Cold Air Intake for 2024-2026 Toyota Tacoma: K&N vs aFe

A cold air intake is the first bolt-on most 2024-2026 Toyota Tacoma owners reach for, and for good reason: the new truck finally runs a turbocharged 2.4L i-FORCE engine that breathes far better than the old 3.5L V6 ever did. Swap the restrictive factory airbox for a high-flow system and you free up intake airflow, sharpen throttle response, and get the audible turbo whoosh and blow-off chatter the stock box muffles. The three systems that dominate the fourth-generation Tacoma market right now are the K&N NextGen Aluminum intake, the aFe Momentum GT, and the COBB SF — and they take three genuinely different approaches to the same goal.

Why the 2024-2026 Tacoma 2.4L Turbo Responds to a Cold Air Intake

The fourth-generation Tacoma dropped the naturally aspirated 3.5L V6 for a turbocharged 2.4L inline-four (the i-FORCE), and a turbo motor is far more sensitive to intake restriction than the old V6. Depending on trim and transmission, the gas 2.4L turbo makes 228 horsepower and 243 lb-ft in the base SR, up to 278 horsepower and 317 lb-ft in SR5, TRD Sport, TRD Off-Road, Limited, and TRD Pro grades with the 8-speed automatic, and 270 horsepower with the 6-speed manual. The i-FORCE MAX hybrid adds an electric motor for 326 horsepower and 465 lb-ft.

A turbo pulls a large, continuous volume of air, so the factory paper filter and narrow airbox snorkel become a measurable bottleneck once the compressor spools. An aftermarket cold air intake widens the tube, swaps in a high-flow filter with several times the surface area, and — on the sealed designs — isolates that filter from under-hood heat. The result on these 2.4L turbo trucks is quicker spool, crisper throttle tip-in, and a louder induction note, with modest peak gains that the manufacturers put in the low-double-digit horsepower range. At our Tampa shop, the change owners notice first is throttle response in the 2,000-3,500 rpm range where the turbo lives day to day.

K&N vs aFe vs COBB: 2024-2026 Tacoma Intakes at a Glance

All three systems bolt to the same 2.4L turbo and all three use a washable, reusable filter, so you never buy a replacement element. The real decisions are filter media (oiled cotton vs dry synthetic), whether the airbox is fully sealed, warranty, and price. Here is how the three stack up for the fourth-generation Tacoma.

K&N NextGen Aluminum Cold Air Intake (Our Top Pick)

The K&N NextGen Aluminum intake (part number 70-9043) is the safest all-around choice for the 2024-2026 Tacoma 2.4L turbo. It fits every 2.4L turbo trim in the lineup, pairs a mandrel-bent polished aluminum charge tube with K&N's washable High-Flow cotton-gauze filter, and carries the industry's most generous coverage: K&N's 10-year/million-mile limited warranty. The reusable filter is cleaned and re-oiled roughly every 100,000 miles, so you never buy another element for the life of the truck.

aFe Momentum GT: Best Value and Most Airflow

If you want the most sealed, highest-airflow system for the money, the aFe Momentum GT is the one. It is built around a fully enclosed roto-molded housing and an 8-inch-tall, 360-degree radial-flow Pro 5R filter with a 4-inch flange and five progressively finer layers of oiled cotton gauze. aFe rates the Momentum GT at up to 15 more horsepower and 17 lb-ft of torque, with 20-27% more airflow than the restrictive factory intake — manufacturer figures, but in line with what a sealed box plus a filter this large should deliver. At the mid-$400s list (and currently discounted below that), it undercuts the K&N by roughly $100 while adding a true sealed airbox, which is why it is our value pick.

COBB SF Intake: Best for Tuned Trucks

The COBB SF Intake System is the choice if you are building a tuned Tacoma. It uses a dry synthetic filter in a sealed airbox, so there is no filter oil to maintain and no risk of over-oiling a mass-airflow sensor. COBB designs its intakes to work within its wider tuning ecosystem, making it the natural match for owners planning an Accessport or staged power package down the road. It fits the 2024-and-up Tacoma and the 2025-and-up 4Runner with the 2.4L turbo, and lands in the mid-$400s — between the aFe and the K&N on price.

Oiled vs Dry Filter: Which Should You Run?

Oiled cotton-gauze filters (the K&N and the aFe Pro 5R) generally flow a touch more air and trap fine dust well, but they must be re-oiled after cleaning, and over-oiling can leave residue on a mass-airflow sensor. Dry synthetic filters (the COBB SF) skip the oil entirely: you wash them with water, let them dry, and reinstall, with zero risk of MAF contamination. For a daily-driven Tacoma that mostly sees pavement, either is fine. For a heavily tuned truck where a clean MAF signal matters, or if you simply never want to think about filter oil again, the dry COBB has the edge. aFe also offers the same Momentum GT with its Pro DRY S synthetic media if you prefer the sealed aFe box with a dry filter.

Is a Tacoma Cold Air Intake CARB Legal?

None of these three intakes is currently CARB-approved for the 2024-2026 Tacoma 2.4L turbo, which means they are sold for off-road and competition use only and are not legal for sale or use on pollution-controlled vehicles in California or states that follow CARB emissions rules. We cannot ship them to California addresses. If you live in a CARB state and drive on public roads, confirm the law before buying; outside those states, all three install and run with no issue. This is purely an emissions-certification matter — it has nothing to do with the quality or performance of the parts.

Installation: What to Expect

All three systems are a straightforward driveway install that takes most owners 30 to 60 minutes with basic hand tools — a socket set, screwdrivers, and a trim tool. You remove the factory airbox and intake tube, transfer or reroute any sensors and the breather connection, and bolt the new housing and tube in place. No cutting is required. The K&N and aFe need no tune and will not throw a check-engine light on the stock calibration. The COBB SF is tune-ready and delivers its full benefit when paired with a COBB Accessport calibration, though it bolts on and runs without one. Remember that oiled filters (K&N, aFe Pro 5R) need a light re-oil after each cleaning; the COBB dry filter does not.
