Product details
Elevate your engine’s performance with the AEM 21-858C Cold Air Intake System, engineered to fit select 2020 Hyundai Elantra and 2019–2022 Kia Forte models. This high-performance intake system replaces your vehicle’s restrictive factory air intake components with a precision-tuned, dyno-tested design that delivers increased horsepower, torque, and throttle response. Constructed from mandrel-bent aluminum and finished in a durable charcoal gray powder coat, the intake tube not only performs but adds a sleek look under the hood. The oversized AEM Dryflow synthetic air filter is oil-free, washable, and reusable, providing excellent filtration and airflow. By relocating the filter to a cooler area of the engine bay, this system draws in colder, denser air for more efficient combustion. Easy to install and built to last, the AEM 21-858C is the perfect upgrade for drivers who want noticeable gains in power, sound, and reliability.
