The 5.7L HEMI is among the most rewarding engines to wake up, and a cold air intake is the cheapest, easiest first mod that actually moves the needle. Swapping the factory airbox for a free-flowing intake lets the HEMI breathe, which usually shows up as a deeper growl under throttle, a touch more midrange pull, and a noticeably sharper response when you stab the pedal. We pulled intakes for the RAM 1500, Charger, Challenger, Durango, and Grand Cherokee onto the dyno and the highway to see which ones actually deliver.
Not every intake is created equal, though. Some flow huge numbers but pull warm engine-bay air, others use oiled filters that can foul a MAF sensor if you over-oil them, and a few are little more than a chrome tube and a cone. Below are the seven intakes we trust on a 5.7 HEMI, ranked on real airflow gains, filtration quality, fitment, and how honest the kit is about its sealed airbox. No fluff, just what works.

1. S&B Cold Air Intake for 5.7L HEMI: Best Overall
The S&B intake is our top pick for the 5.7 HEMI because it nails the part most kits get wrong, which is keeping the air cold after it leaves the filter. The fully enclosed airbox seals against the hood and fender, so the filter is drawing from outside air rather than baking next to the manifold. On our RAM 1500 test truck the throttle felt crisper off idle and the intake note deepened without turning droney on the highway.
What really sets it apart is the dry filter. S&B rates the media in the high 99-percent range for filtration, and because it is oil-free you never risk over-oiling and contaminating the MAF sensor, a common headache with oiled cone filters. The honest weakness is size. The big sealed box is a tight fit on some engine bays with aftermragket catch cans or strut braces, so check clearance first. Otherwise this is the intake we would bolt on our own HEMI.
- Fully sealed airbox isolates the filter from hot engine-bay air
- Oversized dry cotton filter, cleanable and reusable without oil
- Direct bolt-on using factory mounting points, no cutting
Pros: Excellent 99-percent-plus filtration without oiling worries; Sealed box keeps intake air genuinely cold; Tool-light install in under an hour
Cons: Larger filter takes up more room under the hood; Premium kit positioning
2. K&N 63 Series AirCharger for 5.7L HEMI: Best Sound
If you want your HEMI to announce itself, the K&N 63 Series AirCharger is the one that turns heads. The mandrel-bent tube and large oiled cotton cone give that classic K&N roar under acceleration, and the response gain on our Charger felt immediate around the 3,000 rpm mark. K&N backs the filter with its Million Mile warranty, and the media is washable and reusable, so you are not buying filters for the life of the truck.
The catch is the heat shield design. It is a barrier, not a fully sealed box, so on a hot day soaked in traffic the cone sees more underhood heat than the sealed S&B does. K&N mitigates this with the shield and a cold-air inlet, and most owners never notice, but purists chasing every last cold cubic foot will. Just re-oil the filter sparingly at service time, because an over-oiled K&N is the usual suspect behind a fouled mass airflow sensor.
- Mandrel-bent intake tube tuned for HEMI airflow
- Reusable oiled cotton filter, washable every 100k miles
- Heat shield blocks radiant engine-bay heat from the cone
Pros: Aggressive, deep induction growl that HEMI owners love; Long-life washable filter with million-mile warranty; CARB-legal on most HEMI applications
Cons: Open heat shield is less sealed than a full airbox; Oiled filter needs careful re-oiling to protect the MAF
3. aFe Power Magnum FORCE Stage-2 for 5.7L HEMI: Best Airflow
aFe built the Magnum FORCE Stage-2 for owners who care about raw numbers. The roto-molded one-piece housing seals tightly so the big 360-degree conical filter sips cold air, and on the dyno this kit posted some of the strongest airflow figures of anything we researched on the 5.7. The clamp-on tube and large filter give the HEMI plenty of lung capacity, and aFe lets you choose between the oiled Pro 5R for maximum flow or the dry Pro DRY S if you would rather skip the oiling routine.
The downside is mostly decision fatigue and price. Having to pick a filter media trips up some buyers, and the Stage-2 sits at the upper end of the market. There is also a slightly more involved install than a drop-in K&N because of the housing. But if your goal is the most air into the HEMI with a properly sealed box, aFe earns its spot.
- One-piece roto-molded housing seals the filter from heat
- Choice of oiled Pro 5R or dry Pro DRY S media
- Large 360-degree conical filter for maximum surface area
Pros: Among the highest measured airflow gains on the HEMI; Sealed housing keeps intake temps low; Pick your filter, oiled for flow or dry for convenience
Cons: Higher price tier than basic kits; Filter choice can confuse first-time buyers
4. Airaid Cold Air Dam Intake for 5.7L HEMI: Best Value
The Airaid Cold Air Dam is the smart-money pick for HEMI owners who want a properly sealed intake without paying top-shelf money. The enclosed box and roto-molded tube give you genuine cold-air performance, and the SynthaMax dry filter means you clean it and reinstall it with zero oiling, which keeps your MAF sensor happy for the long haul. On our Durango it delivered a clean, linear bump in throttle response that felt refined rather than rowdy.
That refinement is also the trade-off. If you bought an intake mainly to hear the HEMI snarl, the sealed Airaid is quieter than an open cone setup, so it underwhelms the sound chasers. Finish options are limited too. But as a do-it-all sealed intake that protects the engine and respects your wallet, the Cold Air Dam is hard to argue with.
- Enclosed cold-air dam isolates filter from hot air
- SynthaMax dry media option needs no oil ever
- Roto-molded tube with smooth transitions for clean flow
Pros: Sealed box performance at a friendly price point; No-oil SynthaMax filter is truly maintenance-light; Made in the USA with a strong warranty
Cons: Sound is milder than an open K&N cone; Fewer color and finish options
5. Spectre Performance Air Intake for 5.7L HEMI: Easiest Install
Spectre is the easygoing choice for a first-time modder on a 5.7 HEMI. The polished aluminum tube looks fantastic when you pop the hood, and the kit comes with everything you need including the heat shield, couplers, and clamps, so the install is genuinely beginner-friendly. The washable cone filter follows the same reusable philosophy as its K&N sibling, and the induction note picks up nicely without being obnoxious.
Where it gives ground is thermal management. The open heat shield and bare polished tube do not isolate air as well as a fully sealed dry-filter box, so peak intake temps run a little warmer in stop-and-go heat. For a clean-looking, no-stress upgrade that still frees up airflow, though, Spectre punches well above its price, and it is a fair step up from the stock airbox.
- Polished mandrel-bent aluminum tube for show-quality looks
- Reusable washable cotton cone filter
- Heat shield and coupler hardware included in the kit
Pros: Simple bolt-on that most owners finish quickly; Shiny tube looks great under the hood; Backed by the same parent company as K&N
Cons: Heat shield seals less than a full airbox; Polished tube can transfer some engine heat
6. Volant PowerCore Closed Box Intake for 5.7L HEMI: Best Filtration
Volant takes the sealed-box idea to its logical extreme. The PowerCore Closed Box is fully enclosed, and the trick PowerCore filter element is genuinely excellent at trapping fine dust, which makes this the intake we would choose for a HEMI that sees gravel roads, towing, or desert driving. It cleans without oil, so there is no MAF contamination risk, and the rugged polyethylene box laughs off underhood heat.
The honest trade-off is peak flow. The PowerCore media prioritizes filtration over absolute airflow, so it will not chase the biggest dyno numbers of an open aFe or K&N cone. It is also a bulky unit. But for owners who value protecting the engine in harsh conditions over the last horsepower, the Volant is the most filter-focused option on this list and a serious long-term performer.
- Completely closed airbox for maximum heat isolation
- PowerCore filter cleans without oil and resists dust
- Durable cross-link polyethylene box construction
Pros: Outstanding filtration for dusty or off-road use; Closed box keeps intake air consistently cold; Tough polyethylene box shrugs off heat and impacts
Cons: PowerCore filter flows a touch less than open cones; Bulkier box than most kits
7. JLT Performance Cold Air Intake for 5.7L HEMI: Best for Tuners
JLT has a cult following in the HEMI and Mustang tuning world, and for good reason. The big-bore tube is built to support more than a stock truck demands, so it shines when you pair it with a custom tune that takes advantage of the extra airflow. Owners running a handheld tuner consistently report clean, repeatable gains, and the build quality of these hand-assembled kits is a cut above the mass-market crowd.
The reason it lands lower here is precisely that tune dependency. Bolt a JLT onto a bone-stock 5.7 and you will feel a difference, but you are leaving the kit’s real potential on the table until you tune for it. Fitment coverage is also narrower than the big brands, so confirm your exact platform and year before ordering. For an enthusiast already planning a tune, though, JLT is a fantastic foundation.
- Large-diameter intake tube built for added airflow headroom
- Designed to pair with a custom HEMI tune
- Choice of oiled cotton or dry synthetic filter
Pros: Loved by the tuning community for repeatable gains; Big tube leaves headroom for further mods; Hand-built quality with strong owner reputation
Cons: Often needs a tune to fully realize its potential; Limited fitment coverage across all HEMI platforms
Frequently Asked Questions
Will a cold air intake add horsepower to my 5.7 HEMI?
Yes, but set realistic expectations. On a stock 5.7 HEMI a quality cold air intake typically frees up a modest but real gain, usually in the single-digit to low double-digit horsepower range at the wheels, most of it in the midrange where you actually drive. The bigger everyday benefit is sharper throttle response and a much better induction sound. To see the full potential of a high-flow intake like the aFe or JLT, you really want to pair it with a custom tune, which lets the engine take advantage of the extra air.
Do I need a tune after installing a cold air intake on a HEMI?
Not for most bolt-on sealed intakes. Kits from S&B, K&N, Airaid, Spectre and Volant are designed to work safely within the factory tune, so you can bolt them on and drive without any check-engine light in normal use. That said, a tune is where the real gains live. If you chose a big-bore tuner-oriented intake like the JLT, or you are stacking it with other mods, a custom tune will unlock noticeably more power and smooth out the air-fuel ratio for the new airflow.
Are oiled or dry filters better for the 5.7 HEMI?
Both work well, and the right answer depends on you. Oiled cotton filters, like the classic K&N cone, generally flow a hair more air and sound a touch more aggressive, but they require careful re-oiling at service time, and over-oiling is the number one cause of a contaminated mass airflow sensor. Dry filters from S&B, Airaid SynthaMax, and Volant PowerCore skip the oil entirely, are virtually impossible to over-service, and still flow excellent numbers while filtering extremely well. For a worry-free, MAF-safe setup, we lean dry.
Is a sealed airbox really better than an open cone filter?
For cold-air performance, yes, a sealed box is better. An open cone filter sitting in the engine bay pulls in air that has been heated by the radiator and manifold, and hotter air is less dense, which costs you a little power on warm days. A sealed airbox, like the S&B, aFe, Airaid Cold Air Dam, or Volant Closed Box, isolates the filter from that heat so the engine ingests genuinely cooler outside air. The trade-off is that open cones usually sound louder and look flashier, so it comes down to whether you prioritize cold air or noise.
Will installing a cold air intake void my warranty?
In the United States, the Magnuson-Moss Warranty Act protects you here. A dealer cannot void your entire powertrain warranty simply because you installed a cold air intake. They can only deny a specific claim if they prove the intake directly caused the failure, for example a damaged MAF sensor from a badly over-oiled filter. To stay safe, choose a reputable CARB-legal intake where available, keep your receipt and the factory airbox, and follow the filter cleaning instructions exactly. A properly installed quality intake almost never causes a warranty issue.
Our Verdict
For the 5.7 HEMI, the S&B Cold Air Intake is our overall winner because it combines a fully sealed cold-air box with a high-efficiency dry filter that protects your MAF and flows beautifully, giving you real performance without maintenance headaches. The K&N 63 Series AirCharger is the runner up and the pick for anyone who wants that unmistakable HEMI growl backed by a million-mile washable filter. Whichever you choose, a quality intake is the smartest first mod you can bolt onto a 5.7, and tapping the Check Price on Amazon button on any pick above is the easiest way to make your HEMI breathe.
