The Bully Dog Rapid Flow Induction (RFI) is an advanced airflow induction intake system built to increase the engine’s ability to breath. By replacing the restrictive stock intake 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 Rapid Flow Inductions inductions use a lifetime reusable 4” layer cotton gauze filter. This design, combined with deep pleats, make these filters ideal for high performance use. The Bully Dog RFI induction also works very well in conjunction with performance computer modules, programmers, or chips. The perfromance modules will increase the amount of fuel going into the motor and will therefore increase the need for more air. The installation of the RFI system is very easy and requires only very basic hand tools. Installation can generally be done in 20 minutes or less.
  • Increased Flow:  The Rapid Flow Induction Intake System allows your engine to breath.  The Bully Dog RFI intake was developed to allow your engine to breath larger amounts of colder air giving your vehicle a boost in both power and fuel economy.
  • Conical Filter:  The RFI intake uses a conical airfilter that maximized the air filter cleaning area, allowing the engine to breathe easier.
  • Enclosed Design:  The Rapid Flow Induction Intake features an enclosed design that creates a barrier between the engine compartment and the air filter.  This keeps engine heat out and allows only cold air to be pulled into the engine.
  • Lifetime Filter:  The air filter used on the RFI isa  lifetime reusable 4" layer cotton guaze filter.  The filter is cleanable and features deep pleats making it ideal for high performance use.
  • Performance Intake:  The Rapid Flow Induction Intake was designed by Bully Dog to go hand in hand with other performance modifications.  The RFI is ideal for vehicles with performance chips, exhausts, injectors, turbos, and other performance enhancements that require greater airflow to maximize their output.
  • Easy Installation:  The RFI offers very easy installation and requires only simple hand tools.  Generally, installation should take 20 minutes or less.
