The AEM 21-811C Performance Cold Air Intake System produces horsepower and torque gains by improving air flow and drawing in cooler, denser air. It all begins with a cone shaped AEM Dryflow filter which uses a synthetic filter media for outstanding air flow, filtration and performance. By relocating the air filter lower and to the front of the car, cooler and denser air can be accessed. Oiling the filter is not necessary and it can be used up to 100,000 miles before cleaning is needed (depending on driving conditions). Running up to the throttle body is the intake tube which is mandrel-bent to reduce airflow restriction at the bends. It is made of aluminum and is powder coated gray for lasting performance. The restrictive factory air pipe and air box are replaced with this free-flowing air intake system. The factory PCV valve and recirculation hose mount directly on the intake tube.
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.
