The AEM 21-852C Performance Cold Air Intake System for your 2016-2018 Ford RS (2.3L) 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 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 Intake Air Temperature (IAT) sensor mounts directly on the intake tube. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
