AEM Dryflow Cold Air Intake - Lexus IS300 2.0T (2018-2025)
21-791C - AEM Dryflow Cold Air Intake - Lexus IS300 2.0T (2018-2025)
The AEM 21-791C Performance Cold Air Intake System replaces the restrictive factory air filter and intake housing to improve airflow, horsepower, torque, and throttle response. It is specifically designed, tuned, and dyno-tested for compatible Lexus IS200t 2.0L turbocharged models.
Air enters through an oversized AEM Dryflow synthetic washable air filter designed for excellent airflow, filtration, and performance. The filter mounts in the factory air-box location and is protected by a heat shield intended to reduce intake-air temperatures.
The mandrel-bent aluminum intake tube features a durable gunmetal-gray powder-coated finish. The system accommodates the vehicle's factory emissions-control equipment, including the valve-cover breather hose, and installs using commonly available tools.
