Product Description

The AEM 21-797C Cold Air Intake System is a performance intake upgrade engineered specifically for **2016-2018 Volkswagen Jetta models** equipped with the 1.4 L turbocharged inline-four engine. This system replaces the restrictive factory air filter and housing with a tuned mandrel-bent aluminum intake tube and oversized Dryflow synthetic washable air filter, improving airflow and throttle response while helping boost engine power. The heat shield helps reduce intake air temperatures by shielding the filter from hot engine bay air.

AEM's Dryflow media is washable and reusable, eliminating the need for filter oil and simplifying maintenance. Designed to integrate with factory emissions and breather components, installation requires only common hand tools. The system delivers performance benefits, including estimated gains of up to ~11 HP and ~14 lb-ft of torque under ideal conditions, and is backed by a limited lifetime warranty. Note that the intake is **not legal for sale or use in California** or other states adopting California emission standards unless otherwise specified by local regulators.
