Do Cold Air Intakes Increase Horsepower

Do cold air intakes increase horsepower ?

A commonly believed principle is that cool air has high density hence higher oxygen per unit volume than warm air.

When starting to modify a car, you can start with cold air intake modification. It is a popular mode of transformation since it is less costly and easy to install. The most important thing is that cold air intake gives a good amount of horsepower yet is affordable.

So, does intake of cold air increase horsepower?

Yes, cold air intake increases horsepower.

It helps make air sucked by the engine cooler by moving its air filler far from the engine.

Cold air has more oxygen, which allows the car to run better with the same fuel amount.

Do you want your car to be quick and better?

 Then it would be best if you opened its airflow up. Cold air intake can be a small investment but pays off big.

What is Cold Air Intake?

Cold Air Intake is an aftermarket assembly of parts that help draw in cool air into your car combustion engine.

Most cars manufactured in the ’70s and ’90s have thermostatic systems of the air intake, which assist in regulating the air temperature entering the engine.

Unfortunately, with the rising emission regulations and controls, and the advancement in technology, modern automobiles lack the thermostatic air intake and are fitted with a standard air intake that draws in unregulated cold air.

When the engine is cold, the system provides warm air gives cold air in the instances the engine is warm.

Thermostatic system of air intake helps ensure maximum performance, fuel economy, and efficiency.

You have probably heard that installing an intake of cold air system provides your vehicle with more horsepower.

To some extent, it is true, but ultimately performance gain depends on the vehicle and the type of performance intake system installed.

A traditional mode of performance intake depends on a heat shield to block the air filler from taking in warm engine bay air.

The traditional system thereby increases performance by changing the air quality that enters the engine.

How Much Horsepower Does a Cold Air Intake Add?

Most are the times you wish your car could run better than it already does. Is that your worry?

Then if you want your car operating better, the first thing you should do is open up your car’s airflow. It is excellent when starting modification.

Cold air intake might seem like a small investment, but it has a huge reward.

Opening up the cold intake of air can make a very significant impact.

So, how much horsepower can you can from cold air intake?

The process of redirecting the filter to pave the way for cooler air might seem simple, but it is crucial in adding 5 to 20 ponies of horsepower in most vehicles.

In addition, cold air intake improves your fuel efficiency and makes the engine sound even better.

However, it is essential to understand that the results you gain from this process of cold air intake depend on the type of vehicle and your choice of the intake system of the cold air.

How to Install a Cold Air Intake

When you understand how to install a cold air intake system yourself, you will cut many costs and save some dollars.

The first step you take before starting the process is choosing the right cold air intake brand. There is a variety to choose from, so be keen to look for reviews about performance.

You can easily install your cold air intake. So, once you choose the brand, here are the steps to installing cold air intake.

  1. Ensure you cool your engine enough to touch.
  2. Remove your battery cable from the negative terminal.
  3. Disconnect your cold air intake.
  4. Take the silicone coupling and attach them to the throttle body.
  5. Tighten a hose clamp at the end to make sure the silicone coupling is secure.
  1. Add a hose clamp before the silicon, but don’t tighten it.
  2. In the intake pipe that runs from the throttle bay and away from the engine, you can now insert the intake tube in the coupling silicon.
  3. Ensure you secure every bracket on the intake tube and tighten the silicon.
  4. You can now connect the mass airflow sensor into the modified system of cold air intake.
  5. Connect your battery once more.
  6. You can now enjoy the new power boosts!

Cold Air Intake Pros and Cons

The intake of cold air has both negative and positive results. It depends on its function the expected performance of the engine.


1. Longer Life for the Engine

The engine, which has colder temperatures, has a longer life span. Other benefits add up to the engine components like the radiator.

2. Increase in horsepower

As a result of the conduciveness of cold air to burning fuel, when you install cold air intake,  it helps the horsepower of the engine increase.

3. Lead To a Better mileage

When you use a cold air system to allow cold air intake, the air to fuel ratio to the gas line gets better. It, therefore, results in better mileage because the mixture burns more effectively.

4. Quicker throttle response

Upon pressing the gas pedal from a complete stop, it sends warm air from the intake of stock air producing a slow engine response. On the other hand, cold air input gives room to enter cooler air into the chamber. Therefore, enabling faster engine response than the stock intake.

5. Savings on filters

It is easier to wash and reuse an air filter using cold air intake when adequately lubricated.

Thus, it saves you money because you don’t have to exchange it for covering 15,000 miles, unlike using a paper filter.


1. Filter’s type

When using cold air intake, it allows you to use any filters. For instance, foam filters give more horsepower but are likely to be affected by the engine’s crowding of dirt and debris.

2. The Shape

Cold air intake permits a curve of 90 degrees which offsets the idle of your vehicle. The problem is that it sucks air into the car’s engine hence causing air to roll. It is likely to happen if combined with various modification components.

3. Impact

The meter is affected by the rolling effect of air, thus leading to an inaccurate reading of your engine. Consequently, it throws off the accurate air to the mixture of fuel hence allowing your machine to stop.

4. Hydro-locking concerns

Hydro-locking is the process that permits trapping in the cylinders. Upon absorbing moisture instead of air, the engine compromises the components in the cylinders.

Therefore, you end up ruining your pistons by permitting the bending of the rods responsible for connecting.

Final Thoughts

If you are always wondering how to make your car run better, open up your vehicle’s airflow. Cold air intake increases the mileage of your vehicle. It can be a simple and a small investment yet efficient and yield you great rewards.

Therefore when you start modifying your car, you should up a cold air intake system.

However, please note that the results you get will depend on the type of cold air system you use and the model of your car.
