AEM 21-8128DC Cold Air Intake System

✔ Vehicle Fitment — What the AEM 21-8128DC Fits

According to the manufacturer and fitment listings, this intake system applies to:

• 2015–2021 Ford F-150 trucks with the EcoBoost engine (specifically the 2.7 L and 3.5 L V6 turbo versions).

• Compatible trims include XL, XLT, Lariat, King Ranch, Limited, etc, as long as the engine type matches.

Be sure to verify your engine displacement and turbo version before purchasing.

The AEM 21-8128DC Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Ford F150 EcoBoost models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance.

Why Upgrade Your F-150 EcoBoost with the AEM 21-8128DC?

Because your turbo V6 deserves better than a limp stock intake.

With the 21-8128DC you’ll get:

• Improved airflow compared to the factory intake path — the intake replaces restrictive ducts and taps into cooler air.

• Sharper throttle response — quicker spool, cleaner airflow, more direct engine feel.

• Deeper induction/engine sound — you’ll actually hear the turbos and airflow rather than the muffled stock intake.

• High-quality build: mandrel-bent aluminum tubing finished in gunmetal grey, oversized AEM Dryflow washable filter, and heat shield to reduce intake air temperature.

• Dyno-proven gains: AEM lists estimated gains of +17 HP at ~5200 RPM for this kit

If you’re upgrading your F-150 for performance (or just want it to feel like more than a commuter truck), this intake is a solid step.

The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The air intake tubes are constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the intake air temperature sensor.

Key Features of the AEM 21-8128DC Cold Air Intake

• Mandrel-bent aluminum intake tubes, powder-coated gunmetal for durability and heat resistance.

• Oversized AEM Dryflow synthetic filter: oil-free, washable, reusable, rated for up to 100,000 miles before cleaning (depending on driving conditions).

• Heat shield and optimized filter placement in the original airbox space to reduce intake air temps and avoid heat-soak.

• Direct design to accommodate factory sensors (MAF, IAT) and emissions hardware—designed as a bolt-on replacement.

• Backed by AEM’s limited lifetime warranty.

The dual intake AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions).

Performance Expectations for the EcoBoost F-150

Upon installing this intake on the EcoBoost platform you can expect:

• Faster throttle tip-in and more responsive driving feel.

• More sustained airflow under boost, which can enhance spool behaviour and boost ramp especially if paired with other mods.

• A more aggressive induction sound (turbo whine, intake inhale) without going overboard.

• Slight horsepower/torque gains out of the box; bigger gains if you follow up with tuning, exhaust, or intercooler upgrades.

• Cooler intake air temperatures under load thanks to improved location and heat-shielding design.

While it won’t turn your F-150 into a supercar, it will make the EcoBoost feel significantly more alive.

The air intake system is easy to install with commonly available tools and it is backed by AEM’s Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
