The 5.7L HEMI in the Dodge Challenger R/T loves to breathe, and the factory airbox is the single biggest restriction holding it back. A good cold air intake opens up the path to the throttle body, sharpens throttle response, and unlocks that deep induction growl every R/T owner wants when the secondary throttle plates snap open. The gains are modest on paper, usually a handful of horsepower, but the change in how the car feels and sounds is anything but subtle.
We pulled together the seven intakes that R/T owners actually trust, weighing real fitment on the 5.7 HEMI, filter quality, how each one manages heat soak, and whether it triggers a check engine light or needs a tune. Whether you want a sealed airbox that genuinely pulls cold air or an open element that screams under the hood, there is a pick here for your build.

1. K&N 63 Series AirCharger Cold Air Intake (Dodge Challenger 5.7L): Best Overall
The K&N 63 Series AirCharger is the intake we recommend to most Challenger R/T owners because it gets the fundamentals right. The roto-molded intake tube is mandrel smooth on the inside, and the sealed heat shield mates against the hood seal so the filter draws cooler air from the fender and grille area rather than radiator heat. That sealed design is what separates a real cold air intake from a noise kit, and it shows up as more consistent power on warm days when an open filter would be choking on heat soak.
Where it earns its top spot is the combination of CARB legal status and no tune required, which means you bolt it on, reset nothing, and drive without a check engine light. The honest weakness is the oiled cotton filter. If you over oil it during a clean and reinstall, residue can foul the MAF sensor and cause rough idle or a code, so you have to be disciplined with the recharge kit. Treat the filter correctly and this intake will outlast the car.
- Sealed one-piece heat shield blocks engine bay heat from the filter
- Washable and reusable cotton gauze filter rated for one million miles
- Direct bolt-on fit with no tune required and no check engine light
Pros: CARB legal in all 50 states so it passes emissions; Genuine throttle response and induction sound improvement; Lifetime warranty and reusable filter lowers long term upkeep
Cons: Cotton filter needs careful oiling or it can read the MAF sensor wrong; Sound is deeper but not as aggressive as a fully open element
2. aFe Power Momentum GT Cold Air Intake (Dodge Challenger 5.7L HEMI): Best Sealed Airbox
If your main goal is cold air and not noise, the aFe Momentum GT is the most thorough sealed system you can bolt onto a 5.7 R/T. The entire filter lives inside a roto-molded box with a clear top window, and it seals to the hood so the only air it can pull is fresh and cool. On back to back warm weather pulls, a sealed box like this holds power better than an exposed cone because intake air temperatures stay low, and that is the whole point of the upgrade.
The choice between the oiled Pro 5R and the oil free Pro DRY S is a real advantage, since the dry media completely sidesteps the MAF fouling problem that worries new intake buyers. The trade off is sound. Because the filter is enclosed, the Momentum GT is noticeably more reserved than an open element setup, so owners chasing a loud growl will find it tame. For drivers who want clean power and a clean engine bay, that quietness is a feature, not a flaw.
- Fully enclosed roto-molded airbox with a clear viewing window
- Choice of oiled Pro 5R or oil free Pro DRY S filter media
- Large diameter intake tube increases airflow over the stock airbox
Pros: Best in class heat isolation thanks to the fully sealed box; Dry filter option removes any MAF over oiling risk; Premium fit and finish that looks factory engineered
Cons: Quieter than open intakes because the box muffles induction sound; Pro 5R oiled media still needs occasional cleaning
3. Mopar Cold Air Intake Kit (Dodge Challenger 5.7L): Best OEM Fit
The Mopar kit is the safe and sensible choice for R/T owners who want a genuine improvement without stepping outside the Dodge ecosystem. Because it is engineered by the same people who built the car, fitment is flawless, every bracket lines up, and there is zero guesswork about clearances or sensor placement. It bolts to the original mounting points and runs without a tune, so it is about as low risk as an intake upgrade gets.
The honest caveat is that this is a conservative design. You get cleaner airflow and a slightly richer induction note, but the gains are smaller than what a fully sealed aftermarket airbox delivers, because Mopar prioritizes refinement and warranty friendliness over maximum flow. Filter servicing is also a little awkward since the cone sits close to the strut tower. If confidence and OEM credibility matter more than chasing every last bit of power, this is the kit for you.
- Engineered by Dodge for guaranteed factory fitment and clearances
- Uses original mounting points for a true bolt-on install
- Conical filter and smooth tube improve flow without a tune
Pros: Perfect fitment because it is the factory designed part; Keeps you inside the dealer comfort zone for warranty conversations; Clean install with no fabrication or trimming
Cons: Modest gains compared to aftermarket sealed systems; Filter access can be tight against the strut tower
4. Spectre Performance Cold Air Intake (Dodge Challenger 5.7L HEMI): Best Value
Spectre, which is part of the K&N family, builds the intake for R/T owners who want most of the benefit without the premium outlay. You get a polished aluminum intake tube, a washable conical filter, and a heat shield that mounts to factory points for a genuinely easy install. On the dyno and on the street it wakes up the throttle and adds a satisfying induction roar, which is exactly what most people are buying an intake for.
The compromise is in heat management. The shield does a decent job, but it is not the fully enclosed box you get from aFe, and the aluminum tube can soak up some engine bay heat in stop and go traffic. In real driving that difference is small, and for a no tune bolt-on that delivers sound, response, and a reusable filter, the Spectre is the value benchmark every other intake here gets measured against.
- Mandrel bent aluminum tube with a built-in heat shield
- Washable and reusable red cotton conical filter
- Bolt-on install using factory locations with no tune
Pros: Strong sound and response gains for the money; Reusable filter keeps long term running costs low; Simple install most owners finish in under an hour
Cons: Heat shield is not as fully sealed as premium airboxes; Aluminum tube transfers some underhood heat
5. Injen Power-Flow Cold Air Intake (Dodge Challenger 5.7L): Best Throttle Response
Injen has a reputation for tuned intake tubes, and their MR Technology bump near the MAF housing is designed to keep airflow smooth and the sensor reading accurately. On the 5.7 R/T that translates into the sharpest seat of the pants throttle response in this group, the kind you feel the first time you roll onto the gas after install. The dry filter is a bonus for anyone nervous about cleaning and oiling cotton media down the road.
The flip side of that aggressive airflow is sound. The Injen is one of the louder intakes here, and at steady highway cruise it can introduce a low drone that some commuters find tiring on long trips. The heat shield seals well but stops short of being a closed box, so on the hottest days it gives up a little to the aFe. For owners who prioritize immediate response and a louder character, the Power-Flow delivers.
- MR Technology tuned tube design smooths and increases airflow
- Heat shield isolates the filter from radiator and engine heat
- Dry filter media avoids any MAF over oiling concerns
Pros: Crisp throttle response that owners notice immediately; Dry filter means no oiling and no fouling risk; Quality powder coated tube finish
Cons: Louder drone at cruise may bother some daily drivers; Heat shield seal is good but not a fully closed box
6. S&B Filters Cold Air Intake (Dodge Challenger 5.7L HEMI): Best Filtration
S&B made its name building intakes for dusty truck applications, and that filtration pedigree carries over to the Challenger. The sealed airbox pairs with a large pleated filter that has been independently evaluated for dust efficiency, so you get cold air and serious engine protection at the same time. For an R/T that sees gravel roads, track days, or just a lot of miles, that filtration headroom is genuinely reassuring.
The drawback is selection and character. S&B focuses its catalog more heavily on diesels and trucks, so Challenger specific fitments and dress up options are thinner than what K&N or aFe offer, and you may need to confirm your exact application. The sound bump is also mild because of the sealed box, which suits owners who want clean power but underwhelms anyone chasing a loud growl. If protecting the engine is your top priority, S&B earns its place.
- Sealed airbox design with a large surface area filter
- Independently evaluated high dust holding capacity and efficiency
- Oiled cotton or dry media filter options available
Pros: Outstanding filtration efficiency protects the engine; Sealed box keeps intake air temperatures low; Generous filter size means long service intervals
Cons: Fewer Challenger specific options than the big intake brands; Subtle sound increase that quiet seekers like but enthusiasts may not
7. Airaid MXP Series Cold Air Intake (Dodge Challenger 5.7L): Best Big Bore Tube
The Airaid MXP is for the R/T owner who is thinking ahead to bolt-ons and wants intake tubing that will not become the bottleneck. The roto-molded tube is noticeably larger in diameter than most rivals, which gives high rpm airflow room to grow as you add a tune, headers, or an exhaust. Paired with the sealed intake dam, it pulls cool air while making a satisfyingly aggressive noise when the throttle opens up.
That generous tube is also the main compromise. The Challenger engine bay is tight, and the big bore Airaid can crowd nearby components, so you want to test fit carefully and route everything cleanly. The dam seals well but is not a fully enclosed box, so heat soak protection trails the aFe and S&B systems. For a stock R/T the extra tube volume is more potential than realized gain, but for a car on a modification path the MXP is a smart foundation.
- Oversized roto-molded intake tube for maximum flow volume
- Sealed intake dam directs cool air to the filter
- Choice of dry SynthaMax or oiled red cotton filter media
Pros: Largest diameter tube in the group for top end airflow; Dry filter option for zero oiling maintenance; Aggressive induction sound at wide open throttle
Cons: Big tube can crowd an already busy engine bay; Sealed dam is effective but not a fully closed airbox
Frequently Asked Questions
Will a cold air intake add real horsepower to my Challenger R/T?
Yes, but keep your expectations grounded. On a stock 5.7L HEMI R/T, a quality cold air intake typically adds a handful of horsepower and a bit of torque, usually in the single digits at the wheels. The bigger, more noticeable changes are sharper throttle response and a deeper induction sound. The intake really shines as part of a package. Once you add a tune, an exhaust, and a throttle body upgrade, the freer flowing intake lets those parts work to their full potential, and the cumulative gains become meaningful.
Do I need a tune after installing a cold air intake on my R/T?
For the intakes on this list, no tune is required to run them safely, since they are designed to keep the mass airflow sensor reading correctly out of the box. Your 5.7 HEMI will adapt within its factory fuel trims. That said, a custom tune is strongly recommended if you want to unlock the full value of the intake. The factory computer is conservative, and a tune lets it take advantage of the extra airflow for cleaner power delivery. Think of the intake as tune ready rather than tune dependent.
Will a cold air intake throw a check engine light or fail emissions?
A properly installed, correctly oiled intake should not trigger a check engine light. The most common cause of a code is an over oiled cotton filter contaminating the MAF sensor, which is why dry filter options are popular. For emissions, look for a CARB Executive Order number, like the one the K&N 63 Series carries, which makes it 50-state legal and emissions compliant. If you live in a strict emissions state, choosing a CARB certified intake is the safest way to stay legal at inspection time.
Is a sealed airbox better than an open cone filter on a Challenger?
For consistent power, yes. A sealed airbox like the aFe Momentum GT or S&B isolates the filter from hot engine bay air, so intake temperatures stay lower and the car makes more reliable power on hot days. An open cone filter usually sounds louder and more aggressive but is more prone to heat soak in traffic, where it can pull warm air. The right choice comes down to priorities. Choose a sealed box for cold air and stable power, or an open element if maximum induction sound is what you are after.
How hard is it to install a cold air intake on a Challenger R/T?
It is a very beginner friendly modifications you can do. Every intake here is a bolt-on that uses factory mounting points and basic hand tools, with no cutting or fabrication needed. Most R/T owners finish the job in thirty minutes to an hour, even on their first time. The key steps are disconnecting the battery, carefully transferring the MAF sensor without touching its element, and making sure every clamp and connection is fully seated so there are no vacuum leaks. Take your time and the install is straightforward.
Our Verdict
For most Challenger R/T owners, the K&N 63 Series AirCharger is the top pick because it nails the balance that matters, a genuinely sealed heat shield, no tune and no check engine light, and CARB legal status that keeps you compliant in every state, all backed by a lifetime warranty. If your priority is the coldest possible air and the cleanest engine bay, the aFe Power Momentum GT is the runner up, offering the most thorough fully sealed airbox in the group along with a dry filter option that removes any MAF worry. Pick the K&N for the best all around package, or the aFe when maximum heat isolation is the goal.
