If you have a Dodge, Plymouth, or any other car with Hemi charged engine under the hood, you already are a sucker for speed. Riding at godspeed leaving everyone to eat your dust on the road is a feeling that gives you pleasure like no other.
And the Hemi never fails to do that. Yet, with time the power starts to fade. If not that, at least, you’re tired of the amount of fuel it burns. Not at all economical.
Whatever the case may be, that’s when you get the best cold air intake for a 5.7 Hemi charger for your car. But which one?
To get your answer, check the list below.
Top 10 Best Cold Air Intake for 5.7 Hemi Charger
Cold air intake offers a fresh breath of air to the car engine. It makes the engine feel good and makes it more active. That’s because it got more oxygen which lets the fuel explode like crazy to get those power-charged HP and torque that you want from your muscle cars. But which cold air intake is best for your 5.7 Hemi?
Let’s find out.
1. K&N Cold Air Intake Kit
To improve acceleration as well as uphill performance, you’ve got to turn to the K&N cold air intake.
The first thing you notice looking at the kit is that it gets made from quality material. Compared to the factory air filter that comes under the hood it is way better. And to prove the point it goes through Dyno-tests where it stands out to deliver 50% more airflow to the intake tube than the regular kit,
But breathing in more air doesn’t make it great. It is great because it provides cold air for combustion to make sure you get the HP you need—no warm air coming through it.
And not only the horsepower increases with it. You can even hear the car roar with louder noise which is the true goal of riding a Hemi charged muscle car.
One more thing that K&N does so well is that it keeps the contaminants from passing through the tubes and getting to the combustion chamber. That’s just a big no-no as it harms the performance and wrecks the engine big time.
With it, there is less filter cleaning required as you can wait for 100,000 miles before ever looking under the hood.
- Long service life
- Easy to install
- Requires less maintenance
- Improves HP and torque
- Protects engine
- Installation takes a lot of time
2. Mopar 77070044AC Cold Air Intake:
Next on the line is the Mopar cold air intake. First of all, you’ve got to love the quality of it. The intake tube and the cone filter on the Hemi are quite long-lasting.
No need to clean the filter that often.
The cold intake helps to get the cold air coming from the outside to improve the horsepower and torque generation of the engine. On top of that, it even improves the throttle response which lets you take full power of the Hemi engine.
Like the earlier one, this one also has a large cone filter that breathes in the air and filters it to provide dirt-free air to burn in the combustion chamber. That’s one of the reasons, you can enjoy better fuel economy using it as there isn’t any waste going around.
It makes the piston go up and down fast to get the wheels moving faster than the wind.
- Improves HP
- Directional cone filter
- Improves throttle response
- A bit hard to install
3. Airaid 351-210 Intake System with SynthaMax Dry Filter

Right off the bat, you can see the difference with this kit as it comes with a huge glass housing that holds the filter inside it. On that box, you will find an integrated tube seal that works to keep the intake tube from moving all places. At the same time, it works to keep the unwanted heat engine from getting to it.
The real astonishing fact that with the S&B filters cold air intake you get to pull in the airflow not one but from two inlets. One pulls in the air from the fenders while the secondary one, which is optional can also pull in the air from the side. Don’t want that, then the optional silicon plug is there to seal that end.
Numbers also show its worth as it gets 41.28% more airflow than the rest and the fuel efficiency is at a peak of 99.30%. Best part is that you won’t get those irritating check engine light anymore

Buying Guide for 5.7 Hemi Charger Cold Air Intake
Owning a car will need constant investment along the road. Most of them are spent to make the car more powerful and awesome. To do that, all the focus should be on the engine as it can be considered as the heart and powerhouse of a car.
An engine uses the heat generated by the burning gases to ensure the power supply. To ensure that the engine doesn’t overheat and is getting enough fresh air supply, a cold air intake system can be installed.
There is a couple of things you should keep in mind before buying a cold air intake system. I will try to point out some of the most crucial points below.
1# Check the Compatibility
First things first, check whether the air intake will fit with your car or not. There are different air intake systems available for different models of cars. Make sure you are buying the right one. For example, if you own a Hemi 5.7, check the size chart and look for Hemi 5.7. If it is on the list you are good to go.
2# Check the Filter
The filter is another crucial part of the air intake. As all the air is going to come through the air intake filter, it’s inevitable that the filter is going to get dirty. That’s why you need a filter that is washable and reusable. That way you will be able to use it for a long time.
3# Then the Housing
Funneling the air inside your Hemi engine is the responsibility of the intake housing and it will depend on the shape of the housing. The housing holds a limited amount of air. That’s why the straightness of it is important for taking cold air into the engine.
4# Heat Shield
The general purpose of a heat shield is to protect the coldness of the filtered air. The inside of the engine is hot when running so there is a chance that the cold air might gain some temperature rise. The heat shield stops that from happening. The more cold air will result in more power.
Those are the key points to remember before purchasing an air intake. Some other things you can look out for is how much increase the intake will bring in the horsepower, torque, and sound. Check that out and you will be able to get yourself a top-performing cold air intake system.
How much HP does a cold air intake add to the 5.7 Hemi?
Well, the answer to this question depends on several factors like your car model, its engine and obviously the cold air intake system. Generally, 1HP is being generated in every cubic inch whenever your Hemi 5.7 goes via a cold air intake.
So, you can assume that you will see a visible difference in your Hemi 5.7 horsepower if you go via a cold air intake procedure. The horsepower can be increased to 390 by maintaining the ideal process of cold air consumption.
How do I get more power out of my 5.7 Hemi?
Getting more power is possible by upgrading the power. You can upgrade the power by replacing both the air intake box and stock air filter and installing a cold air intake. As a result of upgrading, your engine will receive cooler air and the horsepower will be increased.
What are the basic tools required for a cold air intake process?
The cold air intake process will ask you a few tools. It is better to keep these tools in your garage so that you can do the process by yourself. Firstly, you will be needing a 3/4-inch wrench with a socket of 13mm. You will also need a 10mm socket and a screwdriver. Keep in mind that the screwdriver needed to be flat.
Apart from that, the ratchet in combination along with a 5/16-inch socked is used widely. Without it, an Allen wrench of 4mm and a 10mm wrench will complete the tool list needed for a cold air intake process.
How much time does it take to install a new cold air intake?
The answer to this question also depends. The time for installation mainly depends on your cold air intake. You will find some cold air intake that is very complicated. This type of cold air intake will ask you to spend some time while installation.
On the other hand, your experience level also matters while you talk about the time needed for installation. You will be able to do it within 30 minutes if you are experienced. Otherwise, you may have to spend about 2 hours to install if you are a newbie.
Does a cold air intake need to be tuned?
Well, tuning is probably not mandatory as you are talking about a small change only in the overall flow.
