A cold air intake is one of the simplest bolt-on upgrades you can make to a RAM 1500, and on the 5.7L HEMI it is also among the most satisfying. The factory airbox is built to be quiet and cheap to produce, not to feed the engine. Swapping in a larger filter and a smoother tube lets the V8 breathe, sharpens throttle response, and unlocks that deep intake growl that RAM owners love. We spent time with the most popular kits on Amazon to sort the genuinely worthwhile ones from the loud-but-hollow crowd.
Below are seven intakes that fit the modern RAM 1500, covering the 5.7L HEMI, the 3.6L Pentastar V6, and the 3.0L EcoDiesel where noted. We weighed filtration quality, how well each kit seals heat out, fitment fuss, and whether you actually feel a difference behind the wheel. Whether you want a sealed, dyno-tuned system or a budget kit that still flows hard, there is something here for your truck.

1. K&N 63 Series AirCharger Cold Air Intake (RAM 1500 5.7L HEMI): Best Overall
The K&N 63 Series AirCharger is the intake we kept coming back to for the RAM 1500. The big reason is the sealed roto-molded airbox. A lot of cheaper kits leave the filter hanging open in the engine bay, where it happily sucks in hot air off the radiator and headers. K&N seals the filter inside a one-piece box with a dedicated inlet, so the truck pulls cooler, denser air. On the 5.7L HEMI that translates into a crisper tip-in and a noticeably eager mid-range when you roll into the throttle on an on-ramp.
It is not perfect. The oiled cotton-gauze filter rewards you with long life and great flow, but you have to maintain it correctly. Cleaning and re-oiling is a once-every-few-years job, and if you slather on too much oil you can foul the mass airflow sensor and trigger a check engine light. Done properly it is a non-issue, but newer owners should read the instructions carefully. For filtration, sealing, and proven results, this kit earns the top spot.
- Sealed one-piece heat shield airbox blocks hot engine bay air
- High-flow oiled cotton-gauze filter washable up to roughly 100,000 miles
- Mandrel-formed intake tube with smooth bends for steady airflow
Pros: Genuine throttle-response gain you can feel on the HEMI; Fully enclosed box keeps intake air temps low; CARB-exempt so it stays legal in emissions states
Cons: Oiled filter must be cleaned and re-oiled, not just rinsed; Over-oiling can foul the MAF sensor if you are careless
2. S&B Cold Air Intake (RAM 1500 5.7L HEMI, Dry Cotton Filter): Best Filtration
If your priority is protecting the engine while still flowing big numbers, the S&B kit is the one to study. S&B publishes independent filtration efficiency data, and its filters consistently land in the very high 99 percent range, which matters a lot on a truck that sees dusty job sites or gravel roads. The fully enclosed airbox seals out hot air just like the K&N, and the clear lid is a genuinely smart touch because you can glance at the filter condition without pulling anything apart.
The dry cotton filter option is the headline feature for many RAM owners. It cleans with simple compressed air and a rinse, so there is no oil to over-apply and no risk of contaminating the MAF sensor. The trade-off is size and fitment. The box is substantial, and if your engine bay is crowded with a secondary battery or aftermarket wiring you may need to tidy things up. It also commands a premium, but the filtration credentials justify it for many buyers.
- Fully sealed airbox with a see-through lid to check the filter
- Choice of dry cleanable cotton or oiled cotton filter media
- Independently lab-evaluated for very high dust efficiency
Pros: Outstanding filtration backed by published efficiency testing; Clear lid lets you inspect the filter without tools; Dry filter option means no oil and no MAF worries
Cons: Larger box can be a snug fit alongside other accessories; Premium kit that sits at the upper end of the range
3. aFe Power Magnum FORCE Stage-2 Cold Air Intake (RAM 1500 5.7L): Best Power Gains
aFe built the Magnum FORCE Stage-2 around airflow, and it shows. The large diameter tube and oversized conical filter move serious air, and aFe backs the kit with dyno charts showing real horsepower and torque gains on the 5.7L HEMI. The one-piece roto-molded housing doubles as a heat shield, so you keep most of the cold-air benefit while feeding the engine more than the factory box ever could. On the road the truck pulls harder up top and sounds the part doing it.
That sound is also the main caveat. The Stage-2 is one of the louder kits we sampled, and while many RAM owners chase exactly that, a few find it droning on long highway stretches. You also get the usual choice between the Pro 5R oiled filter, which flows beautifully but needs periodic re-oiling, and the Pro DRY S synthetic, which trades a hair of flow for zero oil maintenance. Pick the dry media if you want a quieter maintenance life.
- Roto-molded one-piece housing with integrated heat shield
- Choice of Pro 5R oiled or Pro DRY S synthetic filter media
- Large diameter intake tube for maximum airflow on the HEMI
Pros: Strong dyno-proven airflow and horsepower gains; Aggressive intake sound that suits the RAM personality; Filter media choice covers both oiled and dry preferences
Cons: Louder than some owners expect at cruising speed; Pro 5R oiled filter needs the usual re-oil routine
4. Spectre Performance Air Intake Kit (RAM 1500 5.7L HEMI): Best Value
The Spectre kit is the one we point budget-minded RAM owners toward. It uses a washable conical cotton-gauze filter and a polished aluminum tube, so you get the reusable media and the dressed-up engine bay look without paying for a full sealed airbox. Install is genuinely beginner friendly, using factory mounting points and hand tools, and most people have it on the truck and growling within an hour. For the money, the throttle response bump and the added induction sound are easy wins.
The honest weakness is heat management. This is an open-element design, so the filter sits more exposed to engine bay temperatures than the enclosed K&N or S&B boxes. Spectre includes a heat shield, but it does not seal as completely, which means intake air temps creep up more in stop-and-go traffic. If you want the look, the sound, and a real filter upgrade at a friendly price, it delivers. If you are chasing the lowest possible intake temps, step up to a sealed box.
- Washable and reusable conical cotton-gauze filter
- Polished aluminum intake tube for a clean engine bay look
- Bolt-on install using factory mounting points and basic tools
Pros: Excellent value while still using quality washable media; Easy install that most owners finish in under an hour; Bright, satisfying intake growl from the HEMI
Cons: Open-element design is less sealed than enclosed airbox kits; Filter sits closer to engine bay heat
5. Airaid MXP Series Cold Air Intake (RAM 1500 5.7L HEMI): Best Sealed Box
Airaid’s MXP Series splits the difference between an all-out airbox like the S&B and an open kit like the Spectre. You get a fully sealed MXP box that isolates the filter from engine heat, paired with the option of the SynthaMax dry synthetic filter. That dry media is a big draw for RAM owners who do not want to mess with filter oil. Clean it with low-pressure air and reinstall, no re-oiling, no MAF anxiety. Airaid builds these in the USA and backs them with dyno testing, so the gains are real rather than marketing.
Where it asks a bit more of you is installation. The sealed box has a few more steps than simply swapping a filter onto a tube, and you will spend a little longer routing and sealing everything correctly. The intake note is also more restrained than the loud aFe or Spectre kits, which some owners actually prefer. If you want sealed-box performance with low-maintenance dry filtration, the MXP is an easy recommendation.
- Fully sealed MXP airbox isolates the filter from hot air
- SynthaMax dry filter option needs no oil at all
- Dyno-evaluated kit manufactured in the USA
Pros: Sealed box delivers consistent cool air to the HEMI; Dry SynthaMax filter is genuinely no-fuss to clean; Solid build quality and tidy fitment
Cons: Slightly more involved install than open-element kits; Sound is milder than aggressive open intakes
6. Roush Performance Cold Air Intake (RAM 1500 5.7L HEMI): Best Bolt-On Fit
Roush brings a motorsport pedigree and an OE-quality mindset to its RAM 1500 intake, and that shows in how the kit fits. Everything lines up with factory precision, the enclosed airbox looks like it could have come on the truck, and there is no tune required. You bolt it on, reconnect the sensors, and drive. For owners who want a performance intake without any compromise in build quality or any fear of fitment surprises, this is a confidence-inspiring choice.
The flip side of that refined approach is that the gains feel more measured. Roush prioritizes clean integration and a quality reusable filter over headline-grabbing airflow numbers, so the throttle improvement is there but more polished than dramatic. You should also confirm availability for your exact model year and engine, because Roush coverage is not as broad as the universal-favorite brands. If a flawless bolt-on with brand prestige is what you want, it is worth seeking out.
- Enclosed airbox design for cooler, denser intake air
- Reusable high-flow filter for long service life
- OE-quality direct bolt-on fitment with no tune required
Pros: Clean factory-grade fit and finish; No tuning needed, true plug-and-play install; Reputable performance brand backing the kit
Cons: More understated gains than the most aggressive kits; Availability for specific RAM trims can vary
7. K&N 77 Series High-Flow Performance Intake (RAM 1500 5.7L HEMI): Best Sound
The K&N 77 Series is the kit for the RAM owner who wants to hear the truck. Built around a polished mandrel-bent aluminum tube and an open oiled cotton-gauze filter, it produces the deepest, most pronounced induction growl in this group. The aluminum tube also looks fantastic under the hood, giving the engine bay a real performance presence. You still get K&N’s well-proven washable filter that lasts for many tens of thousands of miles between cleanings, so the upgrade is durable as well as loud.
Because it uses a heat shield rather than a fully sealed box, it does not isolate the filter from engine bay heat quite as completely as the 63 Series AirCharger. In practice the difference is modest, but if your absolute priority is the lowest intake temps, the enclosed kits have the edge. The oiled filter also needs the standard clean-and-re-oil maintenance every so often. For sound and looks with trustworthy filtration, the 77 Series is a strong pick.
- Mandrel-bent aluminum tube with a dressed-up finish
- Heat shield helps separate the filter from engine heat
- Washable oiled cotton-gauze filter rated for high mileage
Pros: Deep, pronounced HEMI intake growl; Aluminum tube looks great in the engine bay; Proven K&N filtration with long reusable life
Cons: Heat shield seals less than a fully enclosed box; Oiled filter requires periodic cleaning and re-oiling
Frequently Asked Questions
Will a cold air intake add horsepower to my RAM 1500?
Yes, but keep expectations realistic. On a 5.7L HEMI a quality cold air intake typically frees up a modest horsepower and torque gain on its own, usually in the single-digit range at the wheels, with the biggest improvement felt as sharper throttle response rather than a dramatic dyno jump. The real gains come when the intake is paired with other modifications like a tune, headers, or an exhaust, because then the engine can actually use the extra airflow. Sealed-box kits from K&N, S&B, aFe, and Airaid tend to show the most consistent results because they keep intake air temperatures low.
Does a cold air intake make the RAM 1500 louder?
It does, and for many RAM owners that is the whole point. Replacing the muffled factory airbox with a high-flow filter lets you hear the HEMI breathe, producing a deeper growl under acceleration. Open-element kits like the K&N 77 Series, the aFe Magnum FORCE, and the Spectre kit are the loudest, while fully enclosed boxes like the S&B and Airaid MXP are more refined and quieter at a cruise. If you want presence without highway drone, lean toward a sealed box. If you want maximum induction roar, an open-element kit delivers.
Do I need a tune after installing a cold air intake on a RAM 1500?
For most bolt-on cold air intakes on the RAM 1500, no tune is required. These kits are designed to work with the factory mass airflow sensor and the truck’s existing calibration, so you can install one and drive without throwing a check engine light, provided you install it correctly. The one thing to watch is filter oil. If you use an oiled cotton-gauze filter and apply too much oil, residue can coat the MAF sensor and cause running issues. A tune is only necessary when you stack the intake with bigger modifications like a supercharger or a full exhaust and headers package.
How often do I clean a cold air intake filter on my RAM 1500?
It depends on the filter type and your driving conditions. Washable cotton-gauze filters like those from K&N usually go a long time between cleanings, often around every 30,000 to 50,000 miles under normal driving, and they last roughly the life of the vehicle when maintained. Dry synthetic filters such as the S&B dry option or the Airaid SynthaMax clean even more simply with compressed air. If you drive on dusty job sites, gravel roads, or in heavy off-road conditions, inspect the filter more often. The clear lid on the S&B kit makes that inspection especially easy.
Will a cold air intake void my RAM 1500 warranty?
Installing a cold air intake does not automatically void your factory warranty. Under the Magnuson-Moss Warranty Act in the United States, a manufacturer cannot void your entire warranty simply because you added an aftermarket part. They can, however, deny a specific claim if they can prove the intake directly caused the failure. To stay protected, choose a reputable kit, keep your receipts, and consider an emissions-legal intake with a CARB Executive Order number, like the 50-state-legal K&N options, if you live in a state that checks. Proper installation also matters, since a poorly fitted filter that lets in dust is the kind of thing that can lead to a denied claim.
Our Verdict
For most RAM 1500 owners, the K&N 63 Series AirCharger is the intake to buy. Its sealed roto-molded airbox keeps intake temperatures low, the washable filter lasts for years, and the CARB-legal status keeps it usable in emissions states, all while delivering a throttle response gain you can genuinely feel on the HEMI. Our runner up is the S&B Cold Air Intake, which edges ahead on pure filtration thanks to its published high-efficiency testing, clear inspection lid, and a no-oil dry filter option that makes maintenance foolproof. Choose the K&N for the best all-around package, or the S&B if protecting your engine in dusty conditions is your top concern.
