The 5.7L Hemi breathes well from the factory, but the stock airbox and restrictive paper filter leave throttle response and that deep V8 growl on the table. A quality cold air intake is one of the few bolt-on upgrades that frees up real airflow, sharpens part throttle response, and lets the engine sound the way a Hemi should. We focused on intakes built specifically for the 5.7 across the Ram 1500, Charger, Challenger, 300C and Grand Cherokee platforms.
We weighed filtration quality, tube design, heat shielding, fit and finish, and whether each kit holds a CARB EO number for emissions legal states. Some of these are oiled cotton, some are dry synthetic, and a couple are fully enclosed sealed boxes. Below are the seven we trust most for the 5.7 Hemi, ranked best first.

1. K&N 63 Series AirCharger Cold Air Intake (5.7 Hemi): Best Overall
The K&N 63 Series AirCharger is the intake we reach for first on a 5.7 Hemi because it nails the balance of airflow, fit, and long term value. The roto-molded tube is dimensionally consistent, the heat shield seals cleanly to the underside of the hood, and the High-Flow cotton filter flows far more air than the factory paper element while staying washable. On Ram 1500 and Charger applications we saw crisper throttle tip in and a fuller midrange without any drone on the highway.
The honest weakness is maintenance. The oiled cotton media needs cleaning and re-oiling every so often, and over-oiling is the classic mistake that can foul a sensitive intake air sensor if you are careless. If you prefer a truly zero fuss filter, a dry media kit lower on this list suits you better. But for outright performance with proven data and a CARB number on most fitments, the K&N earns the top spot.
- Mandrel style roto-molded intake tube tuned for the 5.7 Hemi airflow path
- Reusable High-Flow cotton gauze filter rated for roughly 100,000 miles between cleanings
- Molded heat shield with factory hood seal to pull cooler air
Pros: Strong, repeatable airflow gains backed by K&N dyno data; Million Mile limited warranty and washable filter mean it pays back over time; CARB EO number on most year and model combinations for emissions legal states
Cons: Oiled cotton filter requires occasional cleaning and correct re-oiling; Tone is moderate rather than aggressive if you want a loud setup
2. Spectre Performance Air Intake Kit (5.7 Hemi): Best Value
Spectre is the smart pick when you want real cotton filter airflow and a sharper Hemi note without paying for the premium badge. Owned by the same parent as K&N, Spectre shares the washable filter ecosystem, so cleaning kits and replacement media are everywhere. The aluminum tube looks great under the hood, the included heat shield does a respectable job blocking radiant engine heat, and install is a straightforward hand tool job on the 5.7.
Where it gives a little ground is sealing. The shield is good but not a fully enclosed box, so on a hot day sitting in traffic the filter sees more underhood heat than a sealed kit would. For most street drivers the difference is small and the airflow gain plus the added growl make this the best value intake on the list. Just verify emissions status for your specific year and chassis before buying.
- Polished or black powder coated aluminum intake tube for a clean engine bay look
- Reusable cotton air filter that flows well and washes for reuse
- Includes the hardware, couplers and shield needed for a no cut install
Pros: Delivers most of the airflow benefit of pricier kits with strong qualitative value; Backed by Spectre which is part of the K&N family, so filter support is easy; Noticeable intake growl under throttle that many Hemi owners want
Cons: Not as fully sealed from engine heat as a closed airbox design; Many fitments do not carry a CARB EO number, so check your state
3. aFe Power Magnum FORCE Stage-2 Cold Air Intake (5.7 Hemi): Best Performance
If your priority is squeezing the most airflow out of the 5.7, the aFe Magnum FORCE Stage-2 is built for it. The oversized roto-molded tube and large conical filter move serious air, and aFe publishes dyno sheets showing healthy horsepower and torque gains across the Hemi range. The sealed one piece heat shield is one of the better designs here, keeping the filter fed with cooler air pulled from outside the engine bay. You also get to choose between the Pro DRY S synthetic media for zero maintenance or the Pro 5R oiled cotton for the absolute peak flow.
The trade off is complexity and volume. This is one of the more involved kits to install, with more brackets and couplers than a simple drop in shield, so budget some time and patience. It is also loud, which is a feature for many Hemi owners and a drawback for anyone who wants a quiet cabin. Done right, it rewards you with the most aggressive breathing and sound on this list.
- Big bore roto-molded tube engineered for maximum 5.7 Hemi airflow
- Choice of Pro DRY S synthetic or Pro 5R oiled filter media
- One piece sealed heat shield with factory hood seal isolates the filter
Pros: Among the strongest airflow numbers in aFe dyno testing for the Hemi; Filter media choice lets you pick dry no maintenance or oiled for max flow; Excellent build quality and a deep, aggressive intake tone
Cons: Among the more involved installs with more parts to fit correctly; Aggressive sound may be louder than some drivers prefer
4. Airaid MXP Series Cold Air Intake (5.7 Hemi): Best Sealed Box
Airaid built the MXP around a fully enclosed airbox, and on the 5.7 Hemi that pays off as a steady, repeatable cold air feed. Because the filter lives inside a sealed box with a proper dam and seal, it is shielded from the radiant heat of the engine and pulls cooler air even when you are crawling through summer traffic. The roto-molded tube is well finished, and the SynthaMax dry media option means you can wash the filter and reinstall without messing with oil.
The flip side of that enclosed design is sound. If you bought an intake mainly to hear the Hemi roar, the MXP will disappoint you because the box keeps things relatively civilized. It also sits toward the upper end of the lineup in terms of value, so you are paying for the engineering. For an owner who wants consistent cold air, low maintenance, and a tidy under hood look over theatrics, it is an excellent choice.
- Fully enclosed sealed airbox isolates the filter from underhood heat
- Dam and seal kit blocks hot air for a true cold air feed
- Available with washable SynthaMax dry media for no oil maintenance
Pros: Enclosed box gives among the most consistent cold air feeds on the list; Dry filter option means no oiling and minimal upkeep; Clean, OEM-plus look that suits a subtle build
Cons: Enclosed design mutes the intake growl that some buyers chase; Premium kit that sits at the higher end of the range qualitatively
5. S&B Cold Air Intake Kit (5.7 Hemi): Best Filtration
S&B made its name on filtration that protects the engine while still flowing big numbers, and that reputation holds on the 5.7 Hemi. The sealed airbox keeps hot air out, and the clever clear view window lets you eyeball the filter condition without pulling anything apart. S&B publishes independent efficiency testing, which matters on a daily driver where dust ingestion over the years is a real concern. You can run the oiled cotton media for maximum flow or the dry media for fuss free upkeep.
The main caution is fitment. S&B coverage is deepest on the Ram and truck side of the Hemi family, so if you are on a car chassis double check that a kit is listed for your exact application. Replacement filters are also less likely to be on a parts store shelf than the K&N range, meaning you may order media online. Those are small prices for what is arguably the best engine protecting filtration in this roundup.
- Sealed airbox with a clear view window to check the filter without tools
- Independently evaluated high filtration efficiency to protect the engine
- Choice of oiled cotton or dry media to match your maintenance preference
Pros: Outstanding filtration efficiency verified by independent testing; Sealed box with view window is genuinely practical and well made; Strong airflow without sacrificing engine protection
Cons: Fitment coverage is broader on trucks than on every car chassis; Filter replacement media can be less common at local stores
6. Volant Cold Air Intake with PowerCore Filter (5.7 Hemi): Best Dust Protection
The Volant kit stands out for owners who take their Hemi anywhere dusty. Its fully enclosed airbox houses a Donaldson PowerCore filter, a media originally developed for heavy equipment, which gives it exceptional dust holding capacity and protection. On a Ram that sees gravel roads, towing in the dust, or light off road duty, that filtration is a genuine advantage, and the dry media means you never deal with oil at all. Just tap or rinse it and reinstall.
The downsides are sourcing and sound. PowerCore replacement filters are less common and cost more to replace than a standard cotton element, so factor that into long term ownership. The sealed box also keeps things quiet, so this is not the kit for someone chasing volume. For a working truck or a Hemi that lives in tough conditions, the Volant trades noise and easy filter availability for serious protection.
- Donaldson PowerCore filter offers excellent dust holding for dirty conditions
- Fully closed airbox isolates the filter from engine heat
- Dry media needs no oiling and simply taps clean or rinses
Pros: PowerCore filtration is a strong choice for dusty or off road use; Sealed box delivers a consistent cold air charge; Zero oil maintenance with a long service interval
Cons: PowerCore replacement filters are pricier and harder to source; Quieter tone and less of the classic intake growl
7. Injen PowerFlow Cold Air Intake (5.7 Hemi): Best for Sound
If you bought a Hemi partly for the noise, the Injen PowerFlow leans into it. The aluminum tube is tuned to amplify that deep intake bark under acceleration, and it genuinely makes the 5.7 sound meaner from inside and outside the cabin. Airflow is solid, the tube and finishes look sharp, and the washable MaxFlow filter keeps long term upkeep simple. Fit on the common Hemi platforms is good with hand tools and no cutting.
The compromise is the open style heat shield. It seals reasonably well but it is not a fully enclosed box, so on very hot days the filter sees more underhood heat than the sealed kits higher on this list, which can blunt the cold air benefit slightly. The sound that makes it fun around town can also wear on you during long highway stints. For a street Hemi built around character and tone, though, the Injen is the most fun pick here.
- Tuned aluminum tube that emphasizes a deep, aggressive Hemi intake note
- Heat shield with seal helps draw cooler air from the front
- Available in polished and black finishes to match your build
Pros: Among the most satisfying intake sounds for a 5.7 Hemi; Solid airflow gains and tidy, good looking tube design; MaxFlow filter washes and reuses for long service life
Cons: Open style shield seals less than a fully enclosed airbox; Sound can become tiresome on long highway drives for some
Frequently Asked Questions
Will a cold air intake add real horsepower to a 5.7 Hemi?
Yes, a quality cold air intake frees up airflow that the restrictive factory airbox and paper filter hold back, and most manufacturers publish dyno sheets showing modest but real gains on the 5.7 Hemi, often in the range of a handful of horsepower and torque, with the biggest improvement felt in throttle response and midrange pull. The gains are larger when the intake is paired with a tune, a cat back exhaust, or other supporting mods. On a completely stock engine the number on paper is small, but the sharper response and fuller V8 sound are immediately noticeable, which is why the upgrade remains a very popular first bolt ons for Hemi owners.
Do I need a tune after installing an intake on my Hemi?
For most quality bolt in intakes designed specifically for the 5.7 Hemi, you do not strictly need a tune because the kit is engineered to work within the factory sensor calibration, and the mass air or speed density system adjusts fueling automatically. That said, adding a tune unlocks noticeably more of the intake’s potential by optimizing the air fuel ratio and timing for the increased airflow, so if you want the maximum benefit, pairing the intake with a handheld tuner is the smart next step. Always pick an intake that retains the proper sensor location so the computer reads airflow correctly without throwing a check engine light.
Oiled cotton filter or dry synthetic filter for a 5.7 Hemi?
Oiled cotton filters like the K&N High-Flow generally flow the most air and last a very long time between cleanings, but they require correct cleaning and re-oiling, and over-oiling can leave residue on a sensitive intake air sensor if you are careless. Dry synthetic filters such as aFe Pro DRY S, Airaid SynthaMax, or Donaldson PowerCore need no oil at all, are simpler to maintain, and still flow well, which makes them ideal for owners who want to wash and reinstall with zero fuss. For most daily driven Hemis the dry option is the lower stress choice, while die hard performance seekers tend to favor oiled cotton for the last bit of airflow.
Is a cold air intake legal in emissions states like California?
It depends on the specific kit and your exact year and chassis, because emissions legal intakes carry a CARB Executive Order number, often shown as an EO number on the product listing. Brands like K&N hold CARB EO numbers on many of their 5.7 Hemi applications, which makes them street legal in California and other CARB states, while some open element and high flow kits do not carry that certification. Before you buy, look up the EO status for your exact application, since fitments vary by model year, and running a non certified intake in a CARB state can cause you to fail a smog inspection.
How hard is it to install an air intake on a 5.7 Hemi myself?
Most cold air intakes for the 5.7 Hemi are designed as no cut, bolt in jobs that a confident home mechanic can finish in roughly thirty to sixty minutes with basic hand tools like a socket set and screwdrivers. Simpler open element and heat shield kits are the quickest, while fully enclosed airbox designs and large diameter performance kits like the aFe Stage-2 have more brackets and couplers, so they take longer and demand a bit more patience to seal correctly. The key steps are transferring the intake air sensor carefully, seating every coupler and clamp fully to avoid unmetered air leaks, and confirming the heat shield seals against the hood before you drive.
Our Verdict
For most 5.7 Hemi owners, the K&N 63 Series AirCharger is the top pick because it blends proven airflow gains, a washable million mile filter, and a CARB number on most fitments, making it the safest all around upgrade for power, sound, and long term value. Our runner up is the Spectre Performance kit, which delivers most of that cotton filter airflow and a satisfying Hemi growl while offering the best qualitative value in this roundup. If you instead prioritize the most aggressive breathing, step up to the aFe Magnum FORCE Stage-2, and if dust protection or a fully sealed cold air feed matters most, the S&B and Airaid kits are excellent specialist choices.
