsepower and torque, using roughly the same amount of fuel.

In summary, there is no doubt that installing the CAI, the engine is able to burn the fuel more completely and result in additional horsepower. You can check with some specialist in your trustful garage, they have a lot of knowledge about maintenance tips so they will give you more evidence for this statement.

The Benefit Of Cold Air Intake

It’s obviously your expected answer from us for the question “do cold air intakes work”. We are now introducing to you some benefits of this modification. 

1. Better Mileage

Thanks to the cold air intake, the air fuel ratio is optimized. With the engine receiving a sufficient amount of oxygen, the vehicle is bound to provide better mileage. Otherwise, in the case of an insufficient amount of oxygen, the vehicle will burn more fuel to compensate for less oxygen. 

2. More Horsepower

The amount of air used during the combustion cycle is one of the factors that determine an engine’s output. The cold air allows us to burn fuel more efficiently, compared to hot air. That’s why installing cold air intake can help to increase horsepower.

3. Enhanced The Sound

The cold air intake helps to improve the engine performance. By that it increases the amount of air sucked in by cold air intake and as the result, more intense air flow produces that throaty growl, desired by many vehicle owners.

4. Increased Acceleration

By installing cold air intake, you can feel the acceleration better than before. The engine is likely more responsive. So most people who enjoy speedy acceleration prefer to install CAI.

Sum Up

It is all about do cold air intakes work. It’s obviously a helpful answer for you and you can think about it when deciding to modify your car. Do not forget to follow our maintenance tips for better repairing your car.
