AEM 21-714C Cold Air Intake System

Boost your 2012–2014 Honda Civic 1.8L's performance with the AEM 21-714C Cold Air Intake System, designed to increase horsepower, torque, and throttle response by replacing the factory air intake assembly. Engineered, tuned, and dyno-tested for this specific Civic application, the system features a free-flowing mandrel-bent aluminum intake tube finished in a sleek and durable gunmetal gray powder coat. Air is drawn through an oversized AEM Dryflow synthetic air filter, which is oil-free, washable, and reusable—providing excellent filtration and airflow. The filter is strategically placed outside the engine bay to draw in cooler air, reducing intake temperatures and improving combustion efficiency. With a simple bolt-on design, this intake system installs easily using standard tools and integrates with the Civic’s factory emissions components for seamless fit and function. It’s a proven performance upgrade backed by AEM’s Lifetime Limited Warranty.
