Cold Air Intake for 5.7 Hemi – Buyer’s Guide and FAQ
A cold air intake (CAI) is one of the best modifications you can make to your Charger to improve its performance. There are many different CAIs on the market, so it can be difficult to decide which one is right for you. But let’s discuss what exactly is the function of CAI.
What is a Cold Air Intake?
A Cold Air Intake is a type of car engine modification that most car-enthusiasts believe to be a great way to increase horsepower. Basically, it simply allows the engine to breathe better by allowing cooler air from outside the vehicle into it.
What is the fuction of Cold Air Intake?
A cold air intake replaces the factory air box and air filter with a high flow part that draws in cooler outside air. Cooler, denser air is more oxygen-rich than warm air and allows your car to make more power and do it in a cleaner, more efficient way. You might be thinking: if less restriction means better performance, why not just go with the biggest intake pipe possible? The answer is that this would actually hurt performance since the engine needs to be able to build up enough vacuum in the intake for proper air/fuel metering and combustion.
Manifold vs. Short Ram
Manifolds are cast aluminum or plastic formulations that are intended to guide airflow through the engine. They are often heavier and made of material that is not as “breathable” as other materials. Short Ram Intakes are manifolds but with a specially designed tube that brings in outside air directly into the engine compartment. This increases horsepower because cooler air enters naturally due to lower temperatures, allowing combustion at a lower temperature. The cooler the air, the more oxygen it contains; therefore, there is more available for combustion, meaning higher horsepower.
What about CAI vs. CAE?
Cold Air Exhaust is very similar to a Cold Air Intake but its function is reversed: exhaust gases are fed into the intake manifold (which is why people refer to it as “after-market”). These systems work on the same principle of delivering cooler outside air into the engine for greater oxygen levels and, thus, more power.
What about CAI vs. SRI?
Short Ram Intake is very similar to a Cold Air Intake but its function is reversed: outside air is taken in via the engine compartment rather than the front. SRI’s are often made of lighter materials, work better with turbochargers because they are lightweight, and sometimes even function better with superchargers because heat is not produced by the rotating impeller attached to the engine itself.
What about cold air intakes vs cold air exhausts?
Cold Air Intake systems are always better than Cold Air Exhaust systems because they deliver fresh air directly to the engine, whereas Cold Air Exhaust delivers exhaust gases back into the intake.
When is a cold air intake not needed?
A cold air intake is only necessary if your car was originally equipped with an aftermarket or stock system that did not have this function. V8’s and V6’s usually require aftermarket intakes because they are not designed to breathe as efficiently as an engine with eight cylinders.
What other types of engine modification should I get?
If you want to maintain your factory warranty, get performance exhaust or headers instead of cold air intake. If you’ve got the money to get both, it’s highly recommended by car enthusiasts.
How much horsepower does a cold air intake gain?
On average, anywhere from 10-30 horsepower is gained, depending on the engine type and size. A lot of modern cars correctly equip themselves with their stock intakes to ensure that enthusiasts are not tempted to modify their car beyond factory specifications set forth by the manufacturers.
How much horsepower does a cold air exhaust gain?
On average, anywhere from 10-30 horsepower is gained, depending on the engine type and size. A lot of modern cars correctly equip themselves with their stock intakes to ensure that enthusiasts are not tempted to modify their car beyond factory specifications set forth by the manufacturers.
Where is a Cold Air Intake located?
The cold air intake attaches to the front of the engine and collects cooler air, resulting in better airflow. It allows hot, dense air from around the radiator’s front grille to be displaced by outside, cooler air. This results in more power and efficiency after installation. So, the location of a cold air intake is behind the driver’s side front wheel and one inch below the cowl under the hood.

Choosing the Cold Air Intake
Choosing the best cold air intake for a 5.7 Hemi Charger can be difficult when comparing the many different ones available in today’s aftermarket engine tuner market, but it doesn’t have to be. The key is knowing what you need and want out of your cold air intake system in details in order to make a well informed decision based on the many choices available to you.
Choosing the right Cold Air Intake is important to get the best performance for your vehicle. There are a few things that you need to consider before you choose an intake:
- Size of air filter – The larger the surface area of the filter, more air can be pulled from outside of your car. However, if there is too much surface area, drag on your car engine will increase as there is more material for drag. If drag on your engine increases substantially it will decrease gas mileage and horsepower output. Make sure to purchase one with a suitable size for maximum efficiency while minimizing drag.<br>
- Durability – To ensure that an intake will last long without breaking down, make sure that the intake is made of high quality materials. It should also have a good warranty to cover any defects.<br>
- Availability – Make sure that it is easy to find an aftermarket Cold Air Intake for your car’s make and model. If you cannot easily order one online, look for one specific to your vehicle at local stores or dealerships.
The 5.7 Hemi Charger is a V8 engine equipped with variable valve timing for both intake valves and exhaust valves. It discharges air through an advanced composite cold air intake system with high-flow characteristics, which results in better performance at all speeds, greater fuel economy, and a substantial decrease in air intake temperatures.
In general, cold air is denser than hot air, which offers the advantage of lower intake air temperatures for improved engine performance. Cold air also offers a higher oxygen concentration level per unit volume for increased horsepower.

When should you change the Cold Air Intake
The Cold Air Intake ensures that your engine receives cooler air than it would from outside by placing its opening in front of the radiator instead of behind it like other intakes do. This way airflow can flow smoothly and not get stuck between the cars frame and fender like behind-the-radiator intakes tend to do.
The air filter in your 5.7 Hemi Charger is meant to keep debris out of the engine and to prevent any particles from entering it that could cause damage. The cold air intake filters the incoming air, which ensures that only clean air gets into your engine where it can be used. This makes sure that your engine doesn’t receive too much or not enough air—which both result in poor performance, driveability issues, and reduced gas mileage.
It is recommended that you change your cold air intake on your 5.7 Hemi Charger every year or 15,000 miles. The air filter inside the Cold Air Intake should be replaced every 30,000 miles (recommended life of the vehicle). If you drive in dusty conditions such as construction sites and unpaved roads, it is advisable to replace the filter at least once a year or 15,000 miles.
Cold Air Intake Failure Symptoms
Sometimes your old air intake system may not be working as well for you as it used to, and it’s time to get a new one. But when? This is a very common question, so here are some tips to help you know when it’s time to change your air intake system.
- The most obvious sign that you need a new cold air intake is that your car is no longer running as efficiently as before. You may notice sluggish performance and gas mileage decrease when there’s something wrong with your intake system.
- A loud whistling noise coming from the engine bay means that your cold air intake isn’t sealed properly with the rest of your engine. If this is happening, you need to replace your cold air intake because it will compromise the performance of other parts in the long run. Your vehicle suddenly has trouble starting up right away. A new cold air intake can help extend the life of your engine by reducing the amount of carbon build-up inside. With a good filtration system, your car’s engine will not have to work as hard to operate, which means it will last longer. A dirty cold air intake system will decrease gas mileage and make your vehicle run less efficiently.
- You notice debris in/around your cold air intake. If you find leaves, twigs, bugs, and other kinds of debris in your cold air intake system, this means that it’s not as well-sealed as it should be. Debris can enter the engine when the seal is compromised.
- You hear an unusual sound coming from your engine once you reach a certain speed. While driving around 50 mph (80kph), if you hear loud whistling sounds coming from your engine bay it could mean that there’s something wrong with your cold air intake system. You may also here this noise when accelerating to higher speeds on the highway or during races at the drag strip.
Check engine light comes on with an inspection or oil change. If you are at the mechanic’s office and they tell you that one of the reasons for your poor performance is because of a dying cold air intake, then there’s no doubt that it’s time to get a replacement before something serious happens.
How to change Cold Air Intake yourself
First thing’s first – get everything together that you’re going to need before you start this process! You can grab all of these items at any local auto parts store or online retailer:
- A socket wrench with various sized sockets (usually 13mm and 14mm)
- New Cold Air Intake Kit
- Extension Tube (this is often sold separately from the kit but you can normally pick up an extension tube for this specific intake at whichever store you purchase your intake from)
- zip ties
All right, now that you’ve got everything together. You’re ready to get started! Here are the steps to changing the cold air intake on your car:
Step 1.
Start by opening the hood of your vehicle. Make sure you don’t have anything directly over it to prevent something from falling down into the engine – if this happens, you’ll need to remove whatever fell down in order to get back under there! Once it’s opened, get out of the vehicle and make sure all doors are closed before continuing.
Step 2.
Remove any heat shielding or covers that may be blocking where the new intake is supposed to go. Keep in mind that the type of new intake you get may be different than our specific one.
Step 3.
Remove the old intake by unscrewing, unclipping, or unscrewing any parts that are holding it into place.
Step 4.
Once this is done, attach the extension tube to the open end of your new cold air intake and then tighten any screws necessary with your socket wrench to keep it securely in place on both ends (the fan belt should still be intact if you have an older vehicle). Once all four screws are tightened (two on each side), make sure everything is secure before re-attaching heat shields/covers – you don’t want anything rattling loose after you just put in this new cold air intake!
Once that’s all complete, simply close the hood of your car and enjoy the benefits of your hard work!
Step 5.
Replace shields/covers if any were removed during installation.
Step 6.
Close the Hood.
Now that you know how to change a cold air intake on your own, keep these things in mind for indicators of whether you need to change it again!
