The 3.6L Pentastar V6 in the Chrysler 300 is a solid engine, but the factory airbox is restrictive and tuned for quiet over flow. A proper cold air intake opens up the throttle response, adds a deeper growl on acceleration, and pulls cooler, denser air into the engine. On a naturally aspirated V6 like this you should expect a modest but noticeable seat-of-the-pants improvement rather than a dyno miracle, and the right kit makes the most of every cubic foot of air the motor can swallow.
We looked at the intakes that actually fit the 2011 and newer Chrysler 300 V6 (and its 3.6L cousins in the Charger and Challenger), focusing on real fitment, filter quality, heat shielding, and whether the kit stays legal and reliable for a daily driver. Below are seven options ranked from our top pick down, with honest notes on where each one falls short.

1. K&N 63 Series AirCharger Cold Air Intake (63-1565): Best Overall
The K&N 63 Series AirCharger is the intake we keep coming back to for the Chrysler 300 V6 because it nails the balance most owners actually want. The roto-molded tube replaces the corrugated factory plastic with a smooth bore, the heat shield does a genuinely good job of keeping hot underhood air away from the filter, and the whole kit bolts on with hand tools in under an hour. On the Pentastar you get crisper throttle response and a richer intake note without crossing into drone territory.
The honest weakness here is maintenance. The cotton gauze filter is washable and lasts the life of the vehicle, but you have to clean and re-oil it periodically, and over-oiling can foul the MAF sensor if you are careless. If you want a true install-and-forget part this is not it. For everyone willing to do light upkeep, the 50-state legality and proven fitment make it the safest all-around choice.
- Roto-molded high-density polyethylene intake tube for smooth airflow
- Washable and reusable High-Flow cotton gauze filter
- Includes heat shield to isolate the filter from engine bay heat
Pros: CARB legal and emissions friendly in all 50 states; Reusable filter saves you from buying replacements; Strong factory-style fitment with minimal cutting
Cons: Requires occasional cleaning and re-oiling; Sound gain is moderate rather than aggressive
2. aFe Power Magnum FORCE Stage-2 Pro 5R Intake: Best Airflow
aFe Power builds the Magnum FORCE Stage-2 for owners who care most about raw airflow. The fully enclosed airbox is the standout feature, sealing the filter off from the engine bay so the intake draws cooler air than the open heat-shield designs many competitors use. On the 300 V6 the result is strong top-end pull and a deeper, more purposeful tone when you get into the throttle. The Pro 5R five-layer filter flows hard while still trapping dust well.
The trade-off is that this is an oiled filter system, so the same MAF caution and cleaning cadence apply as with any cotton gauze setup. It also is not carb legal in every state, so California and similar markets need to confirm before buying. If you live somewhere without that restriction and want the most air this engine can use, aFe is the flow champion of this list.
- Fully sealed one-piece airbox for cold air separation
- Five-layer oiled cotton gauze Pro 5R filter media
- Large diameter rotomolded tube for maximum flow
Pros: Sealed box pulls genuinely cooler air than open designs; Excellent flow numbers for a naturally aspirated V6; Premium fit and finish that looks factory-plus
Cons: Oiled filter needs periodic cleaning; Not legal in every emissions jurisdiction
3. Injen SP Series Cold Air Intake (Polished): Best Build Quality
Injen has a reputation for engineering, and the SP Series shows it. The mandrel-bent aluminum tube looks fantastic under the hood, and the dry SuperNano-Web filter is the headline feature for daily drivers because it never needs oil. That means no risk of contaminating the mass airflow sensor, which is a recurring headache with oiled filters on the Pentastar. Injen also tunes these with MR Technology to keep the torque curve smooth rather than just chasing peak numbers.
Where the SP gives a little ground is heat isolation. It uses a heat shield rather than a fully sealed box, so on a hot day sitting in traffic the open element will sip some warmer engine bay air compared to aFe’s enclosed design. For most driving that difference is small, and the combination of build quality and zero-oil maintenance makes Injen one of the easiest intakes to live with long term.
- Mandrel-bent 6061 aluminum intake tube in polished finish
- Dry SuperNano-Web filter needs no oiling
- MR Technology tuning for a smooth torque curve
Pros: Dry filter avoids MAF over-oiling problems; Show-quality polished aluminum tube; Tuned to preserve low-end driveability
Cons: Polished finish needs wiping to stay clean; Open-element design pulls some warm air without a full box
4. Spectre Performance Air Intake Kit (9978): Best Value
Spectre, which is part of the same family as K&N, aims squarely at owners who want the cold air intake look and feel without the premium price positioning of the top brands. The 300 V6 kit comes complete with a powder-coated tube, a washable conical filter, and a heat shield, so you are not hunting for extra parts. On the road it delivers the expected wake-up in throttle response and a noticeably louder intake howl that many owners specifically buy these for.
The honest caveat is fit and finish. Spectre kits generally install fine, but you may need to spend a few extra minutes adjusting clamps and the shield to get everything seated cleanly, and the filter is oiled so it carries the usual cleaning duty. For a budget-conscious build that still uses quality filter media, it punches above its weight.
- Mandrel-bent powder-coated aluminum intake tube
- Washable and reusable conical cotton filter
- Includes hardware and heat shield for a complete install
Pros: Strong performance per dollar in qualitative terms; Reusable filter for long-term savings; Complete kit with everything needed to install
Cons: Fitment can need minor tweaking; Filter is oiled and requires upkeep
5. S&B Filters Cold Air Intake (Cotton Cleanable): Best Sealed Box
S&B made its name in the diesel world where filtration actually matters, and that philosophy carries into its gas intakes. The fully enclosed airbox with a clear lid is the signature feature, letting you visually inspect filter condition without tools while keeping hot engine air sealed out. On the Chrysler 300 V6 the oversized filter gives plenty of surface area, which means strong flow and longer intervals between cleanings than a small conical element.
The downside is the physical footprint. The boxed design takes up more room than an open cone on a heat shield, and depending on your hands and accessories the install can feel a little tight around the housing. It also sits in the upper pricing tier of this group. If clean, cool, well-filtered air is your priority over saving a few minutes during install, S&B is hard to beat.
- Fully enclosed airbox with a clear inspection lid
- Oversized cotton cleanable filter for high dust capacity
- Dyno-evaluated airflow with reduced filtration loss
Pros: Sealed box keeps intake air cool and clean; Clear lid lets you check the filter at a glance; Large filter means longer service intervals
Cons: Bulkier box can be a tight fit for some hands; Premium pricing tier for the segment
6. Volant Cold Air Intake with PowerCore Filter: Best Dry Filter Box
Volant combines two features people usually have to choose between: a fully sealed airbox and a dry filter. The Donaldson PowerCore element inside needs no oil, so you get the clean-air benefits of an enclosed system without the MAF contamination risk that oiled filters bring. On the 300 V6 it is a sensible pick for owners who want a performance intake but also want to mostly forget about it between services.
The compromises are sound and filter availability. Because it is a sealed box with dry media, the intake note is more refined and less raucous than an open cotton cone, which disappoints buyers chasing maximum noise. PowerCore replacement filters are also less common on store shelves than standard cotton elements, so plan ahead when it is time to service. For a quiet, low-maintenance, cool-air build it is an excellent fit.
- Fully enclosed cross-link polymer airbox
- Dry Donaldson PowerCore filter media
- No oiling required and long service life
Pros: Dry PowerCore filter eliminates MAF oiling worries; Sealed box for cooler, cleaner intake air; Durable molded housing handles heat well
Cons: Replacement PowerCore filters can be harder to source; Sound increase is more subdued than open cones
7. Airaid Cold Air Dam Intake with SynthaMax Dry Filter: Best Heat Shield Design
Airaid rounds out the list with a smart middle-ground design. Rather than a fully enclosed box, it uses a cold air dam that walls off the filter and channels cooler air up from below, which captures much of the benefit of a sealed system while keeping installation simple. The dry SynthaMax filter is washable and needs no oil, so it sidesteps the MAF concerns that come with traditional cotton gauze media on the Pentastar.
The weakness is that the air dam, while effective, is not a complete seal, so on the hottest days it will not isolate the filter quite as well as the boxed aFe or S&B options. Fitment confirmation also varies across the 300 model years, so verify your exact year before ordering. For owners who want a dry, low-maintenance filter and a tidy install without paying for a full enclosure, Airaid is a smart and dependable choice.
- Cold air dam channels cooler air to the filter
- Dry SynthaMax synthetic filter needs no oil
- Roto-molded tube with smooth internal surface
Pros: Dry filter is washable with no oiling step; Cold air dam improves cool-air capture; Easy bolt-on install with good instructions
Cons: Not a fully sealed box like premium rivals; Limited fitment confirmation on some model years
Frequently Asked Questions
Will a cold air intake actually add horsepower to my Chrysler 300 V6?
Yes, but keep expectations realistic. The 3.6L Pentastar V6 is naturally aspirated, so a cold air intake typically frees up a modest gain rather than a large one. What you will feel most clearly is sharper throttle response, a stronger pull in the upper rev range, and a deeper intake sound. The biggest power numbers from any intake come when it is paired with a tune and supporting modifications. On its own, treat the intake as a refinement that lets the engine breathe more freely, not as a bolt-on power miracle.
Are these cold air intakes legal in California and other emissions states?
It depends on the specific kit. The K&N 63 Series is CARB legal in all 50 states, which makes it the safe choice if you live in California or another state with strict emissions checks. Many other intakes on this list, including some aFe and Injen configurations, may carry an off-road or non-CARB status in certain applications. Always check the manufacturer listing for a CARB EO number that matches your exact year and engine before you buy, because a non-compliant intake can cause you to fail a smog inspection.
Should I choose an oiled filter or a dry filter for my 300?
Both work well, and the right pick comes down to maintenance preference. Oiled cotton gauze filters, like those on the K&N, aFe, and Spectre kits, flow extremely well but must be cleaned and re-oiled periodically, and over-oiling can foul the mass airflow sensor if you are not careful. Dry filters, like the Injen SuperNano-Web, Volant PowerCore, and Airaid SynthaMax, simply wash with water and need no oil, which removes the MAF risk entirely. If you want the lowest fuss, go dry. If you want the absolute most airflow, oiled media has a slight edge.
How hard is it to install a cold air intake on a Chrysler 300 V6?
For most owners it is a straightforward weekend job that takes roughly thirty to sixty minutes with basic hand tools. You remove the factory airbox and intake tube, then bolt in the new tube, filter, and heat shield using the supplied hardware. The trickiest parts are usually routing any breather hoses and getting the clamps fully sealed so there are no air leaks. Kits with sealed boxes like S&B and Volant can be slightly tighter to fit, while open-element designs go in faster. No tuning is required for the intake itself on this engine.
Do I need a tune after installing a cold air intake?
Not strictly. The Chrysler 300 V6 will adapt to a quality intake on its own because the factory computer adjusts fueling based on the mass airflow sensor reading. That said, a tune lets you unlock more of the intake’s potential by optimizing the air and fuel tables for the increased airflow, and it can smooth out any minor drivability quirks. If your only goal is better throttle feel and sound, run the intake as is. If you are building toward more performance, plan a tune as the next step to get the full benefit.
Our Verdict
For most Chrysler 300 V6 owners, the K&N 63 Series AirCharger is our top pick because it delivers proven fitment, a reusable filter, a genuine heat shield, and the added security of being legal in all 50 states. If raw airflow is your priority and emissions rules in your area allow it, the aFe Power Magnum FORCE Stage-2 is the runner up, with its fully sealed airbox pulling the coolest air of the group. Choose the K&N for the safest all-around upgrade, and the aFe when you want to squeeze out every bit of breathing room the Pentastar can use.
