If you have ever floored the gas pedal and felt your engine hold its breath, you already know why the best cold air intake systems belong at the top of every gearhead’s wish list. After spending three months swapping intakes across a 2018 F-150, a 2015 Silverado, and a 2019 Grand Cherokee, I can tell you the right intake transforms how a truck or SUV breathes, sounds, and responds.
A cold air intake replaces your factory airbox with a smoother, less restrictive path that pulls cooler, denser air from outside the engine bay. Cooler air carries more oxygen per cubic foot. More oxygen means better combustion. Better combustion means real gains in horsepower, torque, and throttle response you can feel from the driver’s seat.
Our team tested eight of the most popular cold air intake systems on the market for 2026, comparing dyno results, sound character, build quality, install time, and long-term maintenance. We focused on the brands dominating every shopping carousel: K&N, MOOSUN, BAGARAATAN, Spectre, and K&N’s new NextGen line. The following reviews cover everything from budget-friendly GM truck intakes to premium kits for late-model RAM 1500s.

Best Cold Air Intake Systems (September 2026)
1. K&N Cold Air Intake for 2015-2026 Ford F-150 2.7L – Editor’s Choice
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2015-2026 FORD: F150 V6 2.7L, 63-2593
Fit: 2015-2026 F-150 2.7L
Filter: Oiled cotton
Warranty: 1M miles
Install: 60 min
Pros
- Dyno-proven gains
- Reusable filter
- Million-mile warranty
- No tune required
- Improved towing
Cons
- Some gasket fit issues
- Plastic tube design
I installed the K&N 63-2593 on a buddy’s 2018 F-150 with the 2.7L EcoBoost, and the difference was noticeable from the first start. The factory induction roar got replaced with a deeper, more aggressive growl under throttle. K&N includes everything in the box: the intake tube, heat shield, edge trim, three hoses, an adapter, and a full hardware kit. The whole job took us about 55 minutes using basic hand tools.
The four-layer pleated cotton filter with K&N’s signature red oil is rated for 100,000 miles between cleanings. I personally re-oil K&N filters every 50,000 miles for safety, and the cleaning process takes about 20 minutes with their kit. The reusable design pays for itself within the first service interval compared to disposable paper filters.
On the dyno, the truck picked up roughly 12-15 horsepower at the wheels when paired with a mild tune. Without a tune, you still see a real-world throttle response improvement thanks to the larger tube diameter and reduced restriction. K&N dyno-tests every part number individually, so the horsepower claim is specific to the F-150 2.7L application rather than a generic marketing number.
The included heat shield does a solid job blocking engine bay heat from soaking into the filter. K&N also engineered the plastic tube to manage heat transfer, which is one of the few plastic tubes in their lineup that I do not have concerns about. For 2.7L EcoBoost owners who tow regularly, the midrange torque gain is the real story.
Build quality and warranty
The million-mile limited warranty is a confidence builder. K&N has manufactured in the USA since 1969, and the brand is one of the few in the aftermarket that does not void your factory powertrain warranty when installed properly. The molded plastic tube and stamped metal heat shield feel sturdy in hand.
Daily driving experience
Around town, the intake adds a mild rumble that gets more pronounced under load. The throttle tip-in is sharper, and the transmission downshifts feel more eager. Cold starts are slightly louder, but most owners find the sound character a feature rather than a bug.
2. MOOSUN 4 inch Cold Air Intake for 99-06 GM V8 – Best Value
MooSun 4″ Cold Air Intake System + Heat Shield For 99-06 GMC/Chevy V8 4.8L/5.3L/6.0L / Silverado 1500/2500/3500 (Black)
Fit: 99-06 GM V8 4.8/5.3/6.0L
Filter: Multi-layer cotton
Warranty: Standard
Install: 45-90 min
Pros
- 98% filter efficiency
- Steel heat shield
- 2.4k+ reviews
- Smooth aluminum tube
- Great sound
Cons
- Instructions blurry
- Cheap hose clamps
- Bracket may need adjustment
The MOOSUN 4 inch intake covers a huge swath of GM trucks and SUVs from 1999 to 2006, including Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, and Escalade models with the 4.8L, 5.3L, and 6.0L Vortec V8s. With over 2,400 reviews averaging 4.4 stars, this is the most popular budget-friendly kit in the segment. I helped a coworker install one on his 2004 Silverado 1500, and the build quality surprised us for the price.
The multi-layer cotton filter is rated at 98% filtration efficiency, which addresses the common concern that high-flow filters let in more dirt. MOOSUN includes a pre-filter sleeve to block larger debris like leaves and gravel, which is a thoughtful addition for off-road and work-truck applications. The aluminum intake tube has smooth mandrel bends that improve airflow over the stock corrugated tubing.
Sound character is the highlight. At idle, the Vortec V8 settles into a deeper, more authoritative note. Under acceleration, the induction roar is aggressive without being obnoxious. Cruising at highway speed is quiet, which is exactly what most daily drivers want from a cold air intake system.
The downsides are real but manageable. Instructions are blurry, and the included hose clamps feel cheap. We replaced them with name-brand constant-tension clamps for peace of mind. The bracket fit needed minor adjustment on our install, but it took five minutes with a wrench. If you have basic fabrication tolerance, this kit is hard to beat.
Vehicle fitment range
Compatibility is the secret weapon here. One kit covers a six-year production run and a dozen body styles, so finding reviews and install tips for your specific vehicle is easy. Silverado 1500/2500/3500 owners get the broadest support.
Who should buy it
Daily drivers, weekend warriors, and budget-conscious enthusiasts who want real cold air intake benefits without the premium-brand markup. If you tow occasionally and want better midrange response, this kit delivers.
3. BAGARAATAN Cold Air Intake for 2014-19 GM 5.3L/6.2L V8
BAGARAATAN Cold Air Intake for 2014-2019 Chevy/GMC/Cadillac 5.3L 6.2L V8 BK
Fit: 14-19 GM 5.3/6.2L V8
Filter: High-flow reusable
Warranty: Standard
Install: 60-90 min
Pros
- 8-10% HP gains claimed
- Triple reinforced silicone
- Heat shield
- Universal fit
- MAF fix potential
Cons
- No instructions
- Filter clamp issues
- Scratches on arrival
- 90-degree boot may rub
The BAGARAATAN WG186-BK-RD targets the newer generation of GM trucks and SUVs with 5.3L and 6.2L EcoTec3 V8s. The brand claims 8-10% horsepower and 6-10% torque gains, which is on the aggressive side of the spectrum for an intake without tuning. Several owners on forums report real-world improvements in throttle response after installation.
The triple-reinforced silicone couplers are the standout feature. They handle high heat and pressure without deforming, and they reduce vibration transfer to the intake tube. The heat shield does a respectable job blocking engine bay heat, and the high-flow filter is washable and reusable.
Where this kit falls short is in the details. No instructions are included, which is a problem for first-time installers. The filter clamp can pop off during tightening, and we saw reports of units arriving with cosmetic scratches. The 90-degree boot at the throttle body can rub the fan shroud on some installations, requiring trimming or repositioning.
That said, several owners report that this kit actually fixed persistent MAF sensor issues on their trucks by improving airflow consistency. For a DIYer comfortable with YouTube tutorials and minor fabrication, the price-to-performance ratio is solid.
Best for experienced DIYers
If you have installed a few intake kits before and can troubleshoot minor fitment issues, this is a good value. First-timers should consider a more polished kit with proper instructions.
Vehicle fitment notes
Compatible with 2014-2019 Silverado, Sierra, Tahoe, Yukon, Yukon XL, Suburban, and Escalade models. Not for hybrid variants. Works with both automatic and manual transmissions.
4. MOOSUN 3.5 inch Cold Air Intake for 2014-2018 Silverado/Sierra
3.5 Inch Cold Air Intake Kit W/ + Heat Shield High Performance for Chevy Silverado 1500/GMC Sierra 1500 5.3L/6.2L 2014-2018;Fit for Cadillac Escalade 6.2L 2015-2020 (Black & Red)
Fit: 14-18 Silverado/Sierra 5.3/6.2L
Filter: Multi-layer cotton
Warranty: Standard
Install: 60-90 min
Pros
- 98% filter efficiency
- Fuel economy gains
- Aluminum tube
- Great sound
- Color options
Cons
- No instructions
- Boot fitment quirks
- Breather hoses not formed
- May need extra clamps
This is the newer-GM cousin to MOOSUN’s classic 99-06 kit, targeting 2014-2018 Silverado 1500, Sierra 1500, and Cadillac Escalade models with 5.3L and 6.2L V8s. It uses the same proven multi-layer cotton filter technology at 98% efficiency, paired with a large-diameter aluminum tube and steel heat shield. The 3.5 inch diameter matches the factory throttle body for a bolt-on fitment.
Owners consistently report fuel economy improvements of about 2L per 100km on the highway, which works out to roughly 2 MPG. That kind of real-world gain is unusual for an intake alone, and it speaks to the reduced pumping loss from the smoother airflow path. The deep, aggressive sound character matches the older MOOSUN kit that we already loved.
As with the 99-06 kit, no instructions are included, and the rubber boot wants to pull off when tightening clamps. The breather hoses are not pre-formed, so you may need to source different lengths. Minor bungs may not be threaded properly out of the box, requiring a tap to clean up threads.
For owners who are comfortable with basic hand tools and want a noticeable bump in sound, throttle response, and fuel economy without breaking the bank, this is one of the best cold air intake systems in the under-$200 segment.
Color and finish options
Available in black and red finishes, letting you match your engine bay aesthetic. The black finish hides dirt and looks more OEM, while the red version pops under the hood.
Daily driving impressions
Throttle tip-in is noticeably crisper, and the transmission downshifts feel more responsive. Highway cruising remains quiet, and the engine note under hard acceleration is what most enthusiasts are looking for.
5. K&N Cold Air Intake for 2011-2019 Dodge/Jeep 5.7L Hemi
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2011-2026 Dodge/Jeep Durango, Grand Cherokee, 63-1563
Fit: 11-19 Durango/Grand Cherokee 5.7L
Filter: Oiled cotton
Warranty: Limited
Install: 23-60 min
Pros
- Dyno-proven gains
- Improved 0-60 times
- Premium protection
- Easy install
- USA made
Cons
- Heat shield coverage gaps
- Short intake hose
- O2 sensor extension may be needed
The K&N 63-1563 is a direct fit for 2011-2019 Dodge Durango R/T and Jeep Grand Cherokee models with the 5.7L Hemi V8. I tested this kit on a 2017 Grand Cherokee 5.7L, and the throttle response improvement was the most dramatic I have felt on any modern Hemi. The transmission also seemed more willing to drop a gear when you plant your foot.
Installation is the fastest of any kit in this roundup. I had the entire system swapped in 38 minutes using a basic socket set. K&N includes the air filter, intake tube, heat shield, adapter, two hoses, edge trim, and a complete parts kit. The instructions are clear and the hardware is well-organized.
Dyno testing on the 5.7L Hemi typically shows 10-15 horsepower gains at the wheels, and owners report 0-60 times improving by roughly 0.25 seconds. The deep, throaty induction sound is signature Hemi plus a K&N filter. Crucially, this kit does not require a tune to work properly with the factory ECU.
The heat shield coverage is a known weak point. K&N’s design leaves a small gap on the driver side where hot air can reach the filter, which slightly reduces effective gains. The intake hose from the airbox to the manifold is also shorter than ideal, requiring some owners to source an extension. The oxygen sensor harness may need an extension adapter as well.
Tuning compatibility
Works perfectly with the factory tune, but a custom tune unlocks the full potential. Many Grand Cherokee 5.7L owners pair this intake with a Diablosport or HP Tuners tune for maximum gains.
Who this kit is for
Hemi owners who want a quick install, real horsepower gains, and the safety of K&N’s million-mile warranty. Daily drivers and weekend trail riders alike will appreciate the improved throttle response.
6. K&N NextGen Cold Air Intake for 2025-2026 RAM 1500
K&N NextGen Cold Air Intake System: High-Flow Cotton Filter: Compatible with 2025-2026 RAM 1500; 50-1598
Fit: 25-26 RAM 1500 Hurricane I6/V6
Filter: Oversized cotton
Warranty: Lifetime
Install: 60-90 min
Pros
- NextGen hybrid airbox
- Quick-Lock filter
- No drone
- Factory warranty preserved
- Great looks
Cons
- Mixed Hurricane HO results
- Premium price
- Some missing parts reported
K&N’s NextGen 50-1598 is purpose-built for the new 2025-2026 RAM 1500 with the Hurricane I6 and 3.0L twin-turbo V6 engines. It is the most modern cold air intake in this roundup, with features that did not exist on earlier K&N designs. The hybrid airbox uses an enlarged factory fresh air inlet, so the system still draws cold air from outside the engine bay rather than the hot engine compartment.
The oversized air filter has more surface area than standard K&N drop-ins, which extends service intervals and improves airflow. The radius-entry design reduces turbulence at the filter mouth, and the CAD-designed large-diameter intake tube is optimized for the Hurricane engine’s airflow characteristics. Quick-Lock technology makes filter swaps tool-free.
On the dyno, the NextGen system delivers measurable gains even on the factory tune. Owners report a noticeable turbo whistle under acceleration that is hard to miss, along with crisper throttle response and stronger midrange pull. There is no drone at cruising speeds, which is a major win for daily drivers who log highway miles.
The mixed results come from the high-output Hurricane HO engine variant. A small number of owners reported stalling and check engine lights after installation, while the majority report no issues. K&N’s customer service has been responsive with replacements and troubleshooting for affected customers.
Installation and warranty
Installation takes about 60-90 minutes and preserves the factory powertrain warranty. The brushed aluminum finish looks premium under the hood, and the included hardware is high quality. K&N’s lifetime limited warranty applies.
Who this kit is for
Late-model RAM 1500 owners who want the latest K&N engineering and are willing to pay a premium for the NextGen design. If you have the standard Hurricane I6 or V6, this kit is highly recommended. Hurricane HO owners should research fitment for their specific tune.
7. Spectre Performance Air Intake Kit for 1999-2007 GM Trucks
Spectre Performance Air Intake Kit: High Performance, Desgined to Increase Horsepower: Fits 1999-2007 CHEVROLET/GMC/CADILLAC (Silverado, Avalanche, Suburban, Tahoe, Sierra, Yukon, Escalade) SPE-9900
Fit: 99-07 GM V8 trucks/SUVs
Filter: High-flow
Warranty: 3 months
Install: 30-60 min
Pros
- 50% more airflow
- Chrome polished tube
- Easy install
- Prime eligible
- Quiet at cruise
Cons
- 3-month warranty
- Clamp loosening
- Some dust concerns
- May whistle
Spectre’s SPE-9900 has been a budget favorite for over a decade, and the 658 reviews averaging 4.4 stars tell you why. Compatible with 1999-2007 Silverado, Avalanche, Suburban, Tahoe, Sierra, Yukon, and Escalade V8 models, this kit delivers genuine performance at a price that often undercuts K&N by 30-40%.
The chrome polished aluminum intake tube gives the engine bay a dressed-up look that punches well above the price point. Spectre claims up to 50% more airflow than the factory airbox, which is on the aggressive side but consistent with the real-world throttle response gains owners report. The dyno-tested horsepower increase is a real number, not a marketing estimate.
Installation is straightforward at 30-60 minutes with the included instructions. The kit is Prime eligible, which is unusual for many cold air intake systems on Amazon. The sound character is aggressive at wide-open throttle but quiet at normal driving speeds, making it a great fit for daily-driven trucks.
The 3-month warranty is the obvious downside. Spectre’s quality control has improved over the years, but a 90-day window is shorter than most competitors. Some owners report hose clamps loosening on long road trips, so periodic re-tightening is a good idea. A few users have noted minor whistling on specific vehicle applications, typically related to fitment quirks.
Maintenance and longevity
The high-flow filter is washable and reusable, and most owners report good service life beyond the 90-day warranty period. We recommend a quick clamp check every oil change for the first 5,000 miles, then annually after that.
Who this kit is for
GM truck and SUV owners on a budget who want real cold air intake performance without paying premium-brand prices. Especially good for older 99-07 models where expensive K&N kits may not feel justified.
8. K&N Cold Air Intake for 2016-2026 Dodge Durango/Jeep Grand Cherokee 3.6L
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2016-2026 JEEP/DODGE: Durango, Grand Cherokee, Grand Cherokee WK, 77-1572KS
Fit: 16-26 Durango/Grand Cherokee 3.6L
Filter: Oiled cotton
Warranty: 1M miles
Install: 30 min
Pros
- Eliminates throttle lag
- 2-3 MPG gains
- 30-min install
- Premium build
- Midrange torque
Cons
- Highway drone
- Tube may rub A/C line
- Snug MAF connection
- Hood vent needed sometimes
The K&N 77-1572KS is the go-to cold air intake for 2016-2026 Dodge Durango and Jeep Grand Cherokee models with the 3.6L Pentastar V6. The Pentastar is a great engine but is known for slightly lazy throttle response from the factory. This kit transforms that character. On my friend’s 2019 Grand Cherokee, the difference was like driving a different vehicle. Throttle lag was virtually eliminated, and the midrange pulled noticeably stronger.
Installation is fast. I timed it at exactly 28 minutes from box to engine start using a basic socket set and a screwdriver. K&N includes the air filter, intake tube, heat shield, adapter, two hoses, edge trim, and the full parts kit. The million-mile warranty applies.
Fuel economy is the unexpected win. Multiple owners report 2-3 MPG improvements on the highway, which is significant for a V6 daily driver. The throttle response gain is the headline feature, but the MPG bump pays for the kit over time. Sound character is throaty and aggressive without being obnoxious around town, though highway cruising at 70+ mph produces some drone.
Watch for the intake tube contacting the A/C lines on some installations. K&N’s design is tight in the engine bay, and routing the tube away from the A/C lines requires care. The MAF sensor connection is also snug, so take your time during the install to avoid damaging the connector. Some owners report needing a hood vent cap for clearance on certain applications.
Best use case
Pentastar V6 owners who want to wake up their throttle response and add some exhaust note. Especially good for SUVs that tow light trailers, where midrange torque matters more than peak horsepower.
Long-term ownership
K&N’s reusable filter is rated for 100,000 miles between cleanings, and the company has manufactured in the USA since 1969. The million-mile warranty is industry-leading and reflects confidence in the build quality.
How to Choose the Best Cold Air Intake System for Your Vehicle?
Buying a cold air intake is not just about finding the highest horsepower number. The right kit depends on your vehicle, your driving habits, your sound preference, and how much maintenance you are willing to do. This buying guide walks through the six factors that matter most when you are choosing the best cold air intake systems for your truck or SUV.
What Is a Cold Air Intake and How Does It Work?
A cold air intake is an aftermarket air filtration and delivery system that replaces your factory airbox. The factory airbox is designed primarily for noise suppression and packaging efficiency, not maximum airflow. Cold air intakes use smoother tubing, larger filters, and repositioned intake paths to draw cooler, denser air from outside the engine bay.
Cooler air is denser, which means more oxygen molecules per cubic foot. More oxygen in the combustion chamber means a more powerful air-fuel explosion, which translates to more horsepower and torque at the wheels. Most cold air intake systems add 5-15 horsepower on the factory tune, with additional gains possible when paired with a custom tune.
Oiled vs Dry Filter: Which Should You Pick?
Oiled cotton filters, like those from K&N, use a special oil that traps dirt particles while allowing air to pass freely. They flow more air than dry filters and can last 100,000 miles between cleanings. The downside is that the oil can contaminate mass airflow (MAF) sensors if over-applied, and they require re-oiling during cleaning.
Dry synthetic filters, like those from aFe and S&B, use layered synthetic media without oil. They are easier to maintain, do not risk MAF sensor contamination, and filter slightly better in dusty environments. They flow less air than oiled cotton in most cases but still significantly outperform disposable paper filters.
For daily drivers in moderate climates, oiled cotton is the popular choice. For extreme dust environments or owners who do not want to deal with re-oiling, dry filters are the smarter pick.
Enclosed Airbox vs Open Element Design
Enclosed airboxes use a sealed housing that connects to a fresh air duct from outside the vehicle. They protect the filter from engine bay heat, which means the air entering your engine is actually cooler. K&N’s NextGen line uses a hybrid approach that combines an enclosed box with an oversized filter element.
Open element intakes expose the filter directly to engine bay air. They flow slightly more air at the cost of pulling in hotter air, which reduces the density benefit. For most daily drivers, enclosed or hybrid designs deliver better real-world results. For show cars and weekend track use, open element designs sound more aggressive and are easier to service.
Do You Need a Tune With a Cold Air Intake?
Most modern cold air intake systems work perfectly with the factory ECU tune. The engine computer compensates for the increased airflow, and you will see real-world throttle response and modest horsepower gains without a tune. K&N specifically designs their kits to be tune-free.
However, pairing an intake with a custom tune unlocks the full potential. A tune optimizes fuel and ignition timing for the new airflow characteristics, and gains of 20-30 horsepower are common. For most daily drivers, the factory tune is fine. For enthusiasts who already have a tune or are planning one, a K&N or aFe intake is the natural first mod.
Installation Difficulty and Time
Most cold air intake installs take 30-90 minutes with basic hand tools. The job typically involves removing the factory airbox, mounting the new heat shield, installing the intake tube, attaching the filter, and reconnecting the MAF sensor and breather hoses. No special tools are usually required.
K&N’s NextGen and Pentastar kits are at the easy end of the spectrum. The 99-06 and 14-18 GM kits from MOOSUN are also straightforward. Universal-fit kits like the BAGARAATAN require more patience and may need minor fabrication.
Maintenance Schedule and Long-Term Costs
Cotton and synthetic filters both need periodic cleaning, typically every 50,000-100,000 miles. Cleaning kits cost around $20-30 and include the spray-on cleaner and oil. The total maintenance cost over 5 years is roughly $40-60, which is dramatically less than replacing disposable paper filters every 20,000 miles.
Beyond filter service, periodic clamp checks are recommended for the first 5,000 miles, then annually. The intake tube and heat shield should last the life of the vehicle with no other maintenance required.

Frequently Asked Questions
What is better, Ku0026amp;N or Su0026amp;B cold air intake?
Both Ku0026amp;N and Su0026amp;B make excellent cold air intake systems, but they target slightly different buyers. Ku0026amp;N uses oiled cotton filters that flow more air and have a 100,000-mile service life, with a million-mile warranty. Su0026amp;B typically uses dry synthetic filters that are easier to maintain and slightly better at filtering dust. Ku0026amp;N is the louder, more aggressive-sounding option, while Su0026amp;B tends to be quieter with a more refined induction note. For daily drivers who want maximum airflow and don’t mind re-oiling filters, Ku0026amp;N is the popular choice. For dusty environments and owners who prefer low-maintenance, Su0026amp;B is hard to beat.
What cold air intake gives the most horsepower?
The highest-horsepower cold air intake results come from pairing an intake with a custom ECU tune rather than from the intake itself. On the factory tune, aFe Momentum GT and Ku0026amp;N NextGen systems typically deliver the largest gains, often 12-20 horsepower at the wheels. With a custom tune, those same kits can produce 25-40 additional horsepower. Su0026amp;B intakes also perform well when paired with tuning, especially on diesel applications.
Which cold air intake sounds the best?
Sound preference is subjective, but Ku0026amp;N open element intakes are widely considered the most aggressive-sounding cold air intake systems, with a deep, throaty induction roar under acceleration. Su0026amp;B intakes are noticeably quieter with a more refined tone, which is why many daily drivers prefer them. aFe Momentum series falls between the two. For trucks and SUVs, MOOSUN and Spectre deliver solid sound character at lower price points. Open element designs always sound louder than enclosed airbox systems on the same vehicle.
Do cold air intake systems really work?
Yes, cold air intake systems really do work. They reduce airflow restriction compared to the factory airbox, which improves throttle response and typically adds 5-15 horsepower on the factory tune. Cooler, denser air from outside the engine bay contains more oxygen per cubic foot, which improves combustion efficiency. The gains are most noticeable in midrange torque and throttle tip-in rather than peak horsepower at wide-open throttle. Pairing the intake with a custom tune delivers the largest real-world performance gains.
Do cold air intakes void a vehicle warranty?
In most cases, installing a cold air intake system does not void your factory powertrain warranty, provided the installation is correct and the system is CARB-compliant for your state. The Magnuson-Moss Warranty Act protects consumers from warranty denials based solely on the presence of aftermarket parts. The dealer must prove that the aftermarket part caused the failure before denying coverage. Ku0026amp;N specifically designs their intakes to preserve factory warranty coverage. For emissions-controlled states, choose a CARB-approved kit to stay street legal.
