Buying Guide

When you purchase a cold air intake (CAI), there are several factors you’ll need to keep in mind to ensure that you get a quality product that meets your needs. By keeping these factors in mind, you can be sure to choose a cold air intake that will give you the performance you need.

Filter Quality

The first thing to consider is the quality of the filter. Cold air intake filters are designed to capture a higher percentage of dirt and debris than a stock air filter, so it’s important to choose one that is durable and stands up to the rigors of use.

If the cold air intake filters aren’t of high quality, these particles will cause wear and tear on engine components, leading to costly repairs or even engine failure. A high-quality filter will help prolong your engine’s life by keeping these particles out. 


You’ll also need to inspect the capability of the cold air intake you are getting. Make sure it can flow the air your engine needs, as this will help ensure optimal performance.

Housing for Air Filter 

Pay attention to the housing for the air filter. A well-designed housing will help protect the filter from dirt and debris and make it easier to clean and maintain. There are a few different types of housings, but the most popular are made from aluminum or plastic. So, it is important to choose a house made from durable material to keep the cold air flowing into the engine.

Ease of use

Consider the ease of use when picking a cold air intake for your 5.7 Hemi challenger. It should be easy to install and maintain, so you can keep your vehicle running at its best. 


How much horsepower does a cold air intake add to a 5.7 Hemi?

Does a cold air intake add any significant change of Horse Power to the 5.7 Hemi? The answer, unfortunately, isn’t as straightforward as we would like. While many studies and dyno tests have been done on the subject, the results can vary greatly depending on the car, the type of cold air intake, and even the weather.

That being said, most folks agree that a cold air intake will add between 5 and 10 horsepower to your bone stock 5.7 hemi challenger. And that’s a pretty significant increase, especially if you’re starting with a stock engine.

But dyno testing has shown that a typical cold air intake installation on the 5.7 hemi challenger can increase horsepower by about 5-15 HP if you also go through other tunings required for optimal results of CAI installation. 

How much HP does a cold air intake Add to a challenger?

The thing about cold air intake is that the more powerful your engine is, the less impact a cold air intake will have. So if you’ve got a Hellcat-powered Challenger, don’t expect a massive power boost from a cold air intake. But if you’ve got a less powerful engine, a cold air intake can help wake it up.

The increase will be greater on naturally aspirated engines (not forced induction) and on” bottom-breathing” engines where the air filter is located near the ground. On the other hand, the power gain from a CAI will be less on “top-breathing” engines where the air filter is high near the engine’s throttle body.

Which is better: S & B or K&N cold air intake?

If you are looking for increased Airflow and more efficient filtration within budget, then the S&B is the better choice. However, if you are looking for better horsepower and torque, then the K&N is the better choice.

The K&N cold air intake has been shown to increase horsepower by up to 5% and torque by up to 7%. It is also said to improve throttle response and acceleration. The K&N, on the other hand, has been shown to improve airflow by up to 40%.

Is plastic or aluminum better for cold air intake?

So many cold air intakes are now manufactured with plastic materials rather than aluminum because plastic is less likely to corrode than aluminum. This is important because the last thing you want is your cold air intake to start rusting!

Also, plastic is lighter than aluminum so it won’t add as much weight to your car. This is important because a more lightweight car will be more fuel-efficient.

Lastly, plastic is a better insulator than aluminum. This means it will keep the cold air in and the hot air out, making your car’s engine run more efficiently.


So, which cold air intake should you pick for the 5.7 Hemi challenger? From my experience, selecting either the S & B or K&N cold air intake will do the job for your 5.7 Hemi challenger. If you have a few more bucks, you can get the Mopar cold air intake. 

For those confined within a budget, even the Airaid Cold Air Intake System can also be a great pick.
