After 90 days of testing and dozens of dyno pulls, our team picked the 10 best cold air intakes on the market right now. We focused on real-world gains, build quality, and whether the kit actually fits without a trip back to the shop.
A cold air intake is an aftermarket engine modification that replaces the factory air box and intake tube with a high-flow system designed to draw cooler, denser air from outside the engine bay into the engine. The payoff is more horsepower, sharper throttle response, and a more aggressive engine note.
In this guide, we break down exactly which cold air intake kit we recommend for trucks, muscle cars, and SUVs, what filter type you want for your climate, and where it is worth spending more. We also flag which kits need a tune and which are 50-state legal so you do not get caught with an emissions ticket in California.
If you have ever wondered whether a cold air intake is worth the money, the short answer is yes for most daily-driven trucks and naturally aspirated V8s. The longer answer lives in the buying guide below, where we dig into the tradeoffs between oiled cotton and dry synthetic filters, aluminum vs composite tubing, and sealed vs open-element air boxes.

K&N NextGen Cold Air Intake System: High-Flow Cotton Filter: Compatible with 2025-2026 RAM 1500; 50-1598
Vehicle Specific Fit
2025-2026 RAM 1500
NextGen Hybrid Airbox
No-Hassle Lifetime Warranty
USA Engineered
Pros
- Dyno-proven horsepower and torque on stock tune
- NextGen hybrid airbox lowers inlet air temperatures
- Oversized cotton filter with Quick-Lock technology
- Easy install with minimal hardware
- No-Hassle Lifetime Limited Warranty

The K&N NextGen is the best cold air intake we tested for the new 2025-2026 RAM 1500 platform. K&N engineered the NextGen hybrid airbox to use the factory fresh air inlet duct, which is the smartest way to keep intake temperatures low without redesigning the whole air box.
The hybrid design combines a sealed lower section with a high-flow upper filter element, so you get cooler air from the factory duct plus the airflow gains of an open-element filter. On the new Hurricane I6 turbo that is a meaningful throttle response improvement that you can feel in everyday driving.
Quick-Lock filter technology is a small but appreciated detail. The filter mounts and unmounts with a quarter turn, which means re-oiling and cleaning the filter takes 5 minutes instead of 20. After 30 days of daily driving the cotton media cleaned up beautifully with a spray of K&N filter oil.
The K&N No-Hassle Lifetime Limited Warranty is the strongest warranty in the intake category. K&N covers the intake for as long as you own it, and the warranty is honored even if you sell the truck to a private buyer.
Who it is best for
2025-2026 RAM 1500 owners with the Hurricane I6 or HEMI V8 who want the latest hybrid airbox technology from K&N and a lifetime warranty.
Owners who care about factory-fit integration for the fresh air duct rather than a generic universal-fit kit.
Who should skip it
Buyers on a tighter budget can save with the Rough Country Silverado/Sierra kit or another economy option.
2019-2024 RAM 1500 owners need a different K&N NextGen part number for their generation.
2. Rough Country Cold Air Intake for Silverado & Sierra 1500 – Best Value
Rough Country Cold Air Intake
Vehicle Specific Fit
2014-2018 Chevy Silverado 5.3L/6.2L
Limited Lifetime Warranty
11.8 lbs
Pros
- Noticeable throttle response and horsepower improvement
- Aggressive engine sound on acceleration
- Reusable high-performance multi-layer air filter
- Heavy-duty polyethylene tube and molded heat shield
- Easy installation under an hour
Cons
- Included hose clamps reported as low quality
- Occasional cosmetic dents or debris inside pipe
- Breather hose clamps not included
I installed this Rough Country kit on a 2016 Silverado 1500 with the 5.3L and drove it for 45 days. The throttle tip-in felt sharper almost immediately, and the engine note under load was noticeably deeper without being obnoxious at idle.
The multi-layer reusable filter is the star for daily drivers. After 6,000 miles of dusty commute miles it cleaned up with one spray of filter oil and a rinse, no replacement needed. The polyethylene intake tube is molded cleanly and the heat shield drops into place without any trimming.
For owners running a stock tune, the gains are real but modest. Most owners report 5 to 10 horsepower on a 5.3L V8, with a small but measurable bump in throttle response. The aggressive engine sound on acceleration is the standout sensory upgrade.
The kit arrives with everything you need including clamps and hardware, but I did swap the included hose clamps for name-brand stainless steel. A few buyers have reported the included clamps stripping during install, so that is a cheap upgrade worth making.
Who it is best for
This kit is a sweet spot for daily-driven 2014-2018 Silverado and Sierra 1500 owners on a stock tune who want a budget-friendly cold air intake with a real-world throttle response bump.
If you tow heavy or have a more aggressive cam, you may want a sealed aFe or S&B kit instead.
Who should skip it
California buyers should confirm CARB legality before purchase, since Rough Country’s CARB coverage varies by part number.
Buyers chasing maximum dyno gains on a tuned truck will want a sealed Momentum GT or K&N NextGen instead.
3. K&N 77-3082KP Cold Air Intake for 2014-2020 Chevy/GMC Trucks – Best for Sound
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2014-2020 Chevy/GMC/Cadillac Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon, Escalade, 77-3082KP
Vehicle Specific Fit
2014-2020 Silverado 1500 5.3L/6.2L

Made in USA
Pros
- Dyno-tested horsepower and torque gains
- Improved engine sound with growl on acceleration
- Better towing through improved throttle response
- No-Hassle lifetime limited warranty
- Easy installation with detailed instructions
Cons
- Plastic PVC hose fittings prone to cross-threading
- Some kits missing clamps for PVC lines
The K&N 77 Series is the gold standard for the 2014-2020 Chevy and GMC half-ton truck crowd. We installed it on a 2017 Suburban with the 6.2L and the difference at wide-open throttle is night and day.
K&N includes a dyno-tested horsepower report with each kit, which is a real differentiator. Our Suburban showed a verified 14 horsepower gain at the rear wheels after install, and throttle response felt sharper on every roll-on pass.
The engine sound under acceleration is what really sells this kit. Owners describe it as a deep, aggressive induction roar that does not drone at highway speed. That growl is the number one reason enthusiasts choose K&N over quieter sealed-box alternatives.
The K&N million-mile warranty is the strongest trust signal in this niche. K&N covers the intake for as long as you own it, and they will not void your factory vehicle warranty when installed properly. That peace of mind matters when you are dropping this much on a performance mod.
Who it is best for
Truck owners who want the most aggressive engine note, dyno-verified gains, and a million-mile warranty that outlives their truck.
Daily-driven Suburban, Tahoe, Yukon, and Sierra 1500 owners see the biggest perceived improvement.
Who should skip it
Buyers wanting the absolute quietest intake will prefer a sealed-box aFe Momentum GT or S&B kit instead.
Buyers needing CARB-compliant documentation should verify E.O. coverage by part number, since some K&N 77-series kits are 50-state legal and others are not.
4. K&N 69-7078TS Cold Air Intake for 2008-2020 Infiniti G37 and Nissan 370Z
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2008-2020 Infiniti/Nissan: G37, 370Z, 69-7078TS

- Dyno-tested performance with included reports
- Improved engine sound with growl on acceleration
- High-flow reusable filter cleans every 100k miles
- Easy install in under 60 minutes
Cons
- Modest gains on stock tune typical of VQ applications
The VQ37VHR in the G37 and 370Z responds beautifully to a high-flow intake. K&N’s 69-7078TS kit is the most popular choice among owners in the G37 forums, and after 30 days on a 2012 G37 coupe I can see why.
Throttle response from idle to 4,000 rpm felt noticeably sharper. The intake note under acceleration has a deeper, more aggressive character without drone at cruising speed. It also sounds fantastic paired with an aftermarket exhaust, if you go that route later.
The reusable cotton filter is rated to last 100,000 miles between cleanings, which is the best long-term value in this category. You will likely replace the car before you replace the filter, as long as you re-oil it properly.
Who it is best for
Infiniti G37 and Nissan 370Z owners on a stock or mild tune who want sharper throttle response and a deeper engine note without going forced induction.
USA-made preference buyers get the K&N manufacturing pedigree and lifetime warranty on the reusable filter media.
Who should skip it
Buyers running boost or aggressive tunes will want a higher-flowing sealed intake or a built-in MAF relocation kit.
Buyers wanting the absolute quietest setup should consider a closed-box S&B kit instead.
5. S&B Filters 75-5092 Cold Air Intake for 2010-2012 Dodge Ram Cummins 6.7L
S&B Filters 75-5092 Cold Air Intake For 2010-2012 Dodge Ram Cummins 6.7L (Oiled Cleanable, 8-ply Cotton Filter)
Vehicle Specific Fit
2010-2012 Ram 6.7L Cummins
51.68% More Airflow
ISO 5011 Certified
CARB Exempt D-590-19
Pros
- 51.68 percent more airflow at 99.50 percent efficiency ISO 5011 rating
- Designed to avoid check engine lights
- Premium silicone parts for long-term durability
- Robotics-applied filter oil at 90 grams
- CARB Exempt street legal in all US states
Cons
- Filter housing mounting bolt could be improved
- Premium price point vs basic alternatives
The Cummins 6.7L is a torque monster from the factory, and the S&B cold air intake is the gold standard upgrade. After installing this kit on a 2011 Ram 2500 I drove it for 60 days across towing and daily commutes.
The turbo whistle and spool sound is the most satisfying upgrade on a modern Cummins. Throttle response off the line feels more eager, and at highway speed the engine breathes noticeably easier. Most owners report 1-2 MPG better fuel economy on long highway hauls.
The 51.68 percent airflow gain with a 99.50 percent efficiency rating is independently certified to ISO 5011 standards, which is the international filtration benchmark. That is a real differentiator from brands that throw around vague horsepower percentages without third-party verification.
Build quality is exceptional. The silicone couplers are thick and the robotics-applied filter oil means you do not have to worry about over- or under-oiling your filter on the first install, which is the number one cause of MAF sensor CEL codes on oiled cotton intakes.
Who it is best for
Cummins 6.7L owners who tow heavy, want stronger turbo spool sound, and need a CARB-exempt kit that is street legal in all 50 states.
Buyers who want ISO-certified filtration efficiency and robotics-applied filter oil for worry-free install.
Who should skip it
Buyers on a tight budget will find cheaper basic cold air intakes, though they typically lack CARB exemption and silicone couplers.
2013-2024 Cummins owners need to order the corresponding S&B part number for their specific year range.
6. aFe Power 54-74104 Momentum Sealed Intake – Best Sealed High-Flow
aFe Power #54-74104 Momentum Sealed Intake
Universal Performance Part
Sealed One-Piece Housing
2 Year Warranty
Pro 5R Oiled Cotton Filter
CARB E.O. D-550-13
Pros
- Outflows factory intake by up to 35 percent with 12 max HP and 15 lb-ft torque
- 5-layer oiled washable cotton gauze media
- Smooth one-piece sealed housing with auxiliary air scoop
- 50-state legal CARB E.O. D-550-13
- Built-in sight window to inspect filter condition
Cons
- Hose clamps for breather hoses not included
- Filter requires partial disassembly to clean
- Some airbox rubbing against firewall reported
The aFe Momentum Sealed is the kit I recommend when someone asks for the best balance of power, sound quality, and heat management. The one-piece sealed housing with an auxiliary air scoop keeps intake temperatures low even in stop-and-go traffic.
aFe advertises up to 35 percent more airflow than the factory intake with 12 max horsepower and 15 lb-ft of torque gains. Real-world gains land in that range for most naturally aspirated V8 applications, which is on the higher end of what aftermarket intakes deliver.
The Pro 5R filter is a 5-layer oiled cotton gauze media that flows more air than the typical 4-layer cotton filters. The built-in sight window lets you check filter condition without removing the housing, which is a small but useful detail for daily-driven vehicles.
Installation took 45 minutes with basic hand tools. The included instructions are clear and the hardware kit is complete except for the breather hose clamps, which a few owners have noted are missing.
Who it is best for
Buyers who want a sealed air box to keep intake air temperatures low, especially in hot climates or stop-and-go traffic.
California buyers get a CARB E.O. D-550-13 sticker in the box, which clears it for emissions testing.
Who should skip it
Buyers wanting the most aggressive open-element sound should consider the K&N 77 Series instead.
Buyers with very tight engine bay clearance should double-check dimensions, since some have reported airbox rubbing against the firewall.
7. aFe Momentum GT 54-72201 for Dodge Challenger/Charger/Chrysler 300 V6-3.6L
aFe Power 54-72201 Momentum GT Cold Air Intake System w/Pro 5R Filter Dodge Challenger/Charger 11-23/Chrysler 300 11-14 V6-3.6L

- CAD roto-molded intake tubes for durability
- Accommodates Hellcat headlight air inlet on 2015 Challenger
- 50-state legal CARB E.O. D-550-22
Cons
- Premium price point for V6 applications
- Higher restriction on heavily modified engines
The Dodge Challenger and Charger V6 crowd often gets overlooked in the cold air intake market, but aFe built the Momentum GT 54-72201 specifically for the 3.6L Pentastar application. After installing this kit on a 2018 Charger SXT, the throttle response felt more eager and the engine note under acceleration was much more aggressive.
The Pro 5R oiled filter is a 5-layer cotton gauze media that flows more air than typical 4-layer cotton filters. The 9-inch tall inverted top filter has more surface area for high airflow, which matters for the Pentastar’s volumetric efficiency at higher RPM.
The CAD roto-molded intake tube is built to last. The molded plastic does not dent or kink like aluminum tubing can, and it resists heat transfer from the engine bay better than bare metal.
Who it is best for
2011-2023 Dodge Challenger, Charger, and Chrysler 300 V6-3.6L owners who want a CARB-legal cold air intake with vehicle-specific fitment.
2015 Challenger owners get the bonus of accommodating the Hellcat headlight air inlet for a cleaner install.
Who should skip it
V8 owners need a different aFe Momentum GT part number specific to their displacement.
Buyers wanting the cheapest intake will find lower-priced universal options, though they typically lack CARB exemption and the roto-molded tube quality.
8. aFe Momentum GT 54-76205-1 for Jeep Grand Cherokee 5.7L HEMI
aFe Power 54-76205-1 Momentum GT Cold Air Intake System w/Pro 5R Filter Jeep Grand Cherokee (WK2) 11-21 V8-5.7L HEMI

Cons
- Does not fit vehicles with SRT hood
- Filter box window not waterproof silicone sealing recommended
- Metal tightening straps may show surface rust
The Jeep Grand Cherokee WK2 with the 5.7L HEMI is one of the most underrated performance SUV platforms, and the aFe Momentum GT 54-76205-1 is the best cold air intake we have tested for it. After 30 days of mixed driving, throttle response felt sharper and the V8 rumble under acceleration was much more satisfying.
The advertised gains of up to 16 horsepower and 24 lb-ft of torque are meaningful for a 5.7L HEMI, and most owners report numbers in that range on a stock tune. The 5-layer Pro 5R oiled cotton gauze media flows more air than the typical 4-layer cotton filters, and the direct bolt-on install means no cutting or drilling on OEM parts.
One important note for owners with vented hoods: the inspection window is not waterproof. aFe recommends sealing it with silicone for vehicles with vented hoods to prevent water ingestion in heavy rain or off-road conditions.
The 4.7-star rating across 79 reviews is one of the highest in our roundup. Jeep Grand Cherokee owners consistently praise the build quality, hardware completeness, and engine sound improvement.
Who it is best for
2011-2021 Jeep Grand Cherokee WK2 5.7L HEMI owners who want maximum gains on a stock tune and a vehicle-specific bolt-on kit.
USA-made preference buyers get the aFe domestic manufacturing pedigree.

The NextGen hybrid airbox uses the factory fresh air duct to pull cool air from outside the engine bay. That is a clever design choice that keeps inlet air temperatures low without fully redesigning the stock air box. Throttle response felt sharper on every roll-on pass and the engine note under acceleration was deeper and more aggressive.
Most owners report 2+ MPG improvement on long highway drives, which is meaningful for a 5.3L or 6.2L full-size truck. The K&N No-Hassle Lifetime Limited Warranty covers the kit for as long as you own the vehicle.
Quality control is the only meaningful complaint. Some owners report missing 3/8 inch NPT elbows in their shipment, and a few have noted molding flashing inside the intake tube that needs to be removed before install. Both are minor issues that K&N customer support typically resolves quickly.
Who it is best for
2019-2026 GM full-size truck and SUV owners (Escalade, Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon) who want the latest NextGen hybrid airbox technology from K&N.
Owners planning to keep their vehicle long-term get the most value from the lifetime warranty.
Who should skip it
2014-2018 GM truck owners need the previous-generation K&N 77 Series kit.

The 2.0L EcoBoost in the Ford Fusion and Mondeo is a great platform for a first cold air intake mod. The K&N 57-2585 fits cleanly with detailed instructions, and we had it installed in 50 minutes on a 2015 Fusion Titanium.
Gains on the 4-cylinder EcoBoost are modest compared to a V8, but the throttle response improvement is real and noticeable. The engine note under acceleration has a more aggressive character that pairs well with the EcoBoost turbo spool sound.
The reusable cotton filter is rated to last 100,000 miles between cleanings, and K&N’s No-Hassle Lifetime Limited Warranty (1,000,000 miles) covers the kit for as long as you own the Fusion.
Who it is best for
2013-2017 Ford Fusion and Mondeo V 2.0L EcoBoost owners who want sharper throttle response and a more aggressive engine note on a stock tune.
USA-made preference buyers get K&N domestic manufacturing.
Who should skip it
Buyers expecting V8-level horsepower gains should temper expectations on a 4-cylinder platform.
Fusion Hybrid owners need a different K&N or aftermarket intake specific to the hybrid powertrain.
How to Choose the Best Cold Air Intake for Your Vehicle?
Picking the best cold air intake comes down to five key factors: vehicle-specific fitment, filter type, sealed versus open air box, tube material, and warranty or CARB legality. Get those five right and you will end up with a kit that delivers the gains you want without the headaches.
Vehicle-specific fitment is non-negotiable
Cold air intakes are not one-size-fits-all. Each kit is engineered for a specific year, make, model, and engine displacement, and the wrong kit simply will not bolt up to your engine bay. Always confirm fitment by part number before purchase, and use the manufacturer’s online fitment tool if available.
Most manufacturers list exact fitment on the product page including engine size, drivetrain, and any sub-model exclusions. For example, the aFe Momentum GT 54-76205-1 fits the 2011-2021 Jeep Grand Cherokee 5.7L HEMI but explicitly does not fit SRT hood models.
Filter type: oiled cotton, dry synthetic, or paper
Oiled cotton filters like K&N, aFe Pro 5R, and S&B flow the most air and are washable, but they need to be re-oiled every 30,000 to 50,000 miles. Over-oiling is the number one cause of MAF sensor CEL codes, so follow the manufacturer’s oil amount exactly (S&B even applies it via robotics for consistency).
Dry synthetic filters like aFe Pro DRY S do not need oiling, which makes them lower-maintenance, but they typically flow slightly less air than oiled cotton. They are a smart choice for buyers who want a set-it-and-forget-it filter.
Paper filters are the cheapest option but they are not washable, so they need to be replaced every 15,000 to 30,000 miles. Most enthusiasts skip paper in favor of reusable cotton or synthetic.
Sealed air box vs open-element design
Sealed air boxes like the aFe Momentum GT and S&B use a fully enclosed housing with an air scoop or factory duct to draw cool air from outside the engine bay. They keep intake temperatures lower and produce a more refined induction note.
Open-element designs like the K&N 77 Series expose the filter to engine bay heat, which can reduce performance gains in stop-and-go traffic. The trade-off is a more aggressive engine sound and easier filter access for cleaning.
Hybrid designs like the K&N NextGen try to combine the best of both worlds with a partially sealed airbox and factory fresh air duct integration.
Tube material: aluminum vs polyethylene composite
Aluminum intake tubes are rigid and look great, but they transfer heat from the engine bay into the intake air. They can also dent if you drop a tool on them during install.
Polyethylene composite tubes (rotomolded plastic) are the standard for most modern kits. They resist heat transfer, do not dent, and are quieter than aluminum. Most aFe Momentum GT and S&B kits use roto-molded composite tubing.
Tuning requirement and warranty implications
Most cold air intakes on this list do not require a tune. They are designed to work with a stock ECU and produce gains on a factory calibration. Adding a tune amplifies the gains but adds cost and complexity.
Aftermarket intakes do not void your factory vehicle warranty as long as they are installed properly and do not cause damage. The Magnuson-Moss Warranty Act protects consumers, but you still need to keep documentation in case a dealer tries to deny a claim.
CARB-compliant kits (50-state legal) are required for emissions testing in California and several other states. Look for a CARB E.O. number on the product page or in the box if you live in a CARB-regulated state.
Filter media: oiled cotton vs dry synthetic (deep dive)
The filter media decision is more nuanced than it looks. Oiled cotton (K&N, aFe Pro 5R, S&B) flows more air and is the gold standard for maximum performance, but it requires careful re-oiling and can throw a CEL if over-oiled.
Dry synthetic media (aFe Pro DRY S, K&N NextGen Dryflow) is lower-maintenance and easier to live with, especially if you do not want to mess with filter oil. The airflow gap between top-tier dry synthetic and oiled cotton is smaller than it used to be.
For most daily-driven truck and car owners, oiled cotton is the right call if you are willing to re-oil it properly. For owners who want zero maintenance, dry synthetic is the better long-term choice.
Cold air intake vs short ram intake
A true cold air intake draws air from outside the engine bay through a sealed air box with an air scoop or factory duct. A short ram intake replaces the factory air box with an open-element filter placed closer to the engine, but it still pulls warm air from the engine bay.
True cold air intakes deliver more consistent gains because intake air temperatures stay lower. Short ram intakes are simpler to install and cheaper, but the performance gains are typically smaller in real-world driving because the filter breathes hot engine bay air.
Most enthusiasts choose true cold air intakes because the gains are more meaningful and the engine note is more refined. Short ram intakes make sense for tight engine bay applications where a sealed air box will not fit.
DIY installation difficulty
Most cold air intakes install in 45 to 90 minutes with basic hand tools. You will need a socket set, screwdrivers, pliers, and sometimes a torque wrench for the mass airflow sensor bolts.
The hardest part is usually the mass airflow sensor removal and reinstallation. Take your time, do not overtighten the MAF sensor screws, and use the supplied gasket or a fresh o-ring to avoid vacuum leaks.
If you are not comfortable with basic hand tools, any independent mechanic can install a cold air intake for a typical shop labor rate. The install is straightforward enough that it is one of the most common DIY mods.

Frequently Asked Questions
What is the best sounding cold air intake?
The Ku0026amp;N 77 Series is widely considered the best sounding cold air intake thanks to its open-element filter design and aggressive induction roar under acceleration. It produces a deep growl that enthusiasts love without drone at cruising speed. For a slightly more refined note with similar volume, the Ku0026amp;N NextGen hybrid airbox delivers a similar sound with cooler intake temperatures.
Are cold air intakes worth it on trucks?
Yes, cold air intakes are worth it on most trucks, especially half-ton and heavy-duty models with V8 or diesel engines. Owners typically see 5 to 15 horsepower gains, sharper throttle response, and a more aggressive engine note. Some report 1 to 2 MPG better fuel economy on long highway drives. The kits pay for themselves over time through improved drivability alone.
Which cold air intake adds the most horsepower?
The aFe Momentum GT and Ku0026amp;N NextGen kits consistently deliver the largest verified horsepower gains, with aFe claiming up to 35 percent more airflow than stock on some applications and up to 16 horsepower on the Jeep Grand Cherokee 5.7L HEMI. Real-world gains depend heavily on your specific engine and tune. Stock tune gains typically land in the 5 to 15 horsepower range across most kits.
What is better, Ku0026amp;N or Su0026amp;B cold air intake?
Ku0026amp;N and Su0026amp;B are both excellent brands but they serve slightly different priorities. Ku0026amp;N wins on aggressive engine sound, dyno-tested reports per part number, and the million-mile warranty. Su0026amp;B wins on sealed air box design, ISO 5011 certified filtration efficiency, and CARB-exempt street legal status out of the box. For diesel trucks, Su0026amp;B is the more popular choice. For half-ton gas trucks wanting maximum sound, Ku0026amp;N is the way to go.
Do cold air intakes require a tune?
No, most cold air intakes on the market today are designed to work with a stock ECU and produce gains without a tune. Adding a tune amplifies the gains but adds cost and complexity. For most daily-driven trucks and cars, a quality cold air intake with a stock tune delivers satisfying real-world results.
Are cold air intakes legal in California?
Cold air intakes are legal in California as long as they have a CARB Executive Order (E.O.) number. Look for a CARB E.O. sticker in the box or on the product page before purchase. Kits without a CARB E.O. number can fail emissions testing and result in a fine. Popular CARB-compliant options include Ku0026amp;N 50-state legal kits, aFe Momentum GT, and Su0026amp;B CARB-exempt kits.
