The AEM 21-8128DC cold air intake replaces the restrictive factory air filter and intake housing on specific Ford F-150 EcoBoost models with a system engineered, tuned, and dyno-tested for horsepower and torque gains. Air enters through an oversized dual AEM Dryflow synthetic washable filter mounted in the stock air box location and shielded from underhood heat, while mandrel-bent aluminum tubes finished in gunmetal gray powder coat route air to the throttle body. The system retains the factory intake air temperature sensor for an easy installation with common hand tools.
