What is Cold Air intake System (CAI)?
Let’s start by understanding the function of air intake systems.
Cold air intakes play a crucial role in enhancing the performance of a vehicle. While this may be common knowledge, it is important to understand how they work.
A cold air intake system facilitates better combustion by increasing the quantity of colder air that is drawn into the engine. Traditional air intake systems have various flow restrictions, such as tubes, bends, and turns, which gradually slow down the incoming air, causing more resistance, increased temperature, and a reduced amount of oxygen to be delivered to the combustion chamber. As a result, the fuel-rich air/fuel mixture may not ignite properly, leading to a decline in performance over time.
However, a cold air intake system eliminates these restrictions and allows for the intake of colder air or a greater volume of oxygen, thereby maximizing combustion in the engine and increasing the performance of the vehicle.

Benefits of Using Cold Air Intake
In this section of Cold air intake buying guide, we will explore the benefits of installing a cold air intake in your vehicle. Let’s dive in!
#1 Power/Hp Gain :
A significant advantage of installing a cold air intake in your vehicle is the increase in power or horsepower. When more air or oxygen is available for combustion, the engine is able to create a more efficient fuel-to-air ratio, which leads to improved ignition of the fuel-rich air/fuel mixture. This, in turn, results in increased power output or horsepower for your vehicle.
The reason behind this is that colder air is denser than warmer air, and denser air contains more oxygen. By drawing in colder air from outside the engine bay, the cold air intake system provides the engine with a higher concentration of oxygen, which is necessary for the combustion process.
When the engine is able to receive more oxygen, the fuel is burned more efficiently, leading to a more powerful combustion stroke. This, in turn, increases the power output of the engine, resulting in a noticeable improvement in horsepower.
It is important to note that the exact amount of horsepower gained will depend on various factors such as the type of vehicle, engine size, and the quality of the cold air intake system installed. However, it is generally accepted that installing a cold air intake will provide some noticeable increase in horsepower, making it a popular upgrade for car enthusiasts and anyone looking to improve their vehicle’s performance.
#2 Increased Throttle Response :
An additional benefit of installing a cold air intake in your vehicle is the increase in throttle response. Over time, it is not uncommon for vehicles to experience a decrease in performance, particularly during tough terrain or when accelerating from a stop. However, by improving air flow and combustion within the engine, a cold air intake can significantly improve throttle response.
When you press down on the gas pedal, the throttle body opens up to allow air into the engine. With a cold air intake, the engine is able to receive a greater amount of cooler and denser air, which contains more oxygen. This increased supply of oxygen allows for more efficient combustion, resulting in a quicker response from the engine when the gas pedal is pressed.
In addition, a cold air intake system also reduces the restriction on airflow that is often present in factory-installed air intake systems. This means that the engine can receive a greater volume of air with less effort, resulting in quicker and more responsive acceleration.
#3 Boosted Mileage or Fuel economy : By using performance cold air intake you are basically increasing your gas mileage. As better oxygen level means better combustion and rick fuel/air mixture will burn properly and you get more energy out of every drop of fuel hence increasing mileage.
You will see 1-2 Miles per gallon increase in your mileage but along with this you have to maintain your driving habits also as in if you’re driving hard using extra power and acceleration that will surely not lead to increase in mileage. So be cautious about that.

Cold Air Intake Buying Guide – FAQs
Q.What is cold Air Intake?
Ans. A Cold air intake kit is replacement or aftermarket part that is designed to provide the engine with greater capacity of cooler air. Cold Air intake provides improved combustion rate by drawing in colder air. There are many flow restrictions by means of tubes, bends and turns that basically slower down the incoming air for combustion with time. More restrictions mean more resistance and temperature and less air or oxygen delivered to combustion chamber causing a poor ignition of fuel rich air/fuel mixture. This leads to decrease in performance with time.
Cold air Intake system is designed to free up those restrictions and drawing in colder air or more oxygen and maximizing combustion in your engine and hence increasing performance of your truck.
Q. Why Cold Air Intake is important for the engine?

This means better combustion and less fuel is needed to create the spark and run the engine which leads to better horsepower, torque and fuel economy. Moreover, it increases the efficiency of the engine also. In this Buying guide for Cold air intake we have covered detailed benefits for CAI.
Q. Does cold Air intake make any difference in performance?
Ans. Yes, Cold Air Intake do make a difference in performance. Some manufacture claims as much as 20-30 HP increase. But you will easily get 15-20 increase in horsepower and noticeable economy increase. And, if you’re using other modifications also like better performance exhaust, Tuners or suspension then you will create a much more efficient system.
Q. How often should I replace my cold air intake filter?
Ans. It depends upon the type of air filter you’re using. If you’re using Oiled filter that is re-usable and will last longer than the dry filter. So, it depends upon your cold air intake system.
Q. How many types of Cold Air intakes are there And Which is better cold air intake or Short Ram?
Ans.There are generally three types : the short ram system , Ram Air intake and the true cold air intake system.There is a 4th one also that we’ve covered in this cold air intake buying guide above.
Short ram system: The short ram is basically replace your factory intake with a new smooth pipe and an open element air filter .It is easy to install and cheaper than cold air intake.Since it takes place as your factory pipe so it allows for engine heat to have an easier path into your intake system, creating less horsepower and torque as compared to cold air intake. Its design tends to require less “plumbing” or fabrication work.
True cold air intake: Whereas Cold Air intake or The “true” cold air intake places an emphasis on moving the air filter as far forward as possible. It draws air from outside the engine bay to give engine cooler and denser air. It produces more supplemental cold air flow than the short ram design. Due to the intake having more piping, the cold air is usually more expensive, and more difficult to install.
Ram Air Intake: The Ram Air Intake is pretty much similar like cold air intake only the difference is – it comes with longer tubes and air filter at the back of system. This is more beneficial during high speeds as it draws larger volume of air with wind pressure which results in more engine power. It is somewhat like turbocharger but with less parts.
It’s depend upon you which air intake you want to buy, as from the name Short Ram intake provides short path which results in better throttle response. Moreover, it draws air from inside the engine bay which is much warmer and better for complete combustion of fuel which means short ram intakes gives better gas mileage also than cold air intake.
Whereas on the other hand Cold Air intake draws in cold and denser air that means more oxygen available for combustion which leads to more power. On the other hand, sometimes Short Ram intake gets issue like its intake pipe gets heated up due to engine heat- for that you need heat shield installed in the Short Ram Intake.
Q. Does a cold air intake damage your engine?
Ans. There is a bigger concern with air intake to your vehicle – that is hydrolocking or hydrolock. It is the condition in which engine takes in water instead of air, causing engine damage. As water gets trapped in the cylinder of the engine and it doesn’t compress also which can ruin the pistons and cause connecting rods to bend and damage the engine. But this is very rare case nowadays.
This have happened in past but now it’s very rare thing to happen as now the cold air intake comes with air bypass valve installed in the middle of the cold air intake. The high pressure of bypass valve would not allow water to engine your engine. The other option is you can choose short ram intake, so there is no option for hydro-lock.
We recommend if you’re living in area where the raining is very common than you should choose short ram intake.
Q. How Much a good cold air intake cost?
Ans. Changing from your vehicle’s intake system to Cold Air Intake system will cost around $150 to $550, depending upon the system. The cost is worth it actually , as you will save on fuel and your engine will get more power and better working.
Q. Why my cold intake pipe becomes very hot or what is heat Soak?
Ans. If your intake pipe is becoming hot very frequently then this is condition of heat soak in which the intake pipe itself heats up and it also increase the temperature of air going into your engine, decreasing engine performance. This is the issue usually with low grade air intakes. A good intake system is made from material such as aluminium that doesn’t allow the piping to get hot enough to effect performance.
Q. Does you need any tune with a cold air Intake?
Ans. Cold Air intake itself is best option to get more power and better mileage. Whereas if you want more advanced modifications then you should go with Tuners or Programmers, performance Exhausts, Suspensions and in trucks tonneau covers for better overall efficiency.
Q. Why some air intakes are cheaper than the others? If this really makes any difference?
Ans. First of all it totally depends upon your budget and system, which one you have to choose. But choosing cheaper one does not gives you that performance like the normal air intake. The cheaper air intakes usually come with simple design with a pipe and cheap filter and there is no testing for proper air/fuel mixing resulting in poor performance whereas the best Air intake comes with proper design and testing that mix air and fuel in proper ratio for better combustion and efficiency.
