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.
Innovation has always been AEM's core competency. As J.C. would say "if you can't make something better, why make it all?" This "make it better" drive combined with our commitment to the sport compact market continues to distinguish AEM from the many company's offering "Me Too" copycat products. Our innovations are inspired by a passion for engineering excellence, being there and getting our hands dirty, the only way to really understand technology enough to make it better. The company continues to lead the way with innovative products that push the envelope of what is possible.
