What is a cold air intake system?

Installing a cold air intake system of your vehicle is one of the more inexpensive modifications you can make but it can provide a big impact on performance.

A cold air intake system helps to feed cold air into the engine of your vehicle. This cooler air is brought into the engine to help with combustion and this can result in more power and performance. Essentially it helps to cool down the engine with free-flowing air so that it doesn’t overheat and can stay at a consistent temperature for longer.

With the addition of cold airflow and a more regulated temperature you will notice a performance boost in terms of horsepower and torque and in other areas too. These kits also mean that you remove the box that surrounds the air filter in your vehicle and with the larger and straighter tubes so you can get more air into your vehicle’s engine.

Types of intake systems

While we are going to look specifically at the best cold air intake system, this isn’t the only type of intake system you can buy. There are several out there that we should make you aware of.

Short ram air intake

This type of air intake system is manufactured so that the entire intake system that has been factory-installed in your vehicle is replaced.

The big difference between a short ram air intake system as a cold air intake system is that the tubes on the short ram intake kit are shorter. This makes it ideal for use in smaller spaces and if the air filter is located closer to the engine.

You won’t get air that is as low a temperature as you get with a cold air intake system but it can be a better choice for vehicles where you don’t have a whole lot of space for upgrades.

Ram air intake

A ram air intake is quite similar to a cold air intake system in that it will flow cool air into your engine.

The difference is that the air filter is located at the back of the system next to the engine and the tubes are longer too. You will also find a pre-filter in many of these systems which is found at the front of the tubes. The reason for this is that it can help provide an additional layer of protection against debris, dust, and water.

Signs your air intake system is faulty

Even if you aren’t a mechanic or experienced with vehicle maintenance, there are some tell-tale and common signs that your air intake system is faulty and needs to be replaced. This can be a good indication that it is time to invest in a cold air intake system for added performance and reliability.

Best Intake Systems

Engine is overheating

This is one of the most obvious signs that the factory-installed air intake system isn’t working properly. If your engine is overheating then it usually means that not enough air is getting into it so that it cools down properly.

You will probably see a warning light on your dashboard that indicates that your engine is getting too hot.

Strange engine noises

Another common sign that an air intake system is failing is that you will hear unfamiliar noises coming from the engine.

Strange noises could happen due to a number of reasons such as needing to have the radiator replaced however a fault in the air intake system can be the root cause too. Installing a cold air intake system can help remedy this problem and also ensure that the engine temperature is kept consistent.

Decrease in performance

If you are finding that your vehicle isn’t providing the same level of performance as before in terms of speed, horsepower, and torque, you may need to upgrade the intake system.

It can also be notified if you go off-road and have trouble getting out of and moving around on surfaces that your vehicle would otherwise have no issues with. This could include sand, dirt roads, and other rough terrains.

You’re using more fuel

If your air intake system is failing, your vehicle will try to take in more air and use more fuel as a result.

A sign that your air intake system needs to be replaced and upgraded is if you are using more fuel than you usually would but you aren’t going any further. Poor fuel efficiency and miles per gallon can be a result of a number of problems but the intake system trying to compensate for not taking in enough air is one of them.

What to look for when buying a cold air intake system

We’re going to have a look at the best cold air intake system you can buy to upgrade the factory components in your car. There are some things you should consider and look out for before you dive in and make a purchase.

Some places – such as California – have strict rules on modifications that impact vehicle emissions so make sure you check this out for where you live. Failing to do so can result in a fine.
  • Longevity – Compared to some other vehicle modifications, a cold air intake system is fairly easy to install. It might not be as simple as spark plugs for example but it is easier than other parts however you don’t want to have to replace it frequently. This is why you should consider the longevity of the system in terms of how long you would expect to get good performance from it before it needs to be replaced.
  • Filtering dust and debris – Cold air intake systems come with a filter to help prevent dirt, dust and debris from infiltrating the system. If you regularly drive off-road and in less than ideal conditions you may want to consider a system that has a more advanced filter.
