Ford 6.4L Power Stroke '08-'09
Rapid Flow Induction, enclosed, Polyethylene Stage 1
Part # 51103
The RFI™ is an advanced airflow induction system built to increase the engine’s ability to breathe; thus increasing horsepower, torque and fuel efficiency, while decreasing exhaust gas temperatures.
Most of our RFI™ systems are designed as an enclosed system. Our enclosed systems are designed with a few simple goals in mind: keep hot air out of the air intake stream, make sure systems seal tightly up to cold air sources from within the engine bay, accommodate a high flow cotton gauze air filter, and improve the look of the engine bay with a great looking intake. By following these simple goals we are able to provide colder air and more air to the engine. Thus providing better performance than a stock intake; the resulting benefits are improved fuel economy, more horsepower and torque, lower cost of ownership than some stock air intakes, and an upgraded look to engine bay.
