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 5-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.

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.

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.

  • Affordable
  • Directional cone filter

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.
