Product Description

The AEM 21-858C Cold Air Intake System is a performance-tuned induction upgrade designed for **2019-2024 Kia Forte** and **2020 Hyundai Elantra** models equipped with the 2.0 L gasoline engine. By replacing the restrictive factory intake path with a high-flow mandrel-bent aluminum tube and oversized Dryflow synthetic washable air filter, this system increases airflow and reduces intake air restriction to help improve horsepower, torque, and throttle response over stock. The inclusion of a custom shaped heat shield with edge trim lining helps to reduce heat soak from the engine bay, delivering denser air charge for more efficient combustion.

Featuring an oil-free Dryflow filter media that can provide up to approximately 100,000 miles of reliable service between maintenance intervals, the 21-858C is backed by AEM's limited lifetime warranty for long-term performance support. Installation is straightforward as a bolt-on upgrade with the included hardware and clamps, using only common hand tools. Enthusiasts will enjoy enhanced engine sound and a modest performance boost, with an estimated gain of about **6.7 HP and 4.9 lb-ft of torque** under ideal conditions. Before purchasing, verify local emissions compliance, as this intake is **not legal for sale or use in California** and other CARB states on pollution-controlled motor vehicles.
