Best Cold Air Intakes for 2021-2024 F-150 EcoBoost

A cold air intake is one of the first bolt-on upgrades most 2021-2024 Ford F-150 EcoBoost owners install, and for good reason. The factory airbox feeds a twin-turbocharged 3.5L V6 rated at 400 horsepower and 510 lb-ft of torque — 450 horsepower in the Raptor's High-Output tune — an engine that responds directly to cooler, higher-volume airflow. Because the EcoBoost is force-fed, it rewards a free-flowing cold air intake more than a naturally aspirated engine would: less restriction ahead of the turbos means quicker spool, sharper throttle response, and a deeper induction note under boost. In this buyer's guide we compare the best cold air intakes for the 2021-2024 F-150 3.5L EcoBoost that we stock and ship from our shop in Tampa, FL, with real dyno figures, filter and tube materials, fitment, and pricing so you can pick the right one the first time.

Do Cold Air Intakes Add Horsepower on the F-150 EcoBoost?

Yes. On a twin-turbocharged 3.5L EcoBoost F-150, a quality cold air intake can add roughly 15 to 27 horsepower and up to 40 lb-ft of torque at the crank, because the turbos amplify any reduction in intake restriction. K&N's dyno testing of its NextGen system for the 2021-2024 F-150 shows a measured airflow increase of 24.6% on the driver side and 33.25% on the passenger side over the restrictive factory airbox, which translates to +27.20 horsepower and +40.29 lb-ft of torque with no tune required.

The reason the gains are bigger on a turbo engine than on a naturally aspirated one comes down to how the EcoBoost makes power. The turbos have to draw every cubic foot of air through the factory filter and airbox before compressing it; a larger conical filter and a smooth, mandrel-bent or molded intake tube lower that pre-turbo restriction, so the turbos reach target boost sooner and work less hard to hold it. A well-designed intake also pulls cooler air and shields the filter from under-hood heat, dropping intake air temperatures (IATs) — and cooler, denser air is exactly what a forced-induction engine wants, especially in Florida heat. You will feel it most as crisper part-throttle response and a stronger mid-range pull under boost.

The Best Cold Air Intakes for the 2021-2024 F-150 3.5L EcoBoost

We ranked these four intakes on measured airflow, build quality, ease of installation, warranty, and value. All four are direct-fit, bolt-on systems that reuse the factory mass-air-flow (MAF) sensor calibration, so the three EcoBoost options below run correctly with no tune. Prices reflect current NLP Performance pricing at the time of writing.

1. K&N 21-24 F-150 3.5L V6 NextGen Cold Air Intake – Best Overall

The K&N NextGen (part 50-2617) is the intake we recommend to most 2021-2024 F-150 EcoBoost owners. It fits both the 2.7L and 3.5L EcoBoost V6, including the Raptor, and uses a high-density polyethylene (HDPE) rotationally molded intake tube that resists heat soak better than a bare aluminum tube. K&N pairs it with an oversized, washable High-Flow cotton-gauze filter rated to go up to 100,000 miles between cleanings, and the whole system installs in about 30 minutes with hand tools. The headline number is the dyno-verified +27.20 horsepower with no tune — the largest verified, no-tune gain in this guide.

2. Injen Power-Flow Air Intake (Midnight Black) – Best for 2.7L & 3.5L EcoBoost

Injen's Power-Flow (part PF9032RB) is the widest-fitting intake in this guide, covering 2015-2025 F-150 and 2018-2024 Expedition models with the 2.7L or 3.5L EcoBoost. Injen positions the filter in the coolest part of the engine bay and seals it behind a heat shield to keep hot under-hood air out, which drops intake air temperatures and feeds denser air to the turbos. The kit is a complete, direct-fit install with everything needed in the box, and like the K&N it retains the factory MAF calibration so no tune is required. It is backed by Injen's Limited Lifetime Warranty — the strongest coverage here — and the Midnight Black powder-coated finish looks clean under the hood. It carries a premium price, and it is a special-order item, so plan for lead time.

3. aFe Track Series Carbon Fiber Intake – Best for the Raptor (3.5L HO)

If you own a Raptor with the 450-horsepower 3.5L High-Output EcoBoost, the aFe Track Series (part 57-10031K) is the premium pick. It is built around a CAD-designed, dyno-refined carbon fiber intake tube inside a one-piece sealed housing that shields the filter from engine heat while looking like a factory-optional upgrade. A large 9-inch, 360-degree radial-flow filter with a 5.5-inch flange and a pre-oiled Pro 5R media maximizes surface area and airflow, and it produces the most aggressive induction sound in this comparison. At $820.00 it is the most expensive intake here, and it is Raptor-specific, but nothing else in this guide matches its airflow ceiling or its carbon-fiber presentation.

4. K&N 18-24 F-150 3.3L V6 Intake – Best for the Non-EcoBoost V6

Not every 2021-2024 F-150 runs the EcoBoost. If your truck has the base 3.3L Duratec V6, the K&N 77-2619KC is the intake to buy. This naturally aspirated engine will not see EcoBoost-sized gains — there are no turbos to amplify the airflow — but K&N still guarantees an increase in horsepower and torque, and the mandrel-bent aluminum tube plus a washable red High-Flow filter sharpen throttle response and add induction sound for $381.21. It is a straightforward, no-tune upgrade for the non-EcoBoost V6 owner who wants the K&N filter-for-life ownership experience.

Here is how the four intakes stack up on the specs that matter most when choosing. The K&N NextGen wins on value and no-tune power; the aFe Track Series wins on airflow and looks for Raptor owners.

Oiled vs Dry Filter, and Do You Need a Tune?

The three EcoBoost intakes in this guide do not require a tune. Each one reuses the factory MAF sensor and housing geometry that the truck's PCM is already calibrated for, so the engine reads airflow correctly out of the box and there is no check-engine light. A tune is optional: adding an ECU calibration on top of the intake can unlock larger, boost-and-timing-based gains, but it is not needed for the intake to run safely.

On filter media, the K&N and aFe systems here use oiled cotton-gauze filters, which capture fine dust well and are washable and reusable for the life of the truck — you clean and re-oil them roughly every 100,000 miles under normal driving. Dry synthetic filters (aFe also offers a Pro DRY S version of the Track Series) skip the oiling step and are the easy choice if you want zero-maintenance cleaning or worry about over-oiling near the MAF sensor. Both flow well; the choice is about maintenance preference, not power. One important note for California buyers: these performance intakes are not CARB-exempt, so we cannot ship them to California addresses.

How to Install a Cold Air Intake on Your F-150 EcoBoost

Installing a cold air intake on a 2021-2024 F-150 EcoBoost is a 30-to-45-minute driveway job that needs only basic hand tools: an 8mm and 10mm socket, a flat-blade screwdriver or pick for the spring clamps, and a Torx driver for a couple of shield bolts. Start with the engine cold. Disconnect the MAF sensor connector and loosen the clamp at the throttle-body or turbo inlet, then lift the factory airbox and intake tube out as an assembly. Transfer the MAF sensor into the new intake tube using the supplied hardware, seat the new filter and heat shield, and reconnect the MAF connector. Snug all clamps, double-check that nothing contacts a moving or hot component, and reconnect the battery if you disconnected it.

Handle the MAF sensor carefully — it is the one part the engine relies on to meter airflow, and a dirty or damaged sensor is the most common cause of rough running after any intake install. No tune, relearn, or reset is required; start the truck, let it idle for a minute, and take it for a short drive.
