Description

AEM cold air intake systems are designed to increase horsepower and torque. The system includes an oversized AEM DRYFLOW synthetic washable air filter, engineered to provide outstanding airflow, filtration, and performance, and also features a mandrel-bent aluminum intake tube and high quality hardware. The oversized, conical filter design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the factory fresh air duct attaches to the heat shield. The entire system can typically be installed in less than 90 minutes.
