An air intake is among the most popular first mods for the Ram 1500 because it is bolt-on simple and you can actually hear and feel the difference the moment you stomp the throttle. The factory airbox on the 5.7L HEMI and the 3.6L Pentastar is built for quiet, restrictive airflow, so swapping in a free-flowing intake wakes up throttle response, deepens the induction growl, and on many trucks frees up a handful of horsepower and torque up top. The catch is that the market is flooded with cheap parts that sound loud but flow dirty air, so picking the right kit matters more than the badge on the box.
We focused on intakes that physically fit the most common Ram 1500 platforms, the DT body 2019 and newer and the classic 1500 from 2009 to 2018, and we weighted three things above all else: filtration quality, real-world throttle response, and how honest the heat shielding is at keeping engine bay heat away from the filter. Below are the seven kits that earned their spot, ranked best first, with an honest look at where each one falls short.

1. K&N 63 Series AirCharger Cold Air Intake (Ram 1500 5.7L HEMI): Best Overall
The K&N 63 Series AirCharger is the kit we kept coming back to because it nails the part most intakes get wrong, which is sealing the filter away from hot engine bay air. The roto-molded tube and the enclosed shield mate cleanly to the factory hood seal, so the filter is actually breathing cooler air from the front of the bay instead of recirculated heat. On the 5.7L HEMI that translates to crisper throttle tip-in and a noticeably fuller mid-range pull, and the induction note deepens without turning into the droning racket some kits produce. Installation is genuinely bolt-on with hand tools, and the 50-state legal status means you are not gambling at the emissions station.
The honest weakness here is the maintenance routine. The cotton-gauze filter is washable and reusable, which is great for long-term value, but it has to be re-oiled after cleaning, and over-oiling can contaminate the mass airflow sensor and throw a code. If you are the type who would rather never touch the filter again, that upkeep can feel like a chore. The sound is also more grown-up than rowdy, so buyers chasing the loudest possible whoosh may walk away slightly underwhelmed even though the performance is the best of the bunch.
- Fully enclosed heat shield seals against the factory hood line to pull cooler air
- Reusable cotton-gauze filter cleans and re-oils instead of needing replacement
- Direct bolt-on fit with no cutting on the 5.7L HEMI Ram 1500
Pros: Best balance of airflow, filtration, and clean installation in the group; Carb-legal in all 50 states so it passes emissions checks; Filter lasts the life of the truck with periodic cleaning
Cons: Sound is deep and refined rather than aggressively loud; Re-oiling the filter takes a little care to avoid over-oiling the MAF sensor
2. S&B Cold Air Intake (Ram 1500 5.7L HEMI, Dry Extendable Filter): Best Filtration
If your Ram 1500 actually works for a living or sees gravel, ranch roads, and dust, the S&B is the intake we trust most to protect the engine. Its claim to fame is a fully sealed airbox paired with a large, high-efficiency dry filter that S&B rates near 99.9 percent, which is exactly what you want when fine grit is the enemy. Because the filter is dry, there is no oil to migrate onto the mass airflow sensor, so you avoid a very common causes of intake-related check engine lights. The sealed box also does an excellent job keeping intake air temperatures down, and on the HEMI you get a cleaner, more consistent throttle response across the rev range.
The trade-off is character. This kit is tuned for protection and clean airflow rather than theater, so the induction sound is subtler than the open-filter crowd will like. The dry filter also asks for more frequent cleaning if you genuinely live in dusty conditions, since dry media loads up faster than oiled media in those environments. None of that hurts performance, but buyers expecting a dramatic new soundtrack should look elsewhere in this list.
- Sealed one-piece airbox blocks hot air better than open shield designs
- Dry filter rated near 99.9 percent efficiency for dusty and off-road use
- Large filter surface area keeps airflow high between cleanings
Pros: Outstanding dust filtration for trucks that see dirt roads and trails; Dry filter cleans with no oil so there is no MAF contamination risk; Tight sealed box keeps intake air temperatures low
Cons: Quieter induction sound than open-element kits; Dry filter needs more frequent cleaning in heavy dust
3. aFe Power Magnum FORCE Stage-2 Cold Air Intake (Ram 1500 5.7L HEMI): Best for Power Gains
The aFe Magnum FORCE Stage-2 is the kit to grab if peak power is your priority. aFe engineers a large-diameter rotomolded tube that straightens and smooths the airflow path, and on the 5.7L HEMI that shows up as a stronger top-end pull where the restrictive factory box runs out of breath. You also get to choose your filter philosophy: the oiled Pro 5R chases maximum flow, while the Pro DRY S skips oil entirely for fuss-free maintenance. Either way the enclosed heat shield with its hood seal keeps the filter fed with cooler air, so the gains are real rather than just dyno-queen numbers that evaporate in traffic.
Where it loses a little ground is installation. That bigger tube has to route around accessories, and the fit, while correct, takes more patience and fiddling than the cleaner K&N or simpler Spectre kits. If you opt for the oiled Pro 5R filter you also inherit the standard re-oiling discipline, with the same MAF-contamination caution that comes with any oiled element. For a buyer focused squarely on output, those are easy compromises, but it is not the most beginner-friendly box in this roundup.
- Big diameter intake tube smooths airflow for stronger top-end pull
- Choice of oiled Pro 5R or oil-free Pro DRY S filter media
- Enclosed heat shield with hood seal isolates the filter from engine heat
Pros: Among the strongest dyno-proven gains for the HEMI in this group; Filter media choice lets you prioritize flow or zero-oil convenience; Aggressive yet refined induction tone
Cons: Larger tube routing makes the install slightly fussier; Oiled Pro 5R option carries the usual re-oiling care requirements
4. Airaid MXP Series Cold Air Intake (Ram 1500 5.7L HEMI): Best Sealed Airbox
Airaid’s MXP series takes the sealed-box approach and finishes it nicely, with a fully enclosed airbox and a clear lid that completely isolates the filter from the hot engine bay. On the HEMI that consistency pays off in steady throttle response and intake temperatures that stay low even after the truck has been sitting at idle in summer heat. The SynthaMax dry filter is the option we would pick, since it cleans without oil and removes the MAF-contamination worry, and the molded one-piece tube with proper clamps makes the whole install look like it came from the factory rather than a parts box.
The downside is the same one that comes with any well-sealed box: it is quiet. Sealing the filter away from the engine bay also seals away a lot of the induction noise, so if you wanted a loud, attention-grabbing intake this is not it. The clear lid is a nice showcase when the filter is fresh, but it also broadcasts every bit of dirt the filter collects, so it can look grimy between cleanings in ways a closed box would hide.
- Enclosed MXP box with a clear lid keeps the filter fully isolated from heat
- SynthaMax dry filter option needs no oil and cleans easily
- Molded intake tube and clamps give a tidy factory-like fit
Pros: Fully sealed box delivers consistent cool intake temps; Clean, well-finished install that looks factory-engineered; Strong throttle response with a controlled sound
Cons: Enclosed design mutes the induction growl; Clear lid shows filter dirt and can look grimy over time
5. Spectre Performance Air Intake Kit (Ram 1500 5.7L HEMI): Best Value
Spectre is the smart pick when you want most of the intake experience without overthinking the purchase. The kit centers on a mandrel-bent aluminum tube that flows far better than the stock corrugated plastic, paired with a washable conical cotton filter that you can clean and reuse for years. On the 5.7L HEMI the result is a satisfying bump in throttle response and a genuinely good induction growl, and the bolt-on heat shield goes in with basic hand tools, making this one of the easiest installs for a first-time modder. For the money it punches well above its weight.
The honest limitation is the heat shielding. Spectre uses a more open shield design rather than a fully enclosed airbox, so under the hood it lets in more radiant engine heat than the sealed K&N, S&B, or Airaid kits, which slightly blunts the cool-air advantage on hot days. The conical filter is also oiled, meaning you inherit the same re-oiling care so you do not contaminate the MAF sensor. Those are reasonable concessions for the value, but it is a step behind the sealed boxes on pure intake-air-temperature performance.
- Mandrel-bent aluminum tube improves flow over the stock plastic box
- Washable, reusable conical cotton filter for long-term use
- Straightforward heat shield install with basic hand tools
Pros: Strong throttle and sound improvement for the value; Reusable filter keeps long-term ownership economical; Beginner-friendly bolt-on installation
Cons: Open-style shield lets in more heat than fully sealed boxes; Filter is oiled so it needs careful re-oiling
6. Volant Cold Air Intake with PowerCore Filter (Ram 1500 5.7L HEMI): Best for Dusty Conditions
Volant earns its place for the buyer who drives where the air is full of dust. The sealed, one-piece airbox does a strong job isolating the filter from engine heat, and the standout is the PowerCore filter media, which packs an enormous amount of dust-holding capacity into a compact element. On a Ram 1500 that spends time on dirt roads or job sites, that capacity means long intervals between maintenance without sacrificing protection, and because the media is oil-free you sidestep the MAF-contamination headache that plagues oiled filters entirely.
The trade-off is in how that filter is serviced. The PowerCore element is built to be replaced once it is fully loaded rather than washed and reused indefinitely, so the long-term consumable story is different from a lifetime cotton filter. And like the other sealed boxes here, Volant prioritizes clean, cool airflow over noise, so the induction sound stays restrained. For a work truck or an overlander that is exactly the right set of priorities, but a buyer chasing volume and a reusable filter will prefer a kit higher on this list.
- Fully enclosed one-piece airbox blocks engine heat effectively
- PowerCore filter option trades cleaning for exceptional dust capacity
- Oil-free filter media avoids MAF sensor contamination
Pros: Excellent dust handling for off-road and rural driving; Sealed box keeps intake temperatures low and stable; No oiling required so maintenance is simple
Cons: PowerCore filter is replaced rather than washed when fully loaded; Quieter sound than open-element designs
7. Injen PF Series Cold Air Intake (Ram 1500 5.7L HEMI): Best Looking Tube
Injen’s PF Series is the pick for owners who care about how the engine bay looks as much as how it performs. The polished, mandrel-bent aluminum tube is genuinely show-quality and gives the Ram 1500 a finished, purposeful look that the plastic stock box cannot match. Performance is no afterthought either, with a real improvement in throttle response and a satisfying induction note on the HEMI, and you can spec it with Injen’s dry SuperNano-Web media if you would rather skip oiling the filter. The kit arrives complete with the heat shield, hardware, and clamps, so everything you need for the install is in the box.
The compromises are mostly cosmetic and thermal. That gorgeous polished tube is a magnet for fingerprints and dust, so keeping it looking sharp means the occasional wipe-down, which the matte-finish kits never ask for. More importantly, the heat shield is less fully sealed than the enclosed boxes from S&B, Airaid, and Volant, so on a punishing hot day it does not isolate the filter from engine heat quite as effectively. It performs well and looks the best of the group, but it sits lower here because pure intake-air-temperature control is not its strongest suit.
- Polished mandrel-bent PF tube adds a clean show-quality look
- Available with dry SuperNano-Web or oiled filter media
- Complete kit includes shield, hardware, and clamps for a full install
Pros: Eye-catching polished finish stands out under the hood; Noticeable throttle response and induction sound improvement; Dry filter option for low-maintenance ownership
Cons: Polished tube shows fingerprints and needs occasional wiping; Heat shield is less sealed than full-box competitors
Frequently Asked Questions
Will a cold air intake actually add horsepower to my Ram 1500?
Yes, but set realistic expectations. On the 5.7L HEMI a quality intake typically frees up a modest handful of horsepower and torque, mostly in the upper rev range where the restrictive factory airbox runs out of breath. The bigger, more noticeable change for most owners is sharper throttle response and a deeper induction sound rather than a dyno-shattering power jump. If you pair the intake with a tune, the gains become more meaningful, but on its own an intake is best thought of as a sound, response, and breathing upgrade with a small power bonus.
Are these air intakes legal and will my truck still pass emissions?
It depends on the specific kit. Some intakes, including the K&N 63 Series, carry a CARB Executive Order number that makes them 50-state legal so they pass emissions inspections everywhere. Others are sold for off-road or race use only and may not be street legal in emissions-strict states like California. Before buying, check the product listing for a CARB EO number if you live somewhere with testing. A legal kit also protects you at resale and avoids the hassle of swapping the stock box back in before an inspection.
Do I need to oil my air intake filter, and what happens if I get it wrong?
Only oiled cotton-gauze filters need oiling, such as the K&N and the oiled-media options from aFe and Spectre. After you clean an oiled filter you must re-oil it, and the most common mistake is using too much oil, which can migrate onto the mass airflow sensor downstream and trigger a rough idle or a check engine light. If you would rather avoid that entirely, choose a dry filter kit like the S&B, the Pro DRY S option from aFe, or the Airaid SynthaMax, which clean with no oil and carry zero MAF-contamination risk.
Is an open filter or a fully sealed airbox better for the Ram 1500?
A fully sealed airbox is the better choice for performance and engine protection because it isolates the filter from hot engine bay air and pulls cooler, denser air, which also keeps intake temperatures consistent. Sealed boxes like the S&B, Airaid MXP, and Volant excel here. The trade-off is sound, since sealing the filter away also quiets the induction growl. Open-shield kits like the Spectre let in more heat but reward you with a louder, more aggressive sound. Decide whether cool-air consistency or volume matters more to you.
Can I install a Ram 1500 air intake myself, and how long does it take?
Yes, almost every intake on this list is a true bolt-on that an average owner can install in the driveway with basic hand tools, usually in under an hour. You remove the factory airbox, set the new heat shield and filter, slide the tube onto the throttle body inlet, and tighten the clamps. The K&N and Spectre kits are among the most beginner-friendly, while the larger-tube aFe takes a bit more patience routing around accessories. Always reconnect any sensors and clamp the tube fully so you do not pull unfiltered air, and double-check everything is snug before your first drive.
Our Verdict
For most Ram 1500 owners the K&N 63 Series AirCharger is the best overall air intake because it delivers the cleanest balance of cooler sealed airflow, sharp throttle response, a refined deep growl, a lifetime washable filter, and 50-state legal confidence on the road. If you drive in heavy dust or want the strongest filtration with zero oiling worry, the S&B Cold Air Intake is the runner up and our top pick for work trucks and off-road use, while buyers chasing peak power should look hard at the aFe Magnum FORCE Stage-2. Whichever you choose, prioritize a sealed box and honest filtration over the loudest sound, and your HEMI will breathe better for the life of the truck.
