"The AEM short ram intake works as advertised and increased the horsepower and fuel mileage of my Focus. The product is made of quality material and installed with no problems. The instructions were simple to follow and were correct for my car. I have had the intake installed for about 3 weeks and have documented an increase in fuel milage of 3 miles to the gallon more than before installing the intake. I am well pleased." —Rodney H from Buffalo Junction, VA bought an AEM Short Ram Intake System for a 2001 Ford Focus.
