The Bully Dog Rapid Flow Induction system is a fully enclosed air intake system. This design is very effective at  keeping hot air out of the engine. The RFI cold air intake draws cold air in from sources around the engine bay resulting in an improvement in performance and efficiency. With extensive testing, Bully Dog designed an enclosed air intake system along with a high flow cotton gauze filter that yields better air flow and colder intake temperatures than a stock system and other aftermarket open intake designs.  Remarkably, the intake temperatures match ambient air temperatures at cruising speeds.

Available Vehicle Applications:

  • 2003-2007 Ford 6.0L Power Stroke**
  • 1994-1997 Ford 7.3L Power Stroke
  • 1999-2003 Ford 7.3L Power Stroke
**Ford used two different style intake sensors for the 6.0L Power Stroke.  They require different Bully Dog RFI Intakes to mount the sensors.  The most common design uses a square MAF (Mass Air Flow) sensor mounted with two screws.  The other type used by Ford was only used during part of the 2005 model year production and it consists of a round temperature sensor mounted to the intake tube using a rubber grommet.  Be sure to check which type of intake you have before ordering.  We are not responsible if you order the wrong intake.  The drop down menu next to the add to cart button will let you specify which intake you have based on the sensor design of your truck.

Results vs. stock air intake system.

  • Maximize Air Filter Cleaning Area
    • By using a conical air filter you can maximize the air filter cleaning area and allow the engine to breath easier giving you more horsepower.
  • Lifetime Reusable Gauze Filter
    • All RFI Induction systems use a lifetime reusable four layer cotton gauze filter that features an inverted cone design on the end of the filter. This unique design creates a greater surface area of filter media that enables it to trap dust particles as small as 0.50 micron.
    • Reusable - It is no longer necessary to spend hard earned money on OEM paper filters
  • Ideal for Performance Use
    • A greater surface area of filter media, combined with the RFI's deep pleat design, makes this filter ideal for high performance use.
  • Easy Installation
    • The installation of these systems is extremely easy and requires only basic hand tools.
  • Compatible
    • The Rapid Flow Induction works exceptionally well in conjunction with performance modules. The modules increase the amount of fuel going into the motor and create a need for increased air flow to lower exhaust temperatures. The end result is improved driveability, fuel mileage (improvement will vary), and acceleration.
  • Featured Design
    • The design of the air box draws cold air in, resulting in better performance.
