The AEM 21-784C cold air intake system adds horsepower and torque by replacing the restrictive factory air filter and intake housing on applicable Acura ILX models. Air enters through an oversized AEM Dryflow synthetic washable filter located in the original air box position and protected by a heat shield to reduce intake air temperature. The mandrel-bent aluminum tube has a durable gunmetal gray powder-coated finish and is designed to retain factory emissions devices, including the mass air flow sensor and PCV hose.
