Product Description

The AEM 21-883DS Cold Air Intake System is a precision-designed performance upgrade for the 2021-2025 Hyundai Elantra with the 2.0L inline-4 engine. It replaces the factory intake path with a high-flow setup that draws in cooler air, helping to improve combustion efficiency, throttle response, and overall engine performance.

Featuring a washable DryFlow® synthetic filter that doesn't require oil, the system offers up to ~100,000 miles of use before cleaning - reducing maintenance. The intake setup also includes a custom hump hose and a heat shield with a lid to reduce the impact of engine heat and keep intake air cooler.

Dyno testing shows an estimated gain of around 9.12 HP. The system installs with basic hand tools in about 60-90 minutes, and comes backed by AEM's Lifetime Limited Warranty.
