Bully Dog Rapid Flow Induction Kit 221103 99-03 Ford 7.3l PowerStroke Diesel

The RFI™ is an advanced airflow induction built to increase the engines ability to breath. By replacing the restrictive stock induction, RFI™ increases horsepower, torque, fuel efficiency, and decreases exhaust gas temperatures. By removing the stock air box, replacing it with a metal heat shield, and using a conical air filter you can maximize the air filter cleaning area and allow the engine to breathe easier and produce more horsepower. All RFI™ inductions use a lifetime reusable 4” layer cotton gauze filter. This design, combined with deep pleats, make these filters ideal for high performance use. This induction also works very well in conjunction with performance computer modules. The modules will increase the amount of fuel going into the motor and will therefore increase the need for more air. The installation of this system is very easy and requires only very basic hand tools. Installation can generally be done in 20 minutes or less.
